Prior to the Siege of Antioch, most Armenians were expelled from Antioch by the Turkish governor of the city Yaghi-Siyan, a move that prompted the Armenians of Antioch, and the rulers of the Armenian Kingdom of Cilicia to establish close relations with the European Crusades rather than the mostly-Turkish rulers of Syria. Thus, the new rulers of Antioch became the Europeans. Armenian engineers also helped the Crusaders during the Siege of Tyre by manipulating siege engines.
