Respuesta :
Rome becomes a republic. It became a republic in 509 BC, Julius Ceasar is assassinated in 44 BC, and Rome becomes an empire when Augustus takes power in 27 BC.
The correct answer is "Rome becoming a republic". Rome becoming a republic is traditionally dated to 509 BC, after the Roman kingdom was overthrown. This was the first event in the options, because Caesar Augustus taking power occurred in 27 BC, Julius Caesar’s assassination is dated on 44 BC and, Rome becoming an empire is marked by the crowning of Gaius Octavian Thurinus in 31 B.C.
