Marcus Tullius Cicero is a Roman statesman, orator, and philosopher widely regarded as one of the greatest voices in classical antiquity and a foundational figure in Western rhetoric and political thought. Born in Arpinum, in the Roman Republic, he rose to prominence as a lawyer and orator before becoming consul in 63 BCE, the highest office in the Roman Republic, where he famously exposed and suppressed the Catiline conspiracy. He is remembered for works including On Duties, On the Republic, and his extensive collections of speeches and letters, texts that continue to be studied as foundational works of philosophy, rhetoric, and Roman political history. A staunch defender of the Roman Republic, he ultimately paid for his political opposition to Mark Antony with his life, killed in 43 BCE amid the power struggles following Julius Caesar's assassination. Known for his eloquence and unflinching commitment to civic duty, justice, and republican governance, Cicero's work continues to shape modern political philosophy and rhetoric and inspire readers across the world.
