Territory of the Roman Empire. Roman Empire. Roman Republic. The Roman Republic (Latin: Res Pvblica Romana) was the period of the ancient Roman civilization when the government operated as a republic.
It began with the overthrow of the Roman monarchy, traditionally dated around 509 BC, and its replacement by a government headed by two consuls, elected annually by the citizens and advised by a senate. A complex constitution gradually developed, centered on the principles of a separation of powers and checks and balances. Except in times of dire national emergency, public offices were limited to one year, so that, in theory at least, no single individual wielded absolute power over his fellow citizens.
During the first two centuries of its existence the Republic expanded through a combination of conquest and alliance, from central Italy to the entire Italian peninsula. By the following century it included North Africa, the Iberian Peninsula, Greece, and what is now southern France. Capitolium.
