Lucius Cassius Longinus
At the time of Caesar's murder in 44 B.C., Carfulenus was tribune of the plebs. He was a supporter of the aristocratic party, and an opponent of Marcus Antonius, the general of Caesar. When Antonius summoned the senate to the Capitol on November 28, in order to have Caesar's nephew, Octavianus, declared an enemy of the state, Carfulenus and his colleagues, Tiberius Canutius and Lucius Cassius Longinus, were excluded from the Capitol, so that they could not interpose their veto against the senate's decree.
