II. Marcus Vipsanins, a Roman general and statesman, born in 68 B. C, of an obscure family, died in March, 12 B. C. He was a schoolmate of Octavius (afterward Octavianus and Augustus), at Apol-lonia in Illyria, and was his chief instrument in establishing the empire. After the murder of Julius Caesar, Agrippa accompanied Octavius to Rome, prosecuted Cassius, and received the oath of fidelity from the legions which had declared for Octavius. In 40 he took Perusia from Lucius Antonius after a long siege, and Sipontum from Mark Antony. In 38 he aided Octavianus by his victories in Gaul. In 37, after converting the Lucrine lake into a harbor, he created a fleet, with which the next year he decisively defeated Sextus Pompey at Mylae and Naulochus. In the subsequent war against Antony he also commanded the fleet, and chiefly contributed to the great victory at Ac-tium in 31. He accompanied Augustus to the war against the Cantabrians in Spain in 25; and in 19, being in command there, he entirely subdued them, after having in the same year pacified the Gauls, and constructed four great roads and the aqueduct at Nimes. Agrippa was praetor in 41, consul (with Octavianus) in 37, 28, and 27, Aedile in 33, and tribune from 18 till his death.

During his Aedileship he made great public improvements at his own expense, constructing and restoring aqueducts, erecting splendid buildings, etc.; and in his third consulship he built the Pantheon. In 16, after a journey to Jerusalem on the invitation of Herod the Great, he founded Berytus (Bey-rout). He died suddenly on his return from a successful mission to tranquillize Pannonia. Agrippa was married first to Pomponia, daughter of T. Pomponius Atticus; afterward (about 28) to Marcella, niece of Augustus; and in 21 to Julia, Augustus's daughter, Marcella having been divorced at the emperor's desire. His sons Caius and Lucius by Julia were adopted by Augustus, but they both died young. His posthumous son Agrippa was also adopted by Augustus, but was afterward banished for life to the island of Planasia on account of his savage disposition, and on the accession of Tiberius, A. D. 14, was put to death.
