Turco-Mongol conquests: Kara-Khanid Khanate (999–1212)

In 999 the Samanid Empire was conquered by an Islamic Turkic power, the Kara-Khanid Khanate (840–1212).

From 1212, the Kara-Khanids in Samarkand were conquered by the Kwarazmians. Soon however, Khwarezmia was invaded by the early Mongol Empire and its ruler Genghis Khan destroyed the once vibrant cities of Bukhara and Samarkand. However, in 1370, Samarkand saw a revival as the capital of the Timurid Empire. The Turko-Mongol ruler Timur brought about the forced immigration to Samarkand of artisans and intellectuals from across Asia, transforming it not only into a trade hub but also into one of the most important cities of the Islamic world.
