30s BC
Octavian defeats Mark Antony and Cleopatra VII of Egypt at the Battle of Actium (2 September 31 BC). On August 30 BC Octavian captures Alexandria. Marcus Antonius and Cleopatra suicide (kill themselves). Romans kill Cleopatra's son and co-ruler (this means they ruled the country together) Ptolemy XV Caesarion. Egypt becomes part of the Roman Republic and Octavian becomes the ruler of Rome and all Romans. Rome will soon become an Empire not a Republic.
