Who is considered to be the first Roman emperor?

Question

What did Emperor Charles V, the Holy Roman Emperor, aim to achieve when he called the Diet of Worms together in 1521?

Answer 1

Augustus
Julius Caesar was Dictator, and Consul, of the Roman Republic but at the time of his death the Republic was still a republic and not an empire. Augustus built the empire, and his powers, following the assassination of Julius Caesar by Brutus and others for what were thought to be his intention to assume autocratic imperial powers. Tiberius succeeded Augustus as emperor.
