Marcus Tullius Cicero (3 January 106 BC - 7 December 43 BC), was a Roman philosopher, politician, lawyer, orator, political theorist, consul and constitutionalist, widely considered one of Rome's greatest orators and prose stylists. Though he was an accomplished orator and successful lawyer, Cicero believed his political career was his most important achievement. During the chaotic latter half of the 1st century BC marked by civil wars and the dictatorship of Gaius Julius Caesar, Cicero championed a return to the traditional republican government. Following Julius Caesar's death Cicero became an enemy of Mark Antony in the ensuing power struggle, attacking him in a series of speeches. He was proscribed as an enemy of the state by the Second Triumvirate and consequently executed by soldiers operating on their behalf in 43 BC.
