The fall of Tripoli

27 Apr 1289 — Sultan Qalawun storms the county’s capital and levels it; the survivors are killed or enslaved as they flee to an offshore island. Only Acre now remains. A site of memory.

THE MOMENT IN CONTEXT

The instrument of Outremer’s end was, once again, a slave-soldier state, and its rise ran through two great shocks. At La Forbie near Gaza in 1244 an allied Frankish and Damascene army was destroyed by Egyptian forces and the Khwarezmian mercenaries who had just sacked Jerusalem, and this was the last time the crusader states fielded an army of any real size. Then the Mongols swept in, extinguishing Baghdad and the Abbasid caliphate, until at Ain Jalut in 1260 the Mamluks of Egypt halted them in Galilee. That victory did more than save the region, because it forged a disciplined, self-renewing military state, built on a slave-soldier system the Muslim world had used for centuries, that could now turn methodically against the crusader coast.

From Chapter 11 — Baibars and the End of The Crusades, 1095–1291 (1271).
