Marcus Vipsanius Agrippa (63 BC – 12 BC) was a Roman general and statesman who was a close friend, son-in-law and lieutenant to the Roman emperor Augustus. Agrippa is well known for his important military victories, notably the Battle of Actium in 31 BC against the forces of Marcus Antonius and Cleopatra. He was also responsible for the construction of some of the most notable buildings of his era, including the original Pantheon.
Born to a plebeian family c. 63 BC, in an uncertain location in Roman Italy, he met the future emperor Augustus, then known as Octavianus, at Apollonia, in Illyria. Following the assassination of Octavianus' great-uncle Julius Caesar in 44 BC, Octavianus returned to Italy. Around this time, Agrippa was elected tribune of the plebs. He served as a military commander, fighting alongside Octavianus and Caesar's former general and right-hand man Marcus Antonius in the Battle of Philippi. In 40 BC, he was praetor urbanus and played a major role in the Perusine war against Lucius Antonius and Fulvia, respectively the brother and wife of Marcus Antonius. In 39 or 38 BC, Agrippa was appointed governor of Transalpine Gaul.
