Third Crusade

The Third Crusade (1189–1192) was an attempt led by King Philip II of France, King Richard I of England, and Emperor Frederick Barbarossa 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.

The Crusade was partially successful. It recaptured the important cities of Acre and Jaffa, as well as successfully reversing most of Saladin's conquests (primarily in the Kingdom of Jerusalem), but failed in the ultimate goal to conquer Jerusalem (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 (later 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 German Emperor Frederick Barbarossa, now in his mid-60s, also responded to the call to arms, leading an army across the Balkans and Anatolia. He achieved some victories against the Seljuk Sultanate of Rûm, but he died whilst crossing 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 Ayyubid army 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 recognized Muslim control over Jerusalem but allowed unarmed Christian pilgrims and merchants to visit the city. Richard departed the Holy Land on 9 October 1192 due to mounting threats to his rule back in Europe. The military successes of the Third Crusade allowed the Christians to maintain considerable states in Cyprus and on the Syrian coast, restoring the Kingdom of Jerusalem on a narrow strip from Tyre to Jaffa.

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.
