With Manuel's death in 1180 the Byzantine empire was once again plunged into a succession crisis because his son Alexios II Komnenos was still a minor. Empress Maria ruled the empire as regent, but she was quickly deposed by a series of revolts, and in her place Andronikos I became emperor. Andronikos was known for his incredible cruelty; he often utilized great acts of violence to get others to follow his orders, engendering little sympathy from the common people. Though Andronikos worked tirelessly to root out corruption in the Empire, his heavy-handed tactics against the aristocracy naturally led to dissent, and he was eventually overthrown in 1185.
