A Consul was a official appointed by the Roman government to reside in another country
Some Consuls led the army and the government, while others also acted as judges and high priests
When the Consuls left for war they sometimes appointed a dictator to serve in their place, Consuls appointed dictators for periods of six months.
In 458 B.C. the Consuls appointed a farmer soldier named Cincinnatus to serve as a dictator, according to legend he raised an army, defeated the enemy, and handed power back to the Consuls in just 16 days
I believe expansion was the most interesting idea about the Roman Empire.I think it was important because it determined how far the empire stretched.Also since the slaves took most of the Roman jobs the expansion gave more land for new jobs and new jobs meant less homeless people.Even though expansion caused wars and death I think it was the most interesting idea about Rome.
