Joscelin II was the fourth and last ruling count of Edessa. He was son of his predecessor, Joscelin I, and Beatrice, daughter of Constantine I of Armenia.

Baldwin II, also known as Baldwin of Bourcq or Bourg, was Count of Edessa from 1100 to 1118, and King of Jerusalem from 1118 until his death. He accompanied his cousins Godfrey of Bouillon and Baldwin of Boulogne to the Holy Land during the First Crusade. He succeeded Baldwin of Boulogne as the second count of Edessa when he left the county for Jerusalem following his brother's death. He was captured at the Battle of Harran in 1104. He was held first by Sökmen of Mardin, then by Jikirmish of Mosul, and finally by Jawali Saqawa. During his captivity, Tancred, the Crusader ruler of the Principality of Antioch, and Tancred's cousin, Richard of Salerno, governed Edessa as Baldwin's regents.
