for 'his passion for two of his slaves: for his beloved Ibrahim when the sultan was a hot-blooded youth, and for his beloved Hurrem when he was mature.' Ibrahim was originally a Christian from Parga (in Epirus), who was captured in a raid during the 1499–1503 Ottoman–Venetian War, and was given as a slave to Suleiman most likely in 1514. Ibrahim converted to Islam and Suleiman made him the royal falconer, then promoted him to first officer of the Royal Bedchamber. It was reported that they slept together in the same bed. The sultan also built Ibrahim a lavish palace on the ancient Hippodrome, Istanbul's main forum outside the Hagia Sophia and Topkapı Palace. Despite his following marriage and his new sumptuous residence, Ibrahim sometimes spent the night with Suleiman I at Topkapı Palace. In turn, the sultan occasionally slept at Ibrahim's lodgings. Ibrahim Pasha rose to Grand Vizier in 1523 and commander-in-chief of all the armies. Suleiman also conferred upon Ibrahim Pasha the honor of beylerbey of Rumelia (first-ranking military governor-general), granting Ibrahim authority over all Ottoman territories in Europe, as well as command of troops residing within them in times of war. At the time, Ibrahim was only about thirty years old and lacked any actual military expertise; it is said that 'tongues wagged' at this unprecedented promotion straight from palace service to the two highest offices of the empire. During his thirteen years as Grand Vizier, his rapid rise to power and vast accumulation of wealth had made Ibrahim many enemies at the Sultan's court. Suleiman's suspicion of Ibrahim was worsened by a quarrel between the latter and the finance secretary (defterdar) İskender Çelebi. The dispute ended in the disgrace of Çelebi on charges of intrigue, with Ibrahim convincing Suleiman to sentence the defterdar to death. Ibrahim also supported Şehzade Mustafa as the successor of Suleiman. This caused disputes between him and Hürrem Sultan, who wanted her sons to succeed to the throne. Ibrahim eventually fell from grace with the Sultan and his wife. Suleiman consulted his Qadi, who suggested that Ibrahim be put to death. The Sultan recruited assassins and ordered them to strangle Ibrahim in his sleep. Succession Sultan Suleiman's two known consorts (Hürrem and Mahidevran) had borne him six sons, four of whom survived past the 1550s. They were Mustafa, Selim, Bayezid, and Cihangir. Of these, the eldest was not Hürrem's son, but rather
