What happened when crusaders entered Jerusalem during the first crusade?

When the Crusaders entered Jerusalem during the First Crusade in July 1099, they encountered fierce resistance but ultimately captured the city after a month-long siege. The Crusaders committed widespread atrocities, including the massacre of many of the city's Muslim and Jewish inhabitants, as they sought to reclaim the holy site. The fall of Jerusalem marked a significant victory for the Crusaders, leading to the establishment of the Kingdom of Jerusalem. This event intensified the religious fervor of the Crusades and solidified the city's status as a focal point of Christian pilgrimage.
