Early history[edit]

Archaeological research, pioneered by Thurstan Shaw and Steve Daniels,[1] has shown that people were already living in south-western Nigeria (specifically Iwo-Eleru) as early as 11,000 BC[2]and perhaps earlier at Ugwuelle-Uturu (Okigwe) in south-eastern Nigeria, where microliths were used.[3] Smelting furnaces at Taruga dating from the 4th century BC provide the oldest evidence of metalworking in archaeology. The earliest known example of a fossil human skeleton found anywhere in West Africa, which is 13,000 years old, was found at Iwo-Eleru in western Nigeria and attests to the antiquity of habitation in the region.[4]
Microlithic and ceramic industries were also developed by savanna pastoralists from at least the 4th millennium BC and were continued by subsequent agricultural communities. In the south, hunting and gathering gave way to subsistence farming around the same time, relying more on the indigenous yam and oil palm than on the cereals important in the North. The stone axe heads, imported in great quantities from the north and used in opening the forest for agricultural development, were venerated by the Yoruba descendants of neolithic pioneers as "thunderbolts" hurled to earth by the gods.[4]
Kainji Dam excavations revealed iron-working by the 2nd century BC. The transition from Neolithic times to the Iron Age apparently was achieved without intermediate bronze production. Others suggest the technology moved west from the Nile Valley, although the Iron Age in the Niger River valley and the forest region appears to predate the introduction of metallurgy in the upper savanna by more than 800 years. The earliest identified iron-using Nigerian culture is that of the Nok culture that thrived between approximately 900 BC and 200 AD on the Jos Plateau in north-eastern Nigeria. Information is lacking from the first millennium AD following the Nok ascendancy, but by the 2nd millennium AD there was active trade from North Africa through the Sahara to the forest, with the people of the savanna acting as intermediaries in exchanges of various goods. Yoruba[edit]



Ife bronze casting of Oduduwa, dated around 12th century, in the British Museum. Historically the Yoruba people have been the dominant group on the west bank of the Niger. Their nearest linguistic relatives are the Igala who live on the opposite side of the Niger's divergence from the Benue, and from whom they are believed to have split about 2,000 years ago. The Yoruba were organized in mostly patrilineal groups that occupied village communities and subsisted on agriculture. From approximately the 8th century A.D., adjacent village compounds called ile coalesced into numerous territorial city-states in which clan loyalties became subordinate to dynastic chieftains. Urbanization was accompanied by high levels of artistic achievement, particularly in terracotta and ivory sculpture and in the sophisticated metal casting produced at Ife. The Yoruba paid tribute to a pantheon composed of an impersonal Supreme Deity, Olorun, and 400 lesser deities who perform various tasks. Oduduwa is regarded as both the creator of the earth and the ancestor of the Yoruba kings. According to one of the various myths about him, he founded Ife and dispatched his sons and daughters to establish similar kingdoms in other parts of what is today known as Yorubaland. Igbo states[edit]

Nri Kingdom[edit]

The city of Nri is considered to be the foundation of Igbo culture.[5] Nri and Aguleri, where the Igbo creation myth originates, are in the territory of the Umueri clan, who trace their lineages back to the patriarchal king-figure, Eri.[6] Eri's origins are unclear, though he has been described as a "sky being" sent by Chukwu (God).[6][7] He has been characterized as having first given societal order to the people of Anambra.[7]
Archaeological evidence suggests that Nri hegemony in Igboland may go back as far as the 9th century,[8] and royal burials have been unearthed dating to at least the 10th century. Eri, the god-like founder of Nri, is believed to have settled the region around 948 with other related Igbo cultures following after in the 13th century.[9] The first Eze Nri (King of Nri), Ìfikuánim, followed directly after him. According to Igbo oral tradition, his reign started in 1043.[10] At least one historian puts Ìfikuánim's reign much later, around 1225 AD.[11]
Each king traces his origin back to the founding ancestor, Eri. Each king is a ritual reproduction of Eri. The initiation rite of a new king shows that the ritual process of becoming Ezenri (Nri priest-king) follows closely the path traced by the hero in establishing the Nri kingdom.

