In 1370, Timur (Tamerlane), a Turkic-Mongol warlord claiming descent from Genghis Khan's lineage, seized Samarkand and declared himself sovereign of the former Chagatai Khanate. Over the following three decades he conquered an empire stretching from Anatolia to India, devastating cities from Damascus to Delhi. Despite the destruction, Timur transformed Samarkand into a center of art, architecture, and scholarship, forcibly relocating artisans from conquered cities to embellish his capital. The Registan and Bibi-Khanym Mosque date from this period. The Timurid Renaissance that followed produced advances in astronomy, miniature painting, and Persian literature.
