Explanation:
Rome's military was ever tightly keyed to its federal policy. In the Roman kingdom, the political status of a person affected both his state and military purposes. The political rule was from an early date based upon opposition within the ruling aristocracy. Senators in the Republic fought desperately for state office, the most coveted of which was the post of Consul. Two were selected each year to head the state of the state and would be allowed a consular army and an area in which to fight. From Gaius Marius and Sulla onwards, the power of the army started to be balanced into the political aspirations of individuals, beginning with the executive triumvirate of the 1st century BC and its army decision.