—Elizabeth Allo Isichei[12]
The Kingdom of Nri was a religio-polity, a sort of theocratic state, that developed in the central heartland of the Igbo region.[9] The Nri had a taboo symbolic code with six types. These included human (such as the birth of twins), animal (such as killing or eating of pythons),[13] object, temporal, behavioral, speech and place taboos.[14] The rules regarding these taboos were used to educate and govern Nri's subjects. This meant that, while certain Igbo may have lived under different formal administration, all followers of the Igbo religion had to abide by the rules of the faith and obey its representative on earth, the Eze Nri.[13][14]
Decline of Nri kingdom[edit]
With the decline of Nri kingdom in the 1400-1600 AD, several states once under their influence, became powerful economic oracular oligarchies and large commercial states that dominated Igboland. The neighboring Awka city-state rose in power as a result of their powerful Agbala oracle and metalworking expertise. The Onitsha Kingdom, which was originally inhabited by Igbos from east of the Niger, was founded in the 16th century by migrants from Anioma (Western Igboland). Later groups like the Igala traders from the hinterland settled in Onitsha in the 18th century. Western Igbo kingdoms like Aboh, dominated trade in the lower Niger area from the 17th century until European penetration. The Umunoha state in the Owerri area used the Igwe ka Ala oracle at their advantage. However, the Cross River Igbo state like the Aro had the greatest influence in Igboland and adjacent areas after the decline of Nri. The Arochukwu kingdom which emerged after the Aro-Ibibio Wars from 1630 to 1720, and went on to form the Aro Confederacy which economically dominated Eastern Nigerian hinterland. The source of the Aro Confederacy's economic dominance was based on the judicial oracle of Ibini Ukpabi ("Long Juju") and their military forces which included powerful allies such as Ohafia, Abam, Ezza, and other related neighboring states. The related Abiriba (Abiriba and Aro Are Brothers whose migration is traced to Ekpa Kingdom in East of Cross River; their exact take of location was at Ekpa (Mkpa) east of the Cross river. They crossed the river to urupkam (Usukpam) west of the Cross river and founded two settlements: Ena Uda and Ena Ofia in present-day Erai. Aro and Abiriba cooperated to become a powerful economic force. Igbo gods, like those of the Yoruba, were numerous, but their relationship to one another and human beings was essentially egalitarian, reflecting Igbo society as a whole. A number of oracles and local cults attracted devotees while the central deity, the earth mother and fertility figure Ala, was venerated at shrines throughout Igboland. The weakness of a popular theory that Igbos were stateless rests on the paucity of historical evidence of pre-colonial Igbo society. There is a huge gap between the archaeological finds of Igbo Ukwu, which reveal a rich material culture in the heart of the Igbo region in the 8th century, and the oral traditions of the 20th century. Benin exercised considerable influence on the western Igbo, who adopted many of the political structures familiar to the Yoruba-Benin region, but Asaba and its immediate neighbors, such as Ibusa, Ogwashi-Ukwu, Okpanam, Issele-Azagba and Issele-Ukwu, were much closer to the Kingdom of Nri. Ofega was the queen for the Onitsha Igbo. Early states before 1500[edit]

Oyo and Benin[edit]
Main article: Oyo Empire
During the 15th century Oyo and Benin surpassed Ife as political and economic powers, although Ife preserved its status as a religious center. Respect for the priestly functions of the oni of Ife was a crucial factor in the evolution of Yoruban culture. The Ife model of government was adapted at Oyo, where a member of its ruling dynasty controlled several smaller city-states. A state council (the Oyo Mesi) named the alafin (king) and acted as a check on his authority. Their capital city was situated about 100 km north of present-day Oyo. Unlike the forest-bound Yoruba kingdoms, Oyo was in the savanna and drew its military strength from its cavalry forces, which established hegemony over the adjacent Nupe and the Borgu kingdoms and thereby developed trade routes farther to the north. The Benin Empire (1440–1897; called Bini by locals) was a pre-colonial African state in what is now modern Nigeria. It should not be confused with the modern-day country called Benin, formerly called Dahomey. Main article: Benin Empire
Northern kingdoms of the Sahel[edit]



The Songhai Empire, c. 1500
Trade is the key to the emergence of organized communities in the sahelian portions of Nigeria. Prehistoric inhabitants adjusting to the encroaching desert were widely scattered by the third millennium BC, when the desiccation of the Sahara began. Trans-Saharan trade routes linked the western Sudan with the Mediterranean since the time of Carthage and with the Upper Nile from a much earlier date, establishing avenues of communication and cultural influence that remained open until the end of the 19th century. By these same routes, Islam made its way south into West Africa after the 9th century AD. By then a string of dynastic states, including the earliest Hausa states, stretched across western and central Sudan. The most powerful of these states were Ghana, Gao, and Kanem, which were not within the boundaries of modern Nigeria but which influenced the history of the Nigerian savanna. Ghana declined in the 11th century but was succeeded by the Mali Empire which consolidated much of western Sudan in the 13th century. Following the breakup of Mali a local leader named Sonni Ali (1464–1492) founded the Songhai Empire in the region of middle Niger and the western Sudan and took control of the trans-Saharan trade. Sonni Ali seized Timbuktu in 1468 and Djenné in 1473, building his regime on trade revenues and the cooperation of Muslim merchants. His successor Askia Muhammad Ture (1493–1528) made Islam the official religion, built mosques, and brought Muslim scholars, including al-Maghili (d.1504), the founder of an important tradition of Sudanic African Muslim scholarship, to Gao.[15]
Although these western empires had little political influence on the Nigerian savanna before 1500 they had a strong cultural and economic impact that became more pronounced in the 16th century, especially because these states became associated with the spread of Islam and trade. Throughout the 16th century much of northern Nigeria paid homage to Songhai in the west or to Borno, a rival empire in the east. Kanem-Bornu Empire[edit]

