Bohemond I of Antioch and Richard of the Principate, who invaded the territory and briefly occupied the city in 1100, according to Matthew of Edessa. Their rule was short-lived. They were captured by the Turks in an ambush in August 1100. History Creation In 1104, the Byzantine general Manuel Boutoumites occupied Marash during his campaign against the Principality of Antioch. He placed the general Monastros in charge of the city. When the latter was recalled, Thathoul returned to power and handed the city over to Joscelin of Courteny, lord of Turbessel in the County of Edessa. It appears that Thathoul, unable to defend the city, preferred to see it pass to Edessa rather than Antioch. Late in 1104, Joscelin was captured by the Turks at the battle of Harran. He remained their prisoner until 1108. From the writings of Ibn al-Furat, it appears that one of Joscelin's vassals was give control of Marash during his lord's imprisonment. Tancred called on Marash for assistance when Ridwan of Aleppo invaded his country in 1105. The unnamed vassal is described as the lord of Marash and Joscelin's standard-bearer during the fighting between Joscelin and Prince Tancred of Antioch in 1108. By that year, however, Marash had passed to Richard of the Principate. The Chronicle of 1234 describes Richard as returning to "his own country, Marash", after his regency of Edessa came to an end in 1108, implying that he had already acquired Marash by then. Vassal of Antioch Richard held Marash as a vassal of Antioch. It is not clear how he acquired actual control, but he may have been appointed lord of Marash as early as 1100, when Bohemond briefly controlled it. There is no documentary evidence of Richard's title as lord of Marash, but Albert of Aachen calls him a prefect (praefectus). The territorial extent of the lordship is also unknown. After 1104, it seems to have functioned as the Antiochene counterpoise to the Edessene lordship of Turbessel. Richard supplied 60 knights and 100 infantry against the Turkish invasion of Antioch in September 1111. Around the same time the lordship was established, Bohemond set up a Latin diocese of Marash subject to the Latin patriarch of Antioch. Richard was probably dead by 1112, when his son Roger became regent of Antioch. Walter the Chancellor records that the lord of Marash died during an earthquake in 1114, but does not name him.
