Marcus Vipsanius Agrippa (/əˈɡrɪpə/; c. 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 Mark Antony 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 Octavian, at Apollonia, in Illyria. Following the assassination of Octavian's great-uncle Julius Caesar in 44 BC, Octavian returned to Italy. Around this time, Agrippa was elected tribune of the plebs. He served as a military commander, fighting alongside Octavian and Caesar's former general and right-hand man Mark Antony 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 Mark Antony. In 39 or 38 BC, Agrippa was appointed governor of Transalpine Gaul. In 38 BC, he put down a rising of the Aquitanians and fought the Germanic tribes. He was made consul for 37 BC, despite being well below the usual minimum age of 43, in order to oversee the preparations for war against Sextus Pompey, who had cut off grain shipments to Rome.
