Timur makes Samarkand his capital

Timur (Tamerlane) seized power in 1370 and made Samarkand the capital of an empire won by conquest from Delhi to Anatolia, bringing captured craftsmen to build the Bibi-Khanym mosque and his own tomb, the Gur-e-Amir. His grandson Ulugh Beg ruled the city as a centre of learning, building a madrasa on the Registan and an observatory whose star tables were the most accurate of their age.
