Huseyin Gazi is a warrior-saint (gazi) believed to have been martyred fighting the Byzantines during the Islamization of Anatolia; folk tradition names him the father of Battal Gazi and a seyyid. His historicity is largely legendary and the sources conflict. His tomb atop Huseyingazi Hill in Mamak originated as a 13th-century lodge, was repaired in 1378 and again under Mehmed the Conqueror (1463). (Sources: Mamak District Governorate; Kultur Envanteri.)
