Cicero supported Decimus Junius Brutus Albinus as governor of Cisalpine Gaul ("Gallia Cisalpina") and urged the Senate to name Antony an enemy of the state. The speech of Lucius Piso, Caesar's father-in-law, delayed proceedings against Antony. Antony was later declared an enemy of the state when he refused to lift the siege of Mutina, which was in the hands of Decimus Brutus. Cicero's plan to drive out Antony failed. Antony and Octavian reconciled and allied with Lepidus to form the Second Triumvirate after the successive battles of Forum Gallorum and Mutina. The Triumvirate began proscribing their enemies and potential rivals immediately after legislating the alliance into official existence for a term of five years with consular "imperium". Cicero and all of his contacts and supporters were numbered among the enemies of the state, even though Octavian argued for two days against Cicero being added to the list.