Main article: Kanem-Bornu Empire
Borno's history is closely associated with Kanem, which had achieved imperial status in the Lake Chad basin by the 13th century. Kanem expanded westward to include the area that became Borno. The mai (king) of Kanem and his court accepted Islam in the 11th century, as the western empires also had done. Islam was used to reinforce the political and social structures of the state although many established customs were maintained. Women, for example, continued to exercise considerable political influence. The mai employed his mounted bodyguard and an inchoate army of nobles to extend Kanem's authority into Borno. By tradition the territory was conferred on the heir to the throne to govern during his apprenticeship. In the 14th century, however, dynastic conflict forced the then-ruling group and its followers to relocate in Borno, where as a result the Kanuri emerged as an ethnic group in the late 14th and 15th centuries. The civil war that disrupted Kanem in the second half of the 14th century resulted in the independence of Borno. Borno's prosperity depended on the trans-Sudanic slave trade and the desert trade in salt and livestock. The need to protect its commercial interests compelled Borno to intervene in Kanem, which continued to be a theater of war throughout the 15th century and into the 16th century. Despite its relative political weakness in this period, Borno's court and mosques under the patronage of a line of scholarly kings earned fame as centers of Islamic culture and learning. Hausa states[edit]

Main article: Hausa Kingdoms
By the 11th century some Hausa states - such as Kano, Jigawa, Katsina, and Gobir - had developed into walled towns engaging in trade, servicing caravans, and the manufacture of various goods. Until the 15th century these small states were on the periphery of the major Sudanic empires of the era. They were constantly pressured by Songhai to the west and Kanem-Borno to the east, to which they paid tribute. Armed conflict was usually motivated by economic concerns, as coalitions of Hausa states mounted wars against the Jukun and Nupe in the middle belt to collect slaves or against one another for control of trade. Islam arrived to Hausaland along the caravan routes. The famous Kano Chronicle records the conversion of Kano's ruling dynasty by clerics from Mali, demonstrating that the imperial influence of Mali extended far to the east. Acceptance of Islam was gradual and was often nominal in the countryside where folk religion continued to exert a strong influence. Nonetheless, Kano and Katsina, with their famous mosques and schools, came to participate fully in the cultural and intellectual life of the Islamic world. The Fulani began to enter the Hausa country in the 13th century and by the 15th century they were tending cattle, sheep, and goats in Borno as well. The Fulani came from the Senegal River valley, where their ancestors had developed a method of livestock management based on transhumance. Gradually they moved eastward, first into the centers of the Mali and Songhai empires and eventually into Hausaland and Borno. Some Fulbe converted to Islam as early as the 11th century and settled among the Hausa, from whom they became racially indistinguishable. There they constituted a devoutly religious, educated elite who made themselves indispensable to the Hausa kings as government advisers, Islamic judges, and teachers.

Savanna states[edit]
During the 16th century the Songhai Empire reached its peak, stretching from the Senegal and Gambia rivers and incorporating part of Hausaland in the east. Concurrently the Saifawa Dynasty of Borno conquered Kanem and extended control west to Hausa cities not under Songhai authority. Largely because of Songhai's influence, there was a blossoming of Islamic learning and culture. Songhai collapsed in 1591 when a Moroccan army conquered Gao and Timbuktu. Morocco was unable to control the empire and the various provinces, including the Hausa states, became independent. The collapse undermined Songhai's hegemony over the Hausa states and abruptly altered the course of regional history. Borno reached its pinnacle under mai Idris Aloma (ca. 1569-1600) during whose reign Kanem was reconquered. The destruction of Songhai left Borno uncontested and until the 18th century Borno dominated northern Nigeria. Despite Borno's hegemony the Hausa states continued to wrestle for ascendancy. Gradually Borno's position weakened; its inability to check political rivalries between competing Hausa cities was one example of this decline. Another factor was the military threat of the Tuareg centered at Agades who penetrated the northern districts of Borno. The major cause of Borno's decline was a severe drought that struck the Sahel and savanna from in the middle of the 18th century. As a consequence Borno lost many northern territories to the Tuareg whose mobility allowed them to endure the famine more effectively. Borno regained some of its former might in the succeeding decades, but another drought occurred in the 1790s, again weakening the state. Ecological and political instability provided the background for the jihad of Usman dan Fodio. The military rivalries of the Hausa states strained the region's economic resources at a time when drought and famine undermined farmers and herders. Many Fulani moved into Hausaland and Borno, and their arrival increased tensions because they had no loyalty to the political authorities, who saw them as a source of increased taxation. By the end of the 18th century, some Muslim ulema began articulating the grievances of the common people. Efforts to eliminate or control these religious leaders only heightened the tensions, setting the stage for jihad.[15]
According to the Encyclopedia of African History, "It is estimated that by the 1890s the largest slave population of the world, about 2 million people, was concentrated in the territories of the Sokoto Caliphate. The use of slave labor was extensive, especially in agriculture."[16]
Akwa Akpa[edit]

Main article: Akwa Akpa
The modern city of Calabar was founded in 1786 by Efik families who had left Creek Town, farther up the Calabar river, settling on the east bank in a position where they were able to dominate traffic with European vessels that anchored in the river, and soon becoming the most powerful in the region.[17] Akwa Akpa became a center of the slave trade, where slaves were exchanged for European goods.[18] Most slave ships that transported slaves from Calabar were English, and around 85% of these ships being from Bristol and Liverpool merchants.[19] The main ethnic group taken out of Calabar as slaves were the Igbo, although they were not the main ethnicity in the area.[20]
With the suppression of the slave trade, palm oil and palm kernels became the main exports. The chiefs of Akwa Akpa placed themselves under British protection in 1884.[21] From 1884 until 1906 Old Calabar was the headquarters of the Niger Coast Protectorate, after which Lagos became the main center.[21] Now called Calabar, the city remained an important port shipping ivory, timber, beeswax, and palm produce until 1916, when the railway terminus was opened at Port Harcourt, 145 km to the west.[22]
A British sphere of influence[edit]

