Siege of Acre (1189–1191) siege in 1189-1191

The Siege of Acre was the first significant counterattack by King Guy of Jerusalem to the losses the kingdom experienced to Saladin, leader of the Muslims in Syria and Egypt and formed part of what later became known as the Third Crusade. The siege lasted from August 1189 until July 1191, in which time the city's coastal position meant the attacking Latin force were unable to fully invest the city and Saladin was unable to fully relieve it with both sides receiving supplies and resources by sea. Finally, it was a key victory for the Crusaders and a serious setback for Saladin's ambition to destroy the Crusader States.


After his third marriage, he sought to reclaim his wife's lands of Luxembourg, Durbuy and Laroche with the approval of Philip of Swabia. [4] Theobold therefore besieged the castle at Namur, whereupon a conference was held in which Philip of Namur and his brother Baldwin renounced the disputed territories of Luxembourg, Durbuy and Laroche. [4] The Treaty of Dinant signed 6 July 1199 at Saint Medard, later made it official. [4]
