Siege and Fall of Acre

The Siege and Fall of Acre in 1291 brought the last major mainland centre of the Crusader states under Mamluk control. Acre was a fortified Mediterranean port containing merchants, military orders, pilgrims, refugees and rival political communities whose interests had made coordinated defence difficult.

Sultan al-Ashraf Khalil assembled a large army and siege train against the city in April. Bombardment, mining and repeated assaults broke the outer defences, and the final attack on 18 May produced street fighting, flight by sea and heavy loss of life. The surviving military orders withdrew from their remaining mainland positions soon afterwards.

As a child of the Crusader States context, Acre’s fall marks the collapse of the political and military system established after the First Crusade.
