County of Edessa
Joscelin of Courtenay (or Joscelin I) (died 1131), Prince of Galilee and Lord of Turbessel (1115–1131) and Count of Edessa (1119–1131), ruled over the County of Edessa during its zenith, from 1118 to 1131. Captured twice, Joscelin continued to expand his county, even participating in the Battle of Azaz in 1125. Gravely injured during the collapse of a sapper mine, Joscelin would march his army to relieve the besieged fortress of Kaysun, and died soon after.
