In a meeting near Bologna in October 43 BC, Octavian, Antony, and Lepidus formed the Second Triumvirate. This explicit arrogation of special powers lasting five years was then legalised by law passed by the plebs, unlike the unofficial First Triumvirate formed by Pompey, Julius Caesar, and Marcus Licinius Crassus. The triumvirs then set in motion proscriptions, in which between 130 and 300 senators and 2,000 "equites" were branded as outlaws and deprived of their property and, for those who failed to escape, their lives. This decree issued by the triumvirate was motivated in part by a need to raise money to pay the salaries of their troops for the upcoming conflict against Caesar's assassins, Marcus Junius Brutus and Gaius Cassius Longinus. Rewards for their arrest gave incentive for Romans to capture those proscribed, while the assets and properties of those arrested were seized by the triumvirs.
