Lord of a powerful Franco-Armenian principality centered on the town of Marash (mod. Kahramanmaras, Turkey) in eastern Cilicia from around 1136. Baldwin was probably a brother or half-brother of Raymond of Poitiers, prince of Antioch. In 1146 he died in the unsuccessful attempt of Count Joscelin II of Edessa to recapture the city of Edessa from Nûr al-Dīn. His life was commemorated in a funeral oration by his Armenian chaplain Basil, who emphasized his fluency in the Armenian language and attachment to Armenian customs.
