 The Roman world was redivided, with Antony receiving the Eastern provinces, Octavian the Western provinces, and Lepidus relegated to a clearly junior position as governor of Africa.This agreement, known as the "Treaty of Brundisium", reinforced the Triumvirate and allowed Antony to begin preparing for Caesar's long-awaited campaign against the Parthian Empire.As a symbol of their renewed alliance, Antony married Octavia, Octavian's sister, in October 40 BC.
