Editing Eighth Crusade (section)

===The siege of Antioch===
The loss of Cilician Armenia in 1266 isolated Antioch and Tripoli, led by Hethum's son-in-law Bohemond VI, and Baibars continued the extermination of remaining Crusader garrisons in the following years.{{sfn|Bouchier|1921|pp=268–270|loc=Invasion of Sultan Baibars}} In 1268, Baibars laid siege to [[Jaffa#Mamluk period|Jaffa]], which belonged to [[Guy of Ibelin (died 1304)|Guy of Ibelin]], the son of the jurist [[John of Ibelin (jurist)|John of Ibelin]]. Jaffa fell on 7 March 1268 after twelve hours of fighting. Most of Jaffa's citizens were slain, but Baibars allowed the garrison to go unharmed. From there he proceeded to the seat of the principality and began the [[Siege of Antioch (1268)|Siege of Antioch]]. The Antiochene knights and garrison were under the command of the constable of Antioch, [[Simon Mansel]]. The city was captured on 18 May 1268. Baibars had yet again promised to spare the lives of the inhabitants, but he broke his promise and had the city razed, killing or enslaving much of the population after the surrender. The loss prompted the fall of the Principality of Antioch. The massacre of men, women, and children at Antioch "was the single greatest massacre of the entire Crusading era."{{sfn|Madden|2005|p=168|loc=Siege of Antioch}} Priests had their throats slit inside their churches, and women and children sold into slavery. As many as seventeen thousand Christians were slaughtered, and a hundred thousand dragged away into slavery.{{sfn|Runciman|1954|pp=324–325|loc=The Fall of Antioch, 1268}}
