Established four crusader states in the holy land

The four crusader states established in the Holy Land during the Crusades were:

1. The Kingdom of Jerusalem: Established in 1099 after the capture of Jerusalem during the First Crusade. It encompassed much of modern-day Israel and Palestine and remained the most significant crusader state throughout the period.

2. The County of Tripoli: Established in 1109 after the capture of the city of Tripoli during the First Crusade. It covered parts of modern-day Lebanon and northern coastal Syria.

3. The Principality of Antioch: Established in 1098 after the successful siege of Antioch during the First Crusade. It encompassed the region around the city of Antioch, which is now located in modern-day Turkey.

4. The County of Edessa: Established in 1098 after the capture of Edessa during the First Crusade. It covered parts of modern-day Turkey and northern Syria. However, it was the first crusader state to fall to the Muslims in 1144.
