What happendduring the first second and third crusades?

The First Crusade (1096-1099) was launched in response to Pope Urban II's call to reclaim Jerusalem from Muslim control, resulting in the capture of the city in 1099. The Second Crusade (1147-1149) was initiated after the fall of the County of Edessa, but it ended in failure as the crusaders were unable to secure significant victories. The Third Crusade (1189-1192), prompted by the recapture of Jerusalem by Saladin, saw notable leaders like Richard the Lionheart and Philip II of France, but ultimately failed to retake the city, leading to a treaty that allowed Christians to visit Jerusalem.