Following the Napoleonic wars, the British expanded trade with the Nigerian interior. In 1885, British claims to a West African sphere of influence received international recognition; and in the following year, the Royal Niger Company was chartered under the leadership of Sir George Taubman Goldie. In 1900, the company's territory came under the control of the British Government, which moved to consolidate its hold over the area of modern Nigeria. On 1 January 1901, Nigeria became a British protectorate, part of the British Empire, the foremost world power at the time. In 1914, the area was formally united as the Colony and Protectorate of Nigeria. Administratively, Nigeria remained divided into the Northern and Southern Provinces and Lagos Colony. Western education and the development of a modern economy proceeded more rapidly in the south than in the north, with consequences felt in Nigeria's political life ever since. Following World War II, in response to the growth of Nigerian nationalism and demands for independence, successive constitutions legislated by the British Government moved Nigeria toward self-government on a representative and increasingly federal basis. On 1 October 1954, the colony became the autonomous Federation of Nigeria. By the middle of the 20th century, the great wave for independence was sweeping across Africa. On 27 October 1958 Britain agreed that Nigeria would become an independent state on 1 October 1960. Independence[edit]

Main article: History of Nigeria (1960-1979)


Jaja Wachuku, First Nigerian Speaker of the House, 1959-60
The Federation of Nigeria was granted full independence on 1 October 1960 under a constitution that provided for a parliamentary government and a substantial measure of self-government for the country's three regions. From 1959 to 1960, Jaja Wachuku was the First Nigerian Speaker of the Nigerian Parliament - also called the "House of Representatives." Jaja Wachuku replaced Sir Frederick Metcalfe of Britain. Notably, as First Speaker of the House, Jaja Wachuku received Nigeria's Instrument of Independence - also known as Freedom Charter - on 1 October 1960, from Princess Alexandra of Kent, The Queen's representative at the Nigerian independence ceremonies. The federal government was given exclusive powers in defense, foreign relations, and commercial and fiscal policy. The monarch of Nigeria was still head of state but legislative power was vested in a bicameral parliament, executive power in a prime minister and cabinet, and judicial authority in a Federal Supreme Court. Political parties, however, tended to reflect the make up of the three main ethnic groups. The Nigerian People's Congress (NPC) represented conservative, Muslim, largely Hausa and Fulani interests that dominated the Northern Region. The northern region of the country, consisting of three-quarters of the land area and more than half the population of Nigeria.[23] Thus the North dominated the federation government from the beginning of independence. In the 1959 elections held in preparation for independence, the NPC captured 134 seats in the 312-seat parliament.[23]
Capturing 89 seats in the federal parliament was the second largest party in the newly independent country the National Convention of Nigerian Citizens (NCNC). The NCNC represented the interests of the Igbo- and Christian-dominated people of the Eastern Region of Nigeria.[23] and the Action Group (AG) was a left-leaning party that represented the interests of the Yoruba people in the West. In the 1959 elections the AG obtained 73 seats.[23]
The first post-independence national government was formed by a conservative alliance of the NCNC and the NPC. Upon independence, it was widely expected that Ahmadu Bello the Sardauna of Sokoto, the undisputed strong man in Nigeria[24] who controlled the North, would become Prime Minister of the new Federation Government. However, Bello chose to remain as premier of the North and as party boss of the NPC, selected Sir Abubakar Tafawa Balewa, a Hausa, to become Nigeria's first Prime Minister. The Yoruba-dominated AG became the opposition under its charismatic leader Chief Obafemi Awolowo. However, in 1962, a faction arose within the AG under the leadership of Ladoke Akintola who had been selected as premier of the West. The Akintola faction argued that the Yoruba peoples were losing their pre-eminent position in business in Nigeria to people of the Igbo tribe because the Igbo-dominated NCNC was part of the governing coalition and the AG was not.[23] The federal government Prime Minister, Balewa agreed with the Akintola faction and sought to have the AG join the government. The party leadership under Awolowo disagreed and replaced Akintola as premier of the West with one of their own supporters. However, when Western Region parliament met to approve this change, Akintola supporters in the parliament started a riot in the chambers of the parliament.[25] Fighting between the members broke out. Chairs were thrown and one member grabbed the parliamentary Mace and wielded it like a weapon to attack the Speaker and other members. Eventually, the police with tear gas were required to quell the riot. In subsequent attempts to reconvene the Western parliament, similar disturbances broke out.[25] Unrest continued in the West and contributed to the Western Region's reputation for, violence, anarchy and rigged elections.[26] Federal Government Prime Minister Balewa declared martial law in the Western Region and arrested Awolowo and other members of his faction charged them with treason. Akintola was appointed to head a coalition government in the Western Region. Thus, the AG was reduced to an opposition role in their own stronghold.[25]
First Republic[edit]

