The Roman Republic (Latin: Res publica Romana; Classical Latin: (ˈreːs ˈpuːb. lɪ. ka roːˈmaː.na)) was the era of ancient Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome 's control expanded from the city 's immediate surroundings to hegemony over the entire Mediterranean world.
