Battle context
The Siege of Antioch was a pivotal episode in the First Crusade, deciding control of one of the most strategically significant cities on the route from Constantinople to Jerusalem. The Crusaders invested the Seljuk-held city for more than seven months before taking it in June 1098. Control of Antioch was not secured until a second phase: a Seljuk relieving army under Kerbogha then besieged the Crusaders inside the city for three weeks, and the subsequent Battle of Antioch ended in a Crusader victory over that force. The outcome removed a major Seljuk presence from northern Syria and opened the road south toward Jerusalem. Beyond its operational consequences, the siege produced a lasting political result: Bohemond of Taranto claimed the city and established the Principality of Antioch, one of the Crusader states that would define Latin political power in the Levant for generations. The siege thus shaped both the military trajectory of the First Crusade and the territorial order that followed it.
