Modern-day Jordan has been inhabited by humans since the Paleolithic period. Three stable kingdoms emerged there at the end of the Bronze Age: Ammon, Moab and Edom. Later rulers include the Assyrian Empire, Babylonian Empire, Nabataean Kingdom, the Persian Empire, the Roman Empire, including the latter Byzantine Empire, the Rashidun, Umayyad, and Abassid caliphates, and the Ottoman Empire. After the Great Arab Revolt against the Ottomans in 1916 during World War I, the Ottoman Empire was partitioned by Britain and France. The Emirate of Transjordan was established in 1921 by the Hashemite, then Emir, Abdullah I, and the emirate became a British protectorate. In 1946, Jordan became an independent state officially known as the Hashemite Kingdom of Transjordan, but it was renamed in 1949 to the Hashemite Kingdom of Jordan after the country captured the West Bank during the 1948 Arab–Israeli War and annexed it until it was lost to Israel in 1967. Jordan renounced its claim to the territory in 1988, and became the second Arab state to sign a peace treaty with Israel in 1994.[11] Jordan is a founding member of the Arab League and the Organisation of Islamic Co-operation. The sovereign state is a constitutional monarchy, but the king holds wide executive and legislative powers.
