The Turko-Mongol tradition was an ethnocultural synthesis that arose in Asia during the 14th century, among the ruling elites of the Golden Horde and the Chagatai Khanate. The ruling Mongol elites of these Khanates eventually assimilated into the Turkic populations that they conquered and ruled over, thus becoming known as Turco-Mongols. These elites gradually adopted Islam (from previous religions such as Tengrism) as well as Turkic languages, while retaining Mongol political and legal institutions.The Turco-Mongols founded many Islamic successor states after the collapse of the Mongol Khanates, such as the Kazakh Khanate and Tatar Khanates that succeeded the Golden Horde (e.g., Khanate of Crimea, Astrakhan Khanate, Kazan Khanate) and the Timurid Empire, which succeeded the Chagatai Khanate in Central Asia. Babur (1483–1530), a Turco-Mongol prince and a great-great-great-grandson of Timur, founded the Mughal Empire, which ruled almost all of the Indian subcontinent. The Turks and Tatars also ruled part of Egypt, exercising political and military authority during the Mamluk Sultanate.These Turco-Mongol elites became patrons of the Turco-Persian tradition, which was the predominant culture amongst the Muslims of Central Asia at the time. In subsequent centuries, the Turco-Persian culture was carried on further by the conquering Turco-Mongols to neighbouring regions, eventually becoming the predominant culture of the ruling and elite classes of South Asia (Indian subcontinent), specifically North India (Mughal Empire), Central Asia and the Tarim Basin (Northwest China) and large parts of West Asia (Middle East).
