A philippic (/fɪˈlɪpɪk/) is a fiery, damning speech, or tirade, delivered to condemn a particular political actor. The term is most famously associated with two noted orators of the ancient world, Demosthenes of Athens and the Roman Cicero, although it can be applied to any speech of this type.
The original "philippics" were delivered by Demosthenes, Greek statesman and orator of ancient Athens who delivered several attacks on Philip II of Macedon in the 4th century BC.
A First, Second, and Third Philippic have been ascribed to Demosthenes. A Fourth Philippic is also extant, but is of disputed authorship.
Cicero consciously modeled his own condemnations of Mark Antony on Demosthenes's speeches, and if the correspondence between Marcus Junius Brutus the Younger and Cicero is genuine [ad Brut. ii 3.4, ii 4.2], at least the fifth and seventh speeches were referred to as the Philippics in Cicero's time. They were also called the Antonian Orations by Latin author and grammarian Aulus Gellius.
After the death of Caesar, Cicero privately expressed his regret that the murderers of Caesar had not included Antony in their plot, and he bent his efforts to the discrediting of Antony. Cicero even promoted illegal action, such as legitimatizing the private army of Gaius Octavius, or Octavian. In all, Cicero delivered fourteen Phillipics in less than two years. Cicero's focus on Antony, however, contributed to his downfall as he failed to recognize the threat of Octavian to his republican ideal.
