Which crusade was a sucess to free the holy land?

The First Crusade (1096-1099) was the most successful in terms of freeing the Holy Land. Crusaders captured Jerusalem in 1099 after a lengthy siege, establishing several Crusader states in the region. This victory was driven by a combination of religious fervor, military strategy, and the disarray among Muslim forces at the time. However, the success was not sustained long-term, leading to further conflicts in the region.
