Koca Mustafa Pasha (Turkish, Ottoman (1500-1928);: كودجا مصطفى باشا; died 1512) was an Ottoman statesman. He was grand vizier of the Ottoman Empire from 1511 to 1512.[1] He was Roman (Rum) and probably not a devşirme.[2]
He started his career as kapıcıbaşı, that is "chief doorkeeper" of the Topkapi Palace: in this office he acted also as Master of Ceremonies at receptions of foreign ambassadors. He married a daughter of Sultan Bayezid II, Kamerşah Sultan, in 1491 and by her he had a daughter, Hundi Hanımsultan, and a son, Sultanzade Osman Bey. Appointed Grand Vizier near the end of the reign of Bayezid II, he was executed in 1512.[3] In Istanbul he let convert into mosques two ancient Byzantine churches, which were both named after him: respectively Koca Mustafa Pasha and Atik Mustafa Pasha Mosque.[4] [5]
