August 1290 · Acre
Killing of Muslim merchants at Acre
In August 1290, undisciplined crusaders who had come to Acre from northern Italy in answer to Pope Nicholas IV's call attacked Muslim merchants and peasants in the city despite the truce; some local Christians were also killed because, being bearded, they were taken for Muslims. When Qalawun's demand that the culprits be handed over was refused, the sultan began preparing for war.

Historical analysis of the event
Background
After the fall of Tripoli, Acre relied on the truce made with Qalawun in 1283, and the city traded heavily with Mamluk lands. Pope Nicholas IV called for help to defend the Holy Land; in response, a group from Lombardy and Tuscany, mostly inexperienced peasants and townsmen, reached Acre with a Venetian fleet in summer 1290.
Course of events
Unpaid and failing to understand the peaceful atmosphere in Acre, the newcomers attacked Muslim merchants and peasants who had brought produce to the city in August 1290. In the attacks some local Christians were also killed because, being bearded, they were taken for Muslims.
The city authorities and the military orders tried to stop the violence and arrested some of the attackers. Qalawun demanded that the culprits be handed over to him for punishment. In Acre's council, the Templar master William of Beaujeu's proposal to meet this demand was not accepted; the city authorities offered excuses, claiming that the dead had been killed in the Muslim merchants' own quarrels.
Outcome and significance
Declaring the truce broken, Qalawun began preparing a great campaign against Acre. The episode became the direct pretext for the fall of Acre.
The case is a tragic example of how crusading forces from the West failed to understand the local diplomatic balance in the Latin East, and how undisciplined violence could affect the fate of a whole society.
Sources and debates
The Templar of Tyre is the most detailed Latin narrator of the events and stresses William of Beaujeu's moderate stance. Mamluk sources, especially Abu al-Fida and Baybars al-Mansuri, present the episode as the legitimate justification for the campaign against Acre. The number killed and the scale of the attack differ between sources.