Main article: Nigerian First Republic
In October 1963 Nigeria proclaimed itself the Federal Republic of Nigeria, and former Governor General Nnamdi Azikiwe became the country's first President. From the outset Nigeria's ethnic and religious tensions were magnified by the disparities in economic and educational development between the south and the north. The AG was maneuvered out of control of the Western Region by the Federal Government and a new pro-government Yoruba party, the Nigerian National Democratic Party (NNDP), took over. Shortly afterward the AG opposition leader, Chief Obafemi Awolowo, was imprisoned to be without foundation. The 1965 national election produced a major realignment of politics and a disputed result that set the country on the path to civil war.[27] The dominant northern NPC went into a conservative alliance with the new Yoruba NNDP, leaving the Igbo NCNC to coalesce with the remnants of the AG in a progressive alliance. In the vote, widespread electoral fraud was alleged and riots erupted in the Yoruba West where heartlands of the AG discovered they had apparently elected pro-government NNDP representatives. First period of military rule[edit]
Main article: Nigerian Civil War
On 15 January 1966 a group of army officers (the Young Majors) mostly south-eastern Igbos, overthrew the NPC-NNDP government and assassinated the prime minister and the premiers of the northern and western regions. However the bloody nature of the Young Majors coup caused another coup to be carried out by General Johnson Aguiyi-Ironsi. The Young Majors went into hiding. Major Emmanuel Ifeajuna fled to Kwami Nkrumah's Ghana where he was welcomed as a hero.[28] Some of the Young Majors were arrested and detained by the Ironsi government. Among the Igbo people of the Eastern Region, these detainees were heroes.[29] In the Northern Region, however, the Hausa and Fulani people demanded that the detainees be placed on trial for murder.[29] The federal military government that assumed power under General Johnson Aguiyi-Ironsi was unable to quiet ethnic tensions on issue or other issues. Additionally, the Ironsi government was unable to produce a constitution acceptable to all sections of the country.[30] Most fateful for the Ironsi government was the decision to issue Decree No. 34 which sought to unify the nation.[31] Decree No. 34 sought to do away with the whole federal structure under which the Nigerian government had been organized since independence. Rioting broke out in the North.[32] The Ironsi government's efforts to abolish the federal structure and the renaming the country the Republic of Nigeria on 24 May 1966 raised tensions and led to another coup by largely northern officers in July 1966, which established the leadership of Major General Yakubu Gowon.[33] The name Federal Republic of Nigeria was restored on 31 August 1966. However, the subsequent massacre of thousands of Igbo in the north prompted hundreds of thousands of them to return to the south-east where increasingly strong Igbo secessionist sentiment emerged. In a move towards greater autonomy to minority ethnic groups the military divided the four regions into 12 states. However the Igbo rejected attempts at constitutional revisions and insisted on full autonomy for the east. The Central Intelligence Agency commented in October 1966 in an CIA Intelligence Memorandum that:[34]
"Africa's most populous country (population estimated at 48 million) is in the throes of a highly complex internal crisis rooted in its artificial origin as a British dependency containing over 250 diverse and often antagonistic tribal groups. The present crisis started" with Nigerian independence in 1960, but the federated parliament hid "serious internal strains. It has been in an acute stage since last January when a military coup d'état destroyed the constitutional regime bequeathed by the British and upset the underlying tribal and regional power relationships. At stake now are the most fundamental questions which can be raised about a country, beginning with whether it will survive as a single viable entity. The situation is uncertain, with Nigeria, ..is sliding downhill faster and faster, with less and less chance unity and stability. Unless present army leaders and contending tribal elements soon reach agreement on a new basis for association and take some effective measures to halt a seriously deteriorating security situation, there will be increasing internal turmoil, possibly including civil war. A Biafra child suffering the effects of severe hunger and malnutrition as a result of the blockade. On 29 May 1967, Lt. Emeka Ojukwu, the military governor of the eastern region who emerged as the leader of increasing Igbo secessionist sentiment, declared the independence of the eastern region as the Republic of Biafra on 30 May 1967.[35] The ensuing Nigerian Civil War resulted in an estimated 3.5 million deaths (mostly from starving children) before the war ended with Gowon's famous "No victor, no vanquished" speech in 1970.[36]
Following the civil war the country turned to the task of economic development. The U.S. intelligence community concluded in November 1970 that "...The Nigerian Civil War ended with relatively little rancor. The Igbos were accepted as fellow citizens in many parts of Nigeria, but not in some areas of former Biafra where they were once dominant. Iboland is an overpopulated, economically depressed area where massive unemployment is likely to continue for many years.[37]
The U.S. analysts said that "...Nigeria is still very much a tribal society..." where local and tribal alliances count more than "national attachment. General Yakubu Gowon, head of the Federal Military Government (FMG) is the accepted national leader and his popularity has grown since the end of the war. The FMG is neither very efficient nor dynamic, but the recent announcement that it intends to retain power for six more years has generated little opposition so far. The Nigerian Army, vastly expanded during the war, is both the main support to the FMG and the chief threat to it. The troops are poorly trained and disciplined and some of the officers are turning to conspiracies and plotting. We think Gowon will have great difficulty in staying in office through the period which he said is necessary before the turnover of power to civilians. His sudden removal would dim the prospects for Nigerian stability." "Nigeria's economy came through the war in better shape than expected." Problems exist with inflation, internal debt, and a huge military budget, competing with popular demands for government services. "The petroleum industry is expanding faster than expected and oil revenues will help defray military and social service expenditures... "Nigeria emerged from the war with a heightened sense of national pride mixed with anti-foreign sentiment, and an intention to play a larger role in African and world affairs." British cultural influence is strong but its political influence is declining. The Soviet Union benefits from Nigerian appreciation of its help during the war, but is not trying for control. Nigerian relations with the US, cool during the war, are improving, but France may be seen as the future patron. "Nigeria is likely to take a more active role in funding liberation movements in southern Africa." Lagos, however, is not perceived as the "spiritual and bureaucratic capital of Africa"; Addis Ababa has that role...." Foreign exchange earnings and government revenues increased spectacularly with the oil price rises of 1973-74. On 29 July 29, 1975 Gen. Murtala Mohammed and a group of officers staged a bloodless coup, accusing Gen. Yakubu Gowon of corruption and delaying the promised return to civilian rule. General Mohammed replaced thousands of civil servants and announced a timetable for the resumption of civilian rule by 1 October 1979. He was assassinated on 13 February 1976 in an abortive coup and his chief of staff Lt. Gen. Olusegun Obasanjo became head of state. Second Republic[edit]

