Following the sack of Constantinople by crusaders and the Mongols’ defeat of the Seljuk Turks, the Ottomans emerged as a power in northwestern Anatolia. Under Osman’s successors, they crossed the Dardanelles into Europe, defeating the Serbs at the Battle of Kosovo. When the Mongol conqueror Timur invaded the region, he defeated Bayezid, and the subsequent conflict among Bayezid’s sons splintered the Ottoman state. Timur’s empire came to include Persia, central Asia, and northern India, but Timur died before he could fulfill his plan to invade China. Bayezid’s son Mehmed I and his grandson Murad II rebuilt Ottoman possessions in Anatolia and Europe. In 1453, among other victories, Mehmed II conquered Constantinople. He rebuilt the city, thereafter known as Istanbul, and invited scholars and artists from Asia and Europe. He was tolerant of his non-Muslim and European subjects and allowed them to remain in Istanbul, though historians see the flight of many scholars to western Europe with the preserved knowledge of ancient Greece and Rome as one factor that helped to spark the Italian Renaissance and the transition to the early modern era. Meanwhile, western European traders began to seek all-water, oceanic routes to South and East Asia.
