Who did Cicero have debates against?

Cicero had notable debates against prominent figures such as Mark Antony and Catiline. His speeches during the Catilinarian Conspiracy targeted Catiline, who plotted to overthrow the Roman Republic. In his later years, Cicero engaged in political and rhetorical battles against Antony, particularly in his series of speeches known as the "Philippics," which criticized Antony's ambitions and actions. These debates were pivotal in shaping Roman politics during the late Republic.
