The Duchy of Antioch was a Byzantine territory ruled by a duke (dux) appointed by and under the authority of the emperor. It was founded in 969 after the reconquest of Antioch by imperial troops and existed until December 1084, when Suleiman ibn Qutalmish (r. 1077–1086) of the Sultanate of Rum conquered the ducal capital.
