Rome began by the annihilation of the Etruscans. When Rome began it started as a Republic between 500 B.C. and 1500 A.D the system was unchanged except for some minor changes. The Roman republic was first set up in 500 B.C.
The Roman republic was originally set ip to have two consuls that were in charge of the army and making laws. The consuls were given advice from the Senate which was made up of only rich men. The consuls could veto anything that the Senate said but the two consuls had to both agree on something before it could be passed. In the end the consuls usually listened to what the Senate said. After the two men were consuls they usually end up being part of the senate.
Later in the Republic around 146 B.C. the republic started to fall apart. The Romans realized that they could no longer rely on the senate to run the empire. The Romans looked forward to their next general to see what he could accomplish.
Instead of just one man, three men formed what is called a triumvirate. These three men were Pompey, Crassus, and Julius Caeser. Pompey and Crassus fade and Caeser had an affair with Cleopatra. This then leads up to his murder.
After this the second triumvirate came into play. This consisted of Octavian, Caeser's nephew, Ledipus, and Mark Antony. Ledipus was eventually forced out of power and Octavian and Antony got into a civil war. Octavian won and Mark Antony commited suicide. (Hadas 44)(Barnett 14-15)
