Publius Valerius Poplicola or Publicola was one of four Roman aristocrats who led the overthrow of the monarchy and became a Roman consul, the colleague of Lucius Junius Brutus in 509 BC, traditionally considered the first year of the Roman Republic.

Lucius Junius Brutus is the semi-legendary founder of the Roman Republic, and traditionally one of its first consuls in 509 BC.

The Battle of Lake Regillus was a legendary Roman victory over the Latin League shortly after the establishment of the Roman Republic and as part of a wider Latin War.

The Battle of Silva Arsia was a battle in 509 BC between the republican forces of ancient Rome and the Etruscan forces of Tarquinii and Veii led by the deposed Roman king Lucius Tarquinius Superbus. The battle took place near the Silva Arsia (the Arsian forest) in Roman territory and resulted in victory to Rome but the death of one of her consuls, Lucius Junius Brutus.

Tensions came to a head when the king's son, Sextus Tarquinius, raped Lucretia, wife, and daughter to a powerful Roman noble. Lucretia told her relatives about the attack and committed suicide to avoid the dishonor of the episode. Four men, led by Lucius Junius Brutus, and including Lucius Tarquinius Collatinus, Publius Valerius Poplicola, and Spurius Lucretius Tricipitinus incited a revolution that deposed and expelled Tarquinius and his family from Rome in 509 BC. Tarquin was viewed so negatively that the word for king, rex, held a negative connotation in the Latin language until the fall of the Roman Empire.
