Pompey's eastern settlement

Pompey's Eastern Settlement was the reorganization of Asia Minor and the Levant carried out by the Roman general Pompey in the 60s BC, in the aftermath of his suppression of piracy, his victory in the Third Mithridatic War and the dissolution of the Seleucid Empire, which brought the entire Near East under Roman control. It involved the establishment of new Roman provinces: alongside an enlarged Asia, Bithynia and Pontus in the north and Cilicia in the south, while the Seleucid realm was annexed as the province of Syria. In the interior, a network of native client kingdoms was established as a buffer to the Parthian Empire. Pompey also carried out reforms to the provincial administrative and taxation systems in the Roman East, and founded new cities. Although generally acknowledged as humane and sound, the Eastern Settlement was carried out without the advice or consent of the Roman Senate, and the reorganization was not ratified for several years due to senatorial opposition against Pompey, who stood to gain enormous prestige, as well as expand his patronage over the entire East. This eventually led Pompey to join forces with Crassus and Julius Caesar in the First Triumvirate; ratification of the eastern settlement was one of the main legislative planks of Caesar's first consulship in 59 BC. Many of the provisions of Pompey's survived for centuries, well into the Roman Empire.
