In 1185, the last Byzantine governor of Cyprus, Isaac Komnenos, from a minor line of the Komnenos imperial house, rose in rebellion and attempted to seize the throne. His attempted coup was unsuccessful, but Komnenos was able to retain control of the island. Byzantine actions against Komnenos failed because he enjoyed the support of William II of Sicily. The emperor had agreed with the sultan of Egypt to close Cypriot harbours to the Crusaders.
