Küçük Mustafa
Küçük Mustafa was an Ottoman prince who fought to gain control of the throne of the Ottoman Empire in 1422. It was used by the Ottoman chroniclers to distinguish him from his uncle Mustafa Çelebi, who also fought for the throne.
Background
Mustafa was born in 1408. He was the second son of Mehmed I. In the early years of the Ottoman Empire, all princes were required to work as provincial governors as a part of their training. Young princes were accompanied by experienced statesmen. Mustafa's sanjak was Hamideli. But after the death of his father, fearing for his life at the hands of his elder brother, he escaped to the rival Turkish beylik Karamanid territory. In Karaman, he was encouraged by an Ottoman pasha named Şaraptar İlyas to rebel against his elder brother, new sultan Murad II.Mustafa was supported by the Byzantine Empire and married into the imperial family. In 1421 or 1422 he married Zampia [Palaiologina Doria], daughter of Zampia Palaiologina who in turn was an illegitimate daughter of Emperor John V Palaiologos.
