After Byzantine conquest of Bulgaria, the Cometopuli assumed important positions in the Byzantine court after they were resettled and given lands in Asia Minor and Armenia. Catherine, daughter of Bulgarian Emperor Ivan Vladislav, became empress of Byzantium. Peter II Delyan, son of Bulgarian Emperor Gavril Radomir and grandson of Emperor Samuel, led an attempt to restore the Bulgarian Empire after a major uprising in 10401041. Two other women of the dynasty became Byzantine empresses, while many nobles served in the army as strategos or became governors of various provinces. Through his maternal grandmother Maria of Bulgaria, the Byzantine emperor John II Komnenos was a descendant of Emperor Ivan Vladislav.
