What are the main goal of the first crusade?

The main goal of the First Crusade, launched in 1096, was to reclaim Jerusalem and the Holy Land from Muslim control, responding to a call for help from Byzantine Emperor AlexiOS I. It aimed to secure safe pilgrimage routes for Christians and to expand Christendom. Additionally, it sought to unite warring factions within Christianity and redirect the aggressive energies of European knights towards a common religious cause. Ultimately, the campaign concluded with the capture of Jerusalem in 1099, establishing several Crusader states in the region.
