The Crusades
The Crusades were a series of religious military campaigns launched by European Christians, primarily aimed at capturing the Holy Land from Muslim control, spanning roughly two centuries beginning in 1095.
The First Crusade was called by Pope Urban II in 1095, urging European Christians to reclaim Jerusalem and other holy sites, resulting in the establishment of several short-lived Crusader states in the Middle East.
Over the following two centuries, a series of further Crusades were launched with varying degrees of success, marked by significant violence, including massacres of both Muslim and Jewish populations, as well as periods of trade and cultural exchange between East and West.
The Crusader presence in the Holy Land ultimately ended with the fall of Acre in 1291, though the Crusades' legacy continues to influence relations and historical memory between the Christian and Islamic worlds today.
