Suleyman

Süleyman vigorously promoted Ottoman expansion both in southwest Asia and in Europe. In 1534 he conquered Baghdad and added the Tigris and Euphrates valleys to the Ottoman domain. In Europe he kept the rival Habsburg empire on the defensive throughout his reign. He captured Belgrade in 1521, defeated and killed the king of Hungary at the battle of Mohács in 1526, consolidated Ottoman power north of the Danube, and in 1529 subjected the Habsburgs' prized city of Vienna to a brief but nonetheless terrifying siege.
