Lord Edward's Crusade
The last holy Crusade, sometimes called the Ninth Crusade, was an extension of the Eighth Crusade, lead by Lord Edward.
The result of the war is inconclusive; however, Jerusalem remained under Muslim control.
After the war, the Treaty of Caesarea was established, and there was a ten-year truce between Mamluks and Crusaders. (jan 1, 1271 – jan 1, 1272)
