Gaius Maecenas
After Caesar's assassination, his friend and chief lieutenant, Marcus Antonius, seized the last will of Caesar and using it in an inflammatory speech against the murderers, incited the mob against them. The murderers panicked and fled to Greece. In Caesar's will, his grandnephew Octavianus, who also was the adopted son of Caesar, was named as his political heir. Octavian returned from Apollonia (where he and his friends Marcus Vipsanius Agrippa and Gaius Maecenas had been studying and helping in the gathering of the Macedonian legions for the planned invasion of Parthia) and raised a small army from among Caesar's veterans. After some initial disagreements, Antony, Octavian, and Antony's ally Marcus Aemilius Lepidus, formed the Second Triumvirate. Their combined strength gave the triumvirs absolute power. In 42 BC, they followed the assassins into Greece, and mostly because of the generalship of Antony, defeated them at the Battle of Philippi on 23 October. To pay for about forty legions that were engaged by the triumvirate for this purpose, proscriptions were declared against about 300 senators and 2000 equites, including Cicero, who was killed at his villa. After the victory, about 22 of the largest Italian cities suffered confiscations to provide land for the veterans.
