In 63 BCE the Roman general Pompey sacked Jerusalem and made the Jewish kingdom a client of Rome. The situation was not to last, as the deaths of Pompey in 48 BCE and Caesar in 44 BCE, together with the related Roman civil wars, relaxed Rome's grip on Judea. This resulted in the Parthian Empire and their Jewish ally Antigonus the Hasmonean defeating the pro-Roman Jewish forces (high priest Hyrcanus II, Phasael and Herod the Great) in 40 BCE. They invaded the Roman eastern provinces and managed to expel the Romans. Antigonus was made King of Judea. Herod fled to Rome, where he was elected "King of the Jews" by the Roman Senate and was given the task of retaking Judea. In 37 BCE, with Roman support, Herod reclaimed Judea, and the short-lived reemergence of the Hasmonean dynasty came to an end. From 37 BCE to 6 CE, the Herodian dynasty, Jewish-Roman client kings, ruled Judea. In 20 BCE, Herod began a refurbishment and expansion of the Second Temple in Jerusalem. His son, Herod Antipas, founded the Jewish city of Tiberias in the Galilee.
