Marcus Tullius Cicero (106 - 43 BCE) was a Roman statesman, lawyer, orator, scholar, and writer. He served as consul in the year 63 BC. It was during his consulship that the second Catiline conspiracy attempted to overthrow the government through an attack on the city by outside forces, and Cicero suppressed the revolt by summarily executing five conspirators. During the chaotic latter half of the first century BCE, marked by civil wars and the dictatorship of Julius Caesar, Cicero championed a return to the traditional republican government. Following Caesar's death, Cicero became an enemy of Mark Antony in the ensuing power struggle. He was proscribed as an enemy of the state by the Second Triumvirate and subsequently executed.
Along with Lucretius, Cicero helped introduce philosophic writing to Rome and forged a new Latin philosophical vocabulary. His mastery of language firmly established him as a model of Latin prose for later ages. Petrarch's rediscovery of Cicero's letters is often credited for initiating the fourteenth-century Renaissance in public affairs, humanism, and classical Roman culture.
