One of the main factors that helped Rome change from a republic to an empire was the proclamation of Augustus as an emperor following a civil war. Augustus, who succeeded Julius Caesar, went to war with Queen Cleopatra from Egypt. The Battle of Actium, as it came to be known, was Rome’s last war to crush the Egyptian Empire. Though Augustus lost his life, he was declared a hero and promoted to the Status of Emperor. Rome then became an Empire.
