AD 14 (XIV) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Pompeius and Appuleius. The denomination AD 14 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Marcus Agrippa Postumus, later named Agrippa Julius Caesar, was a grandson of Roman Emperor Augustus. He was the youngest child of Marcus Vipsanius Agrippa and Julia the Elder. Augustus initially considered Postumus as a potential successor and formally adopted him as his heir, before banishing Postumus from Rome in AD 6 on account of his ferocia. In effect, though not in law, the action cancelled his adoption and virtually assured Tiberius' emplacement as Augustus' sole heir. Postumus was ultimately executed by his own guards shortly after Augustus' death in AD 14.
Marcus Vipsanius Agrippa was a Roman general, statesman and architect 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.
