Which crusade is known as the only successful crusade that conquered Jerusalem?

The First Crusade is renowned for being the only successful campaign that culminated in the conquest of Jerusalem. Launched in 1096 with the goal of recapturing the Holy Land from Muslim control, it involved a mix of motivations, including religious fervor, the promise of spiritual rewards, and the opportunity for land and wealth. The crusaders, after a long and arduous journey, captured Jerusalem in 1099, marking a significant achievement within the context of the series of crusades.

The First Crusade is notable not only for its military success but also for the establishment of several Crusader states in the Levant, including the Kingdom of Jerusalem. This success, however, would not last indefinitely, as later crusades were less effective in maintaining control over the region and often ended in failure or diminished impact. Understanding the significance of the First Crusade provides insights into the broader context of Crusades and their long-term implications for Christian-Muslim relations.
