Part of Pompey the Great's campaigns in the East
The siege of Jerusalem (63 BC) occurred during Pompey the Great's campaigns in the East, shortly after his successful conclusion of the Third Mithridatic War. Pompey had been asked to intervene in a dispute over inheritance to the throne of the Hasmonean Kingdom, which turned into a war between Hyrcanus II and Aristobulus II. His conquest of Jerusalem spelled the end of an independent Jewish state, and thus the incorporation of Judea as a client kingdom of the Roman Republic and later as a province of the Roman Empire.
