First Crusade (1095 CE):
- Triggered by the Seljuk Turk's capture of Jerusalem and parts of Anatolia, as well as their persecution of Christian pilgrims traveling to the Holy Land.
- Pope Urban II's call for a holy war or Crusade aimed to reclaim these lost Christian territories and secure safe passage for pilgrims.
Third Crusade (1189-1192 CE):
- Prompted by Saladin's (Salahuddin's) recapture of Jerusalem in 1187 CE.
- This military leader had unified much of the Islamic world and posed a significant threat to the remaining Crusader states.
- European rulers, including Frederick Barbarossa, Philip II of France, and Richard I of England, felt compelled to respond given the loss of Christian control over significant parts of the Holy Land.
Overall, both Crusades were reactions to Muslim territorial gains that aimed to recover important areas of religious and spiritual significance for Christians.
