The Second Crusade (1147–1149) was largely unsuccessful. It was launched in response to the capture of Edessa by the Seljuk Turks in 1144, but failed to retake the city.
The Third Crusade (1189–1192) was led by the Holy Roman Emperor Frederick Barbarossa, the French King Philip II Augustus, and the English King Richard I. It succeeded in recapturing Jerusalem from the Ayyubid Sultan Saladin, but failed to establish a lasting Christian presence in the city.
