Why did Pope Urban the second want to capture Jerusalem and the Holy Land?

Pope Urban II aimed to capture Jerusalem and the Holy Land primarily to reclaim Christian territories that had fallen under Muslim control, which he viewed as a vital aspect of Christendom. He also sought to unite European Christians through the call for the First Crusade, promoting a sense of religious duty and solidarity against a common enemy. Additionally, the capture of Jerusalem would enhance the Church's authority and influence, reinforcing the papacy's leadership in religious matters.
