Answer
"Superbus," as a cognomen for Lucius Tarquinius, meant "proud," "arrogant," or "lofty" in Latin. This aptly described his haughty demeanor and tyrannical rule as the seventh and final king of Rome. His oppressive reign, marked by excessive pride and disregard for the rights of the Roman people, ultimately led to his downfall and the establishment of the Roman Republic in 509 BCE."
