Süleyman Pasha (son of Orhan)

Traditional Ottoman historiography wrote that Süleyman Pasha's mother was Nilüfer Hatun, who was also the mother of Murad I.^[2] This has been refuted by modern historiography:^{[3][4][5][1][6]}Süleyman's mother was actually the consort Efendize Hatun, while Nilüfer entered the harem in 1325, twenty years after Süleyman's birth.^[1][7] Efendize was Orhan's cousin, the daughter of his uncle Gündüz Bey.^[8]

For his achievements as a warrior, Süleyman Pasha was given the title Ghazi.^[9][10]

He was one of Orhan's main generals, especially in Thrace, and became known as the "Conqueror of Rumelia".^[9][10]

He conquered Iznik (Nicaea) in 1331, Karesioğulları in 1335, and Izmit (Nicomedia) in 1337. His father appointed him governor of all his conquests. Between 1349 and 1354 he conquered Gallipoli and its region. He failed in the siege of Sofia, but he killed its governor Ivan Asen, son of tsar Ivan Alexander.^[9][10]

In 1355 he crossed the Dardanelles and conquered parts of Rumelia, where he created a nucleus of Ottoman settlements, including Bulair (Bolayır), Rodosto (Tekirdağ), Ipsala, and Malgara (Malkara), which were then exploited as a base for future conquests. In the same year, he killed a second son of Ivan Alexander, Michael.^[9][10]

He died in 1357, due to a fall from his horse while hunting with falcon between Bolayır and Seydikavağı.^[11] His father had him buried in Bolayır, even though Süleyman had already had a mausoleum built in Yenişehir, near Bursa.^[11]

He is also remembered for his religious and charitable constructions in the territories he administered: he built mosques, madrasas, caravanserais and schools in Bursa, Göynük, Geyve, Akyazı, İzmit, İznik and Gelibolu.^[10]
