In the 14th century much of Central Asia, and many areas beyond it, were conquered by Timur (1336–1405) who is known in the west as Tamerlane. It was during Timur's reign that the nomadic steppe culture of Central Asia fused with the settled culture of Iran. One of its consequences was an entirely new visual language that glorified Timur and subsequent Timurid rulers. This visual language was also used to articulate their commitment to Islam. Timur's large empire collapsed soon after his death, however. The region then became divided among a series of smaller Khanates, including the Khanate of Khiva, the Khanate of Bukhara, the Khanate of Kokand, and the Khanate of Kashgar.
