County of Edessa

The County of Edessa was a 12th-century Crusader state in Upper Mesopotamia, founded in 1098 CE and dissolved around 1150 CE. Its capital was the city of Edessa, which had been a significant center of intellectual life for the Syriac Orthodox Church and a hub for translating Ancient Greek philosophy. Unlike other Crusader states, the County of Edessa was landlocked and remote, making it particularly vulnerable. Its fall in 1144, the first major setback for Outremer, prompted the Second Crusade, though Edessa was never recovered by the Christians.
