Final answer:
Octavius and Mark Antony argued over power and control within the Roman Empire, leading to a series of confrontations that ended with Octavius defeating Antony at the Battle of Actium, after which Antony and his ally Cleopatra committed sui_cide.
Step-by-step explanation:
About what do Octavius and Antony argue? Octavius, later known as Augustus, and Mark Antony were once allies who divided the Roman Empire among themselves along with Lepidus. However, their alliance eventually broke down leading to conflict. The tension escalated when Antony formed an alliance with Cleopatra, the queen of Egypt. This partnership, combined with military and romantic elements, turned into a power struggle between Antony and Octavius.
After a series of political and military confrontations, their feud culminated in the Battle of Actium in 31 BCE, where Octavian's forces defeated Antony and Cleopatra's navy. Following their defeat, Antony and Cleopatra fled to Egypt and eventually committed sui_cide, which left Octavian as the sole ruler and he effectively transformed the Roman Republic into the Roman Empire, assuming the title Augustus.
