Roman Republic Silver Denarius of M. Baebius Tampilus (about 2160 years ago)

The Roman Republic (Latin: Res publica Romana [ˈreːs ˈpuːblɪka roːˈmaːna]) was the era of classical Roman civilisation 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 following the War of Actium. During this period, Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world.

Roman society at the time was primarily a cultural mix of Latin and Etruscan societies, as well as of Sabine, Oscan, and Greek cultural elements, which is especially visible in the Ancient Roman religion and its pantheon. Its political organisation developed at around the same time as direct democracy in Ancient Greece, with collective and annual magistracies, overseen by a senate.^[4] There were annual elections, but the republican system was an elective oligarchy, not a democracy; a small number of powerful families largely monopolised the magistracies. Roman institutions underwent considerable changes throughout the Republic to adapt to the difficulties it faced, such as the creation of promagistracies to rule its conquered provinces, and differences in the composition of the senate.
