The Crusades
European Christians fought to control the Holy Land.
About this topic
The Crusades were a series of religious wars between 1095 and 1291 in which European Christians, urged by the pope, tried to capture Jerusalem and the Holy Land from Muslim rule. Pope Urban II called the First Crusade at the Council of Clermont in 1095 after the Byzantine emperor asked for help against the Seljuk Turks. Crusaders were promised spiritual rewards and often hoped for land and wealth.
The First Crusade captured Jerusalem in 1099 and set up crusader states, but a massacre of civilians followed. Muslim leader Saladin retook Jerusalem in 1187, leading to the Third Crusade, in which Richard the Lionheart negotiated a truce with him. The Fourth Crusade sacked Christian Constantinople in 1204, damaging relations between east and west. Later crusades failed, and Acre fell in 1291.
Effects were far reaching: trade with the East grew, especially for Italian cities such as Venice and Genoa, and Europeans encountered new goods, ideas and learning, while mistrust between Christians and Muslims deepened. Monarchs gained power as many nobles died or sold land. Example: knightly orders like the Templars guarded pilgrims and later became rich bankers. A misconception is that the Crusades were purely about religion; politics and economics mattered too.
