The Unratified Treaty between the Mamlūks and the Franks of Acre in 1268

In 1268, after negotiations with Baybars, King Hugh III rejected several of the sultan's terms and did not take the oath to confirm a truce. Baybars' biographer underplayed the refusal, claiming that Hugh's fear of Charles of Anjou prevented him from making a truce. Based on historical and archaeological evidence, this study draws the borders with the Mamlūks and the inner borders between the Frankish regions in 1268, 1272 and 1283, proving that the Frankish areas in 1268 were reduced to almost half of those that obtained in 1272 and 1283. Thus, this study assumes that Hugh could not have take the oath on terms that, inter alia, reduced the Frankish area to an unacceptable size. The Franks seem to have controlled more territory than they were given in the proposed 1268 treaty and it seems that Baybars' lack of interest in an attack on Acre encouraged the king to reject the truce.
