Holy Roman Emperor Frederick I Barbarossa and 100,000 crusaders depart Regensburg for the Third Crusade on May 11, 1189. The Crusade was led by three European monarchs of Western Christianity (Philip II of France, Richard I of England and Frederick I, Holy Roman Emperor); and it became to be called, the "Kings Crusade" l with the goal of reconquering the Holy Land following the capture of Jerusalem by the Ayyubid sultan Saladin in 1187.
The Crusade did not achieve its primary goal to recapture Jerusalem from Saladin, but it successfully regained vital coastal territory, including Jaffa and Acre and it established a stable, Crusader presence that lasted for another century
