Third Crusade: Saladin's garrison surrenders to Philip Augustus, ending the two-year siege of Acre.
The siege of Acre was the first significant counterattack by Guy of Jerusalem against Saladin, leader of the Muslims in Syria and Egypt. This pivotal siege 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.
The Third Crusade (1189–1192) was an attempt by three European monarchs of Western Christianity (Philip II of France, Richard I of England and Frederick I, Holy Roman Emperor) to reconquer the Holy Land following the capture of Jerusalem by the Ayyubid sultan Saladin in 1187. For this reason, the Third Crusade is also known as the Kings' Crusade.It was partially successful, recapturing the important cities of Acre and Jaffa, and reversing most of Saladin's conquests, but it failed to recapture Jerusalem, which was the major aim of the Crusade and its religious focus.
After the failure of the Second Crusade of 1147–1149, the Zengid dynasty controlled a unified Syria and engaged in a conflict with the Fatimid rulers of Egypt. Saladin ultimately brought both the Egyptian and Syrian forces under his own control, and employed them to reduce the Crusader states and to recapture Jerusalem in 1187. Spurred by religious zeal, King Henry II of England and King Philip II of France (known as "Philip Augustus") ended their conflict with each other to lead a new crusade. The death of Henry (6 July 1189), however, meant the English contingent came under the command of his successor, King Richard I of England.
The elderly German Emperor Frederick Barbarossa also responded to the call to arms, leading a massive army across the Balkans and Anatolia. He achieved some victories against the Seljuk Sultanate of Rûm, but he drowned in a river on 10 June 1190 before reaching the Holy Land. His death caused tremendous grief among the German Crusaders, and most of his troops returned home.
After the Crusaders had driven the Muslims from Acre, Philip—in company with Frederick's successor in command of the German crusaders, Leopold V, Duke of Austria—left the Holy Land in August 1191. Following a major victory by the Crusaders at the Battle of Arsuf, most of the coastline of the Levant was returned to Christian control. On 2 September 1192 Richard and Saladin finalized the Treaty of Jaffa, which recognised Muslim control over Jerusalem but allowed unarmed Christian pilgrims and merchants to visit the city. Richard departed the Holy Land on 9 October 1192. The successes of the Third Crusade allowed Westerners to maintain considerable states in Cyprus and on the Syrian coast.
The failure to re-capture Jerusalem inspired the subsequent Fourth Crusade of 1202–1204, but Europeans would only regain the city—and only briefly—in the Sixth Crusade in 1229.
