Timur

Bayezid I (r. 1389–1402), known as Yıldırım (the Thunderbolt) for his swift military campaigns, dramatically expanded the Ottoman state across the Balkans and Anatolia before his catastrophic defeat at the Battle of Ankara in 1402. His reign represents both the zenith of early Ottoman expansion and the fragility of a rapidly assembled empire when confronted by Timur's world-conquering forces.

Samarkand, one of Central Asia's oldest cities, was a major Silk Road hub, a center of early Islamic learning, and the capital of Timur's empire. Under the Timurid ruler Ulugh Beg it became a scientific capital, home to an observatory that produced the era's finest star catalog.

Timur (1336-1405 CE), known in the West as Tamerlane, was a Turco-Mongol conqueror who founded the Timurid Empire, creating one of the largest empires in history through his military campaigns across Central Asia, Persia, and India.
