Classical Age of the Ottoman Empire
Expansion continued during the first half of the reign of Suleiman I (r. 1520-1566), who conquered first Belgrade (1521) and Rhodes, before invading Hungary in 1526, defeating and killing King Louis II in the Battle of Mohács and briefly occupying Buda. Lacking a king, Hungary descended into civil war over the succession, and the Ottomans gave support to John Zápolya as a vassal prince. When their rivals the Habsburgs began to achieve the upper hand, Suleiman directly intervened by again conquering Buda and annexing it to the empire in 1541. Elsewhere, Suleiman led major campaigns against Safavid Iran, conquering Baghdad in 1534 and annexing Iraq. Ottoman rule was further extended with the incorporation of much of North Africa, the conquest of coastal Yemen in 1538, and the subsequent annexation of the interior.
Sumu-abum
Sumu-Abum (also Su-abu) was an Amorite, and the first King of the First Dynasty of Babylon (the "Amorite Dynasty"). He reigned from 1830-1817 BC (middle chronology). He freed a small area of land previously ruled by the fellow Amorite city state of Kazallu which included Babylon, then a minor administrative center in southern Mesopotamia. Sumu-Abum (and the three Amorite kings succeeding him) makes no claim to be "King of Babylon", suggesting that the town was at this time still of little importance.
