In early 44 BC, Julius Caesar announced his intentions to invade Parthia and restore Roman power in the East. His reasons were to punish the Parthians for assisting Pompey in the recent civil war, to avenge Crassus' defeat at Carrhae, and especially to match the glory of Alexander the Great for himself. Before Caesar could launch his campaign, however, he was assassinated. As part of the compromise between Antony and the Republicans to restore order following Caesar's murder, Publius Cornelius Dolabella was assigned the governorship of Syria and command over Caesar's planned Parthian campaign. The compromise did not hold, however, and the Republicans were forced to flee to the East. The Republicans directed Quintus Labienus to attract the Parthians to their side in the resulting war against Antony and Octavian. After the Republicans were defeated at the Battle of Philippi, Labienus joined the Parthians. Despite Rome's internal turmoil during the time, the Parthians did not immediately benefit from the power vacuum in the East due to Orodes II's reluctance despite Labienus' urgings to the contrary.
