The Siege of Antioch took place during the First Crusade in 1097 and 1098. The first siege, by the crusaders against the Muslim-held city, lasted from 21 October 1097 to 2 June 1098. Antioch lay on the crusaders' route to Palestine, and anticipating that it would be attacked, the Muslim governor of the city, Yaghi-Siyan, began stockpiling food and sending requests for help. The Byzantine walls surrounding the city presented a formidable obstacle to its capture, so the leaders of the crusade decided to besiege Antioch.