Main article: Nigerian Second Republic
A constituent assembly was elected in 1977 to draft a new constitution, which was published on 21 September 1978, when the ban on political activity was lifted. In 1979, five political parties competed in a series of elections in which Alhaji Shehu Shagari of the National Party of Nigeria (NPN) was elected president.[38] All five parties won representation in the National Assembly. During the 1950s prior to independence, oil was discovered off the coast of Nigeria. Almost immediately, the revenues from oil began to make Nigeria a wealthy nation. However, the spike in oil prices from $3 per barrel to $12 per barrel, following the Yom Kipur War in 1973 brought a sudden rush of money to Nigeria.[39] Another sudden rise in the price of oil in 1979 to $19 per barrel occurred as a result of the lead up to the Iran-Iraq War.[39] All of this meant that by 1979, Nigeria was the sixth largest producer of oil in the world with revenues from oil of $24 billiion per year.[38]
In August 1983, Shagari and the NPN were returned to power in a landslide victory with a majority of seats in the National Assembly and control of 12 state governments. But the elections were marred by violence and allegations of widespread vote rigging and electoral malfeasance, leading to legal battles over the results.[40]
On December 31, 1983 the military overthrew the Second Republic. Major General Muhammadu Buhari emerged as the leader of the Supreme Military Council (SMC), the country's new ruling body. The Buhari government was peacefully overthrown by the SMC's third-ranking member General Ibrahim Babangida in August 1985. Babangida (IBB) cited the misuse of power, violations of human rights by key officers of the SMC, and the government's failure to deal with the country's deepening economic crisis as justifications for the takeover. During his first days in office President Babangida moved to restore freedom of the press and to release political detainees being held without charge. As part of a 15-month economic emergency plan he announced pay cuts for the military, police, civil servants and the private sector. President Babangida demonstrated his intent to encourage public participation in decision making by opening a national debate on proposed economic reform and recovery measures. The public response convinced Babangida of intense opposition to an economic recession. The abortive Third Republic[edit]

