十字军东征（1096年－1291年）是一系列在罗马天主教教宗的准许下进行的有名的宗教性军事行动，由西欧的封建领主和骑士对地中海东岸的国家以收复阿拉伯入侵占领的土地名义发动的战争。当时原属于罗马天主教圣地的耶路撒冷落入伊斯兰教手中，罗马天主教为了收复失地，便进行多次东征行动。

The Crusades were a series of intermittent military campaigns sanctioned by various Popes in the Middle Ages, from 1096 to 1487. In 1095, Byzantine Emperor Alexios I sent an ambassador from Constantinople to Pope Urban II in Italy requesting military support in the conflict with the eastward invading Turks. The Pope responded promptly by calling Catholic soldiers to join the First Crusade. The immediate goal was to guarantee pilgrims access to the holy sites in the Holy Land that were under Muslim control. His long-range goal was to reunite the Eastern and Western branches of Christendom after their split in 1054, with the pope as head of the united Church. A complex 200-year struggle ensued.
