Mark Antony's Parthian campaign in the east was disrupted by the events of the Perusine War (41–40 BC), initiated by his ambitious wife Fulvia against Octavian in the hopes of making her husband the undisputed leader of Rome. It has been suggested that Fulvia wanted to cleave Antony away from Cleopatra, but the conflict emerged in Italy even before Cleopatra's meeting with Antony at Tarsos. Fulvia and Antony's brother Lucius Antonius were eventually besieged by Octavian at Perusia (modern Perugia, Italy) and then exiled from Italy, after which Fulvia died at Sicyon in Greece while attempting to reach Antony. Her sudden death led to a reconciliation of Octavian and Antony at Brundisium in Italy in September 40 BC. Although the agreement struck at Brundisium solidified Antony's control of the Roman Republic's territories east of the Ionian Sea, it also stipulated that he concede Italia, Hispania, and Gaul, and marry Octavian's sister Octavia the Younger, a potential rival for Cleopatra.
