County of Edessa
1099 CE – 1151 CE · Capital: Edessa (1098–1144; 1146), (modern-day Şanlıurfa, Turkey), Turbessel (1144–1146; 1146–1150), (modern-day Gündoğan, Oğuzeli, Gaziantep, Turkey) · 40,929 km²

The County of Edessa (Latin: Comitatus Edessanus) was a 12th-century Crusader state in Upper Mesopotamia. Its seat was the city of Edessa (modern Şanlıurfa, Turkey). In the late Byzantine period, Edessa became the centre of intellectual life within the Syriac Orthodox Church. As such it also became the centre for the translation of Ancient Greek philosophy into Syriac, which provided a stepping stone for the subsequent translations into Arabic. When the crusades arrived, it was still important enough to tempt a side-expedition after the siege of Antioch.

Origins and Founding
In 1098, Baldwin of Boulogne left the main Crusading army, which was travelling south towards Antioch and Jerusalem. He went first south into Cilicia, then east to Edessa, where he convinced its lord, Thoros, to adopt him as son and heir. He also married Thoros' daughter, Arda of Armenia, who eventually became the first queen of Jerusalem. Thoros was a Christian of Armenian origin but of Greek Orthodox religion and largely disliked by his Armenian Apostolic subjects, which led to his removal from power in March 1098. Different sources claim he was assassinated or abdicated, and it is debated whether Baldwin played a role in this. Nonetheless, Baldwin succeeded Thoros as ruler, taking the title of count (having been Count of Verdun as a vassal of his brother in Europe).

In 1100, Baldwin became King of Jerusalem when his brother, Godfrey of Bouillon, died.

Government, Society and Religion
Turbessel was firstly the lordship of Joscelin I when he was not yet the count of Edessa. It controlled the area west of the Euphrates, and held the border against Antioch. It then was a special holding of Courtenay counts of Edessa, and again became their seat after the loss of the city of Edessa. It was sold with the remaining parts of the county to the Byzantines just before it was conquered by Muslims. After the sale, the wife and family of Joscelin II moved with the proceeds to the Kingdom of Jerusalem, near Acre.

Wars and Battles
Baldwin II quickly became involved in the affairs of northern Assyria and Asia Minor. He helped secure the ransom of Bohemond I of Antioch from the Danishmends in 1103, and, with Antioch, attacked the Byzantine Empire in Cilicia in 1104.

Later in 1104, Edessa was attacked by Mosul, and both Baldwin and Joscelin were taken prisoner after their defeat at the Battle of Harran. Bohemond's cousin Tancred became regent in Edessa (although Richard of Salerno actually governed the territory), until Baldwin and Joscelin were ransomed in 1108. Baldwin had to fight to regain control of the city; Tancred was eventually defeated, though Baldwin had to ally with some of the local Muslim rulers.
Baldwin II became King of Jerusalem (also as Baldwin II) when Baldwin I died in 1118. Although Eustace of Boulogne had a better claim as the late Baldwin's brother, he was in France and did not want the title.

Decline and Fall
Joscelin was gravely injured during a siege in 1131 and was succeeded by his son Joscelin II. By this time, Zengi had united Aleppo and Mosul and began to threaten Edessa.

Meanwhile, Joscelin II paid little attention to the security of his county, and argued with the counts of Tripoli who then refused to come to his aid. Zengi besieged the city in 1144, capturing it on 24 December that year. Joscelin continued to rule his lands west of the Euphrates, and he also managed to take advantage of the death of Zengi in September 1146 to regain and briefly hold his old capital. The city was again lost in November, and Joscelin barely escaped. In 1150 he was captured by Zengi's son Nur ad-Din, and was kept a prisoner in Aleppo until he died in 1159.
