The Crusades

The Crusades (1095-1291) were a series of religious wars in which Christian Europeans attempted to capture and hold the Holy Land.

Why the Crusades Happened

Religious motivation: Jerusalem — where Christ died and rose — was sacred to Christians. Its control by Muslims (since 638) troubled Western Christendom.

  • Remission of sins for crusaders
  • Eternal salvation for those who died
  • Younger sons sought land and glory
  • Merchants saw commercial opportunities
  • Adventure and escape from home

The First Crusade (1095-1099)

Remarkably successful. An army of perhaps 100,000 (soldiers, families, camp followers) marched across Europe and the Middle East.

1099: Jerusalem captured. The crusaders massacred the Muslim and Jewish populations.

Four Crusader States established: Jerusalem, Antioch, Tripoli, Edessa.

Later Crusades

Second Crusade (1147-1149): Failed to recapture Edessa.

Third Crusade (1189-1192): Saladin retook Jerusalem (1187). Richard the Lionheart couldn't recapture it but secured pilgrimage access.

Fourth Crusade (1202-1204): Infamously sacked Constantinople — a Christian city.

Children's Crusade (1212): Thousands of young people set out; most died or were enslaved.

Subsequent crusades achieved little. The last Crusader stronghold (Acre) fell in 1291.

Legacy

  • Increased trade with the East
  • Transfer of knowledge (medicine, mathematics)
  • Gothic architecture influenced by Islamic designs
  • Massacres and destruction
  • Deepened Christian-Muslim hostility
  • Precedent for religious violence

The Crusades remain controversial, viewed very differently in the West and the Islamic world.
