The Third Crusade, occurring from 1189 to 1192, was a military campaign initiated in response to the capture of Jerusalem by Saladin in 1187. It involved a coalition of European leaders, including Richard the Lionheart of England, Philip II of France, and Frederick I Barbarossa of the Holy Roman Empire, who aimed to reclaim the Holy City and restore Christian control over the region. The Crusade marked a pivotal moment in medieval history, showcasing both the power struggles within Europe and the enduring significance of Jerusalem in Christian and Islamic contexts.
