Transformation of the Ottoman Empire
Sultan Suleiman I (r. 1520–1566) was the longest-reigning sultan in Ottoman history, but the last years of his reign were characterized by uncertainty over who would be his successor. Suleiman had three sons who could hope to succeed, Mustafa, Bayezid, and Selim. While the latter two were the children of Suleiman's wife Hurrem Sultan, the first was the son of an earlier concubine. Mustafa may have felt that his half-brothers possessed an unfair advantage over him, and thus worked to secure the favor of the military. Perhaps suspecting that Mustafa planned to dethrone him just as his own father had done to his grandfather, Suleiman acted first and in 1553 ordered that Mustafa be executed. The death of Hurrem Sultan in 1558 triggered open conflict between the two remaining candidates, and Selim ultimately emerged victorious. Suleiman further strengthened his son's position by arranging a marriage between Selim's daughter and the influential Sokollu Mehmed Pasha (Grand Vizier 1565–1579). Suleiman died in 1566, while besieging the fortress of Szigetvar in Hungary, bringing Selim to the throne.
Suleiman the Magnificent
Suleiman had several children with his consorts, including:
Suleiman was infatuated with Hürrem Sultan, a harem girl from Ruthenia, then part of Poland. Western diplomats, taking notice of the palace gossip about her, called her "Russelazie" or "Roxelana", referring to her Ruthenian origins. The daughter of an Orthodox priest, she was captured by Tatars from Crimea, sold as a slave in Constantinople, and eventually rose through the ranks of the Harem to become Suleiman's favorite. Breaking with two centuries of Ottoman tradition, a former concubine had thus become the legal wife of the Sultan, much to the astonishment of the observers in the palace and the city. He also allowed Hürrem Sultan to remain with him at court for the rest of her life, breaking another tradition—that when imperial heirs came of age, they would be sent along with the imperial concubine who bore them to govern remote provinces of the Empire, never to return unless their progeny succeeded to the throne.
