The territory of Kazakhstan has historically been inhabited by nomadic groups and empires. In antiquity, the ancient Iranian nomadic Scythians inhabited the land, and the Achaemenid Persian Empire expanded towards the southern territory of the modern country. Turkic nomads, who trace their ancestry to many Turkic states such as the First Turkic Khaganate and the Second Turkic Khaganate, have inhabited the country from as early as the 6th century. In the 13th century, the territory was subjugated by the Mongol Empire under Genghis Khan. In the 15th century, the Kazakh Khanate conquered much land that would later form the territory of modern Kazakhstan.
