In the second half of the second century BC, as the Seleucid Empire disintegrated during wars with Parthia (145–129 BC), Edessa became the capital of the Abgarid dynasty, who founded the kingdom of Osroene (also known as Edessa). This kingdom was established by Arabs from the northern Arabian Peninsula and lasted nearly four centuries (c. 132 BC to A.D. 214), under twenty-eight rulers, who sometimes called themselves "king" on their coinage. Edessa was at first more or less under the protectorate of the Parthians, then of Tigranes of Armenia, Edessa was Armenian Mesopotamia's capital city, then from the time of Pompey under the Roman Empire. Following its capture and sack by Trajan, the Romans even occupied Edessa from 116 to 118, although its sympathies towards the Parthians led to Lucius Verus pillaging the city later in the 2nd century.
