Crusades
General
The Crusades were a series of military, political, and religious campaigns between Latin Christian powers and Muslim states in the eastern Mediterranean.
Although the term includes multiple fronts, this note focuses on the major expeditions connected to the Holy Land from the call in 1095 to the fall of Acre in 1291.

End of the Crusader States
The capture of Acre in 1291 marked the effective end of mainland Crusader rule in the Levant.
After this point, Latin Christian power in the region depended mainly on maritime networks and Cyprus rather than territorial states in Palestine.
Historical Significance
- Long-term transformation of Mediterranean diplomacy and warfare.
- Intensified cultural contact and conflict between Latin Christian and Muslim polities.
- Strengthening of royal and papal institutions in Europe, but also repeated crises of legitimacy after failed expeditions.
