Did Cicero oppose Marc Antony?

Cicero's opposition to Marc Antony is well-documented and forms a significant part of Roman political history following the assassination of Julius Caesar. After Caesar's death, Cicero became a vocal critic of Antony, viewing him as a potential tyrant threatening the Republic's stability. His opposition intensified as Antony's maneuvers began to consolidate power, and Cicero took a leading role in the efforts to restore the Senate's authority.

In his speeches, particularly the series known as the Philippics, Cicero eloquently denounced Antony, labeling him as a demagogue and a threat to liberty. This period of Cicero’s political life illustrates his commitment to the ideals of the Republic, which he believed Antony was undermining. Therefore, the answer confirms Cicero's staunch opposition to Antony throughout this tumultuous time, highlighting his dedication to political discourse and the preservation of the Republic.
