The fall of Acre
18 May 1291 — the last great city of Outremer falls tower by tower after six weeks of siege; the final defenders drown or die on the mole. Two centuries of crusader rule on the mainland end in a single morning. A site of memory.
THE MOMENT IN CONTEXT
The instrument of the end is, once again, a slave-soldier state. At La Forbie near Gaza in 1244, an allied Frankish and Damascene army is destroyed by Egyptian forces and the Khwarezmians who had just sacked Jerusalem — the last time Outremer fields an army of any size. Then the Mongols come, sweeping away Baghdad and the Abbasid caliphate; and at Ain Jalut in 1260 the Mamluks of Egypt halt the seemingly invincible Mongols in Galilee. That victory saves the Islamic heartland — and forges a disciplined, self-renewing military state (the same slave-soldier system the Muslim world had used for centuries) that will now turn methodically on the crusader coast.
From Chapter 11 — Baibars and the End of The Crusades, 1095–1291 (1271).