Main article: Nigerian Third Republic
Head of State, Babangida, promised to return the country to civilian rule by 1990 which was later extended until January 1993. In early 1989 a constituent assembly completed a constitution and in the spring of 1989 political activity was again permitted. In October 1989 the government established two parties, the National Republican Convention (NRC) and the Social Democratic Party (SDP) - other parties were not allowed to register. In April 1990 mid-level officers attempted unsuccessfully to overthrow the government and 69 accused plotters were executed after secret trials before military tribunals. In December 1990 the first stage of partisan elections was held at the local government level. Despite low turnout there was no violence and both parties demonstrated strength in all regions of the country, with the SDP winning control of a majority of local government councils. In December 1991 state legislative elections were held and Babangida decreed that previously banned politicians could contest in primaries scheduled for August. These were canceled due to fraud and subsequent primaries scheduled for September also were canceled. All announced candidates were disqualified from standing for president once a new election format was selected. The presidential election was finally held on 12 June 1993, with the inauguration of the new president scheduled to take place 27 August 1993, the eighth anniversary of President Babangida's coming to power. In the historic 12 June 1993 presidential elections, which most observers deemed to be Nigeria's fairest, early returns indicated that wealthy Yoruba businessman M. O. Abiola won a decisive victory. However, on 23 June, Babangida, using several pending lawsuits as a pretense, annulled the election, throwing Nigeria into turmoil. More than 100 were killed in riots before Babangida agreed to hand power to an interim government on 27 August 1993. He later attempted to renege this decision, but without popular and military support, he was forced to hand over to Ernest Shonekan, a prominent nonpartisan businessman. Shonekan was to rule until elections scheduled for February 1994. Although he had led Babangida's Transitional Council since 1993, Shonekan was unable to reverse Nigeria's economic problems or to defuse lingering political tension. Sani Abacha[edit]
With the country sliding into chaos Defense Minister Sani Abacha assumed power and forced Shonekan's resignation on 17 November 1993. Abacha dissolved all democratic institutions and replaced elected governors with military officers. Although promising restoration of civilian rule he refused to announce a transitional timetable until 1995. Following the annulment of the June 12 election the United States and others imposed sanctions on Nigeria including travel restrictions on government officials and suspension of arms sales and military assistance Additional sanctions were imposed as a result of Nigeria's failure to gain full certification for its counter-narcotics efforts. Although Abacha was initially welcomed by many Nigerians, disenchantment grew rapidly. Opposition leaders formed the National Democratic Coalition (NADECO), which campaigned to reconvene the Senate and other disbanded democratic institutions. On 11 June 1994 Moshood Kashimawo Olawale Abiola declared himself president and went into hiding until his arrest on 23 June. In response petroleum workers called a strike demanding that Abacha release Abiola and hand over power to him. Other unions joined the strike, bringing economic life around Lagos and the southwest to a standstill. After calling off a threatened strike in July the Nigeria Labour Congress (NLC) reconsidered a general strike in August after the government imposed conditions on Abiola's release. On 17 August 1994 the government dismissed the leadership of the NLC and the petroleum unions, placed the unions under appointed administrators, and arrested Frank Kokori and other labor leaders. The government alleged in early 1995 that military officers and civilians were engaged in a coup plot. Security officers rounded up the accused, including former Head of State Obasanjo and his deputy, retired General Shehu Musa Yar'Adua. After a secret tribunal most of the accused were convicted and several death sentences were handed down. In 1994 the government set up the Ogoni Civil Disturbances Special Tribunal to try Ogoni activist Ken Saro-Wiwa and others for their alleged roles in the killings of four Ogoni politicians. The tribunal sentenced Saro-Wiwa and eight others to death and they were executed on 10 November 1995. On 1 October 1995 Abacha announced the timetable for a three-year transition to civilian rule. Only five political parties were approved by the regime and voter turnout for local elections in December 1997 was under 10%. On 21 December 1997 the government arrested General Oladipo Diya, ten officers, and eight civilians on charges of coup plotting. The accused were tried before a military tribunal in which Diya and eight others were sentenced to death. Abacha enforced authority through the federal security system which is accused of numerous human rights abuses, including infringements on freedom of speech, assembly, association, travel, and violence against women. Abubakar's transition to civilian rule[edit]
Abacha died of heart failure on 8 June 1998 and was replaced by General Abdulsalami Abubakar. The military Provisional Ruling Council (PRC) under Abubakar commuted the sentences of those accused in the alleged coup during the Abacha regime and released almost all known civilian political detainees. Pending the promulgation of the constitution written in 1995, the government observed some provisions of the 1979 and 1989 constitutions. Neither Abacha nor Abubakar lifted the decree suspending the 1979 constitution, and the 1989 constitution was not implemented. The judiciary system continued to be hampered by corruption and lack of resources after Abacha's death. In an attempt to alleviate such problems Abubakar's government implemented a civil service pay raise and other reforms. In August 1998 Abubakar appointed the Independent National Electoral Commission (INEC) to conduct elections for local government councils, state legislatures and governors, the national assembly, and president. The NEC successfully held elections on 5 December 1998, 9 January 1999, 20 February, and 27 February 1999, respectively. For local elections nine parties were granted provisional registration with three fulfilling the requirements to contest the following elections. These parties were the People's Democratic Party (PDP), the All People's Party (APP), and the predominantly Yoruba Alliance for Democracy (AD). Former military head of state Olusegun Obasanjo, freed from prison by Abubakar, ran as a civilian candidate and won the presidential election. The PRC promulgated a new constitution based largely on the suspended 1979 constitution, before the 29 May 1999 inauguration of the new civilian president. The constitution includes provisions for a bicameral legislature, the National Assembly consisting of a 360-member House of Representatives and a 109-member Senate. Fourth Republic[edit]

The emergence of democracy in Nigeria on May 1999 ended 16 years of consecutive military rule. Olusegun Obasanjo inherited a country suffering economic stagnation and the deterioration of most democratic institutions. Obasanjo, a former general, was admired for his stand against the Abacha dictatorship, his record of returning the federal government to civilian rule in 1979, and his claim to represent all Nigerians regardless of religion. The new President took over a country that faced many problems, including a dysfunctional bureaucracy, collapsed infrastructure, and a military that wanted a reward for returning quietly to the barracks. The President moved quickly and retired hundreds of military officers holding political positions, established a blue-ribbon panel to investigate human rights violations, released scores of persons held without charge, and rescinded numerous questionable licenses and contracts left by the previous regimes. The government also moved to recover millions of dollars in funds secreted to overseas accounts. Most civil society leaders and Nigerians witnessed marked improvements in human rights and freedom of the press under Obasanjo. As Nigeria works out representational democracy, conflicts persist between the Executive and Legislative branches over appropriations and other proposed legislation. A sign of federalism has been the growing visibility of state governors and the inherent friction between Abuja and the state capitals over resource allocation.[41]
Communal violence has plagued the Obasanjo government since its inception. In May 1999 violence erupted in Kaduna State over the succession of an Emir resulting in more than 100 deaths. In November 1999, the army destroyed the town of Odi, Bayelsa State and killed scores of civilians in retaliation for the murder of 12 policemen by a local gang. In Kaduna in February–May 2000 over 1,000 people died in rioting over the introduction of criminal Shar'ia in the State. Hundreds of ethnic Hausa were killed in reprisal attacks in south-eastern Nigeria. In September 2001, over 2,000 people were killed in inter-religious rioting in Jos. In October 2001, hundreds were killed and thousands displaced in communal violence that spread across the states of Benue, Taraba, and Nasarawa. On 1 October 2001 Obasanjo announced the formation of a National Security Commission to address the issue of communal violence. Obasanjo was reelected in 2003. The new president faces the daunting task of rebuilding a petroleum-based economy, whose revenues have been squandered through corruption and mismanagement. Additionally, the Obasanjo administration must defuse longstanding ethnic and religious tensions if it hopes to build a foundation for economic growth and political stability. Currently there is conflict in the Niger Delta over the environmental destruction caused by oil drilling and the ongoing poverty in the oil-rich region. A further major problem created by the oil industry is the drilling of pipelines by the local population in an attempt to drain off the petroleum for personal use or as a source of income. This often leads to major explosions and high death tolls.[42] Particularly notable disasters in this area have been: 1) October 1998, Jesse, 1100 deaths, 2) July 2000, Jesse, 250 deaths, 3) September 2004, near Lagos, 60 deaths, 4) May 2006, Ilado, approx. 150-200 deaths (current estimate).[43]
Two militants of an unknown faction shot and killed Ustaz Ja'afar Adam, a northern Muslim religious leader and Kano State official, along with one of his disciples in a mosque in Kano during dawn prayers on 13 April 2007. Obasanjo had recently stated on national radio that he would "deal firmly" with election fraud and violence advocated by "highly placed individuals." His comments were interpreted by some analysts as a warning to his Vice President and 2007 presidential candidate Atiku Abubakar.[44]
In the 2007 general election, Umaru Yar'Adua and Goodluck Jonathan, both of the People's Democratic Party, were elected President and Vice President, respectively. The election was marred by electoral fraud, and denounced by other candidates and international observers.[45][46]
Yar'Adua's sickness and Jonathan's successions[edit]

