Modern Countries Once Part of Roman Republic

At its mapped extent, Roman Republic covered territory in 26 present-day countries. The period shown is when the mapped borders include that country, and the note says how much of it.

Derived by testing mapped cities against this polity's dated territorial polygons, so the list is indicative and follows the borders in the source dataset.

Roman Republic in Depth

History

Rome had been ruled by monarchs since its foundation. These monarchs were elected, for life, by the men of the Roman Senate. The last Roman monarch was called Tarquin the Proud, who in traditional histories was expelled from Rome in 509 BC because his son, Sextus Tarquinius, raped a noblewoman, Lucretia. The tradition asserted that the monarchy was abolished in a revolution led by the semi-mythical Lucius Junius Brutus and the king's powers were then transferred to two separate consuls elected to office for a term of one year; each was capable of checking his colleague by veto.

Military

Rome's military secured Rome's territory and borders and helped to impose tribute on conquered peoples. Rome's armies had a formidable reputation; but Rome also "produced [its] share of incompetents" and catastrophic defeats. Nevertheless, it was generally the fate of Rome's greatest enemies, such as Pyrrhus and Hannibal, to win early battles but lose the war.

During this period, Roman soldiers seem to have been modelled after those of the Etruscans to the north, who themselves are believed to have copied their style of warfare from the Greeks. Traditionally, the introduction of the phalanx formation into the Roman army is ascribed to the city's penultimate king, Servius Tullius (ruled 578–534).

People and economy

The Roman Republic's economy was predominantly agrarian, but also highly complex. As the Romans continued to conquer the Mediterranean basin, it became fully integrated with the wider Mediterranean economy, a process which completed during the first century BC. The population of the republic expanded considerably during the centuries of its existence; indeed, the vastness of the Roman citizen population was part of how it was able to mobilise such expansive military power.

Agricultural production during the republic was highly regional. Literary evidence from ancient elite writers was highly simplifying and is not entirely consistent with the regional differences revealed by modern archaeology.

Culture

The basic Roman garment was the Greek-style tunic, worn knee-length and short-sleeved (or sleeveless) for men and boys, and ankle-length and long-sleeved for women and girls. The toga was distinctively Roman and became a mark of male citizenship, a statement of social degree. Convention also dictated the type, colour and style of calcei (ankle-boots) appropriate to each level of male citizenship.

The whitest, most voluminous togas were worn by the senatorial class. High-ranking magistrates, priests, and citizen's children were entitled to a purple-bordered toga praetexta.

Imperial History & Territorial Expansion

Forged from the Roman Republic following the civil wars of Julius Caesar and Octavian Augustus, the Roman Empire unified the Mediterranean basin into "Mare Nostrum" (Our Sea). Its administrative genius lay in monumental civil infrastructure—over 80,000 kilometers of paved roads, monumental aqueducts, and legal codes codified in the Corpus Juris Civilis that remain foundational to modern Western jurisprudence.
