What did Antony and Octavius argue about?

Answer 1

Octavian (later he was called Augustus) and mark Antony fought a civil war over who would rule the Roman Empire alone (The final Civil War of the Roman Republic, 32-30 BC). Octavian won and became the first Roman emperor under the name of Augustus.

Augustus's original name was Gaius Octavius. It changed to Gaius Julius Caesar Octavianus (Octavian) when he was adopted by Julius Caesar in his will in 44 BC. He renamed himself Gaius Julius Caesar Divis Filus (Gaius Son of the Divine Julius Caesar) in 42 BC when Julius Caesar was deified and Imperator Caesar Divi Filius in 38 BC. In 27 BC, when he became the first Roman Emperor, he was given the religious honorary tile of Augustus. His name became Imperator Caesar Divi Filius Augustus. His traditional name in common parlance became Augustus.

Historians use Octavian to refer to the period from 44 BC to 27 BC and Augustus to refer to the period from 27 BC to 14 BC (the year of his death).