Yar'Adua's presidency was fraught with uncertainty as media reports said he suffered from kidney and heart disease. In November 2009, he fell ill and was flown out of the country to Saudi Arabia for medical attention. He remained incommunicado for 50 days, by which time rumours were rife that he had died. This continued until the BBC aired an interview that was allegedly done via telephone from the president's sick bed in Saudi Arabia. As of January 2010, he was still abroad. In February 2010, Goodluck Jonathan began serving as acting President in the absence of Yaradua.[47] In May 2010, the Nigerian government learned of Yar'Adua's death after a long battle with existing health problems and an undisclosed illness. This lack of communication left the new acting President Jonathan with no knowledge of his predecessor's plans. Yar'Adua's Hausa-Fulani background gave him a political base in the northern regions of Nigeria, while Goodluck does not have the same ethnic and religious affiliations. This lack of primary ethnic support makes Jonathan a target for militaristic overthrow or regional uprisings in the area. With the increase of resource spending and oil exportation, Nigerian GDP and HDI (Human Development Index) have risen phenomenally since the economically stagnant rule of Sani Abacha, but the primary population still survives on less than $2 USD per day. Goodluck Jonathan called for new elections and stood for re-election in April 2011. He won and is currently the president of Nigeria.[48][49]
Historiography[edit]

Main article: Ibadan School
The Ibadan School dominated the academic study of Nigerian history until the 1970s. It arose at the University of Ibadan in the 1950s and remained dominant until the 1970s. The University of Ibadan was the first university to open in Nigeria, and its scholars set up the history departments at most of Nigeria's other universities, spreading the Ibadan historiography. Its scholars also wrote the textbooks that were used at all levels of the Nigerian education system for many years. The school's output appears in the "Ibadan History Series."[50]
The leading scholars of the Ibadan School include Saburi Biobaku, Kenneth Dike, J. F. A. Ajayi, Adiele Afigbo, E. Ayandele, O. Ikime and Tekena Tamuno. Foreign scholars often associated with the school include Michael Crowder, Abdullahi Amith, J. B. Webster, R. J. Gavin, Robert Smith, and John D. Omer-Cooper. The school was characterized by its overt Nigerian nationalism and it was geared towards forging a Nigerian identity through publicizing the glories of pre-colonial history. The school was quite traditional in its subject matter, being largely confined to the political history that colleagues in Europe and North America were then rejecting. It was very modern, however, in the sources used. Much use was made of oral history and throughout the school took a strongly interdisciplinary approach to gathering information. This was especially true after the founding of the Institute for African Studies that brought together experts from many disciplines. The Ibadan School began to decline in importance the 1970s. The Nigerian Civil War led some to question whether Nigeria was in fact a unified nation with a national history. At the same time rival schools developed. At Ahmadu Bello University in Zaria, Nigeria, the Islamic Legitimist school arose that rejected Western models in favour of the scholarly tradition of the Sokoto Caliphate and the Islamic world. From other parts of Africa the Neo-Marxist school arrived and gained a number of supporters. Social, economic, and cultural history also began to grow in prominence. In the 1980s Nigerian scholarship in general began to decline, and the Ibadan School was much affected. The military rulers looked upon the universities with deep suspicion and they were poorly funded. Many top minds were co-opted with plum jobs in the administration and left academia. Others left the country entirely for jobs at universities in the West. The economic collapse of the 1980s also greatly hurt the scholarly community, especially the sharp devaluation of the Nigerian currency. This made inviting foreign scholars, subscribing to journals, and attending conferences vastly more expensive. Many of the domestic journals, including the Journal of the Historical Society of Nigeria, faltered and were only published rarely, if at all.[51]
