Lepidus was the son of Cornelia and Lucius Aemilius Lepidus Paullus and brother-in-law to Augustus' granddaughter Julia the Younger, who was married to his brother Lucius Aemilius Paullus, consul in 1 AD. Thus, he was a member of one of the oldest patrician families, the Aemilii. He became consul in 6 AD. He then distinguished himself as legate in charge of an army during the Illyrian War under the command of Tiberius, the later emperor. After the end of the war he served as governor either of Dalmatia or Pannonia. At the time of Augustus' death, in 14 AD, he was governor of Northern Spain in charge of an army of three legions. While there were serious riots in the armies in Germany and Pannonia after Augustus' death, Lepidus' army gave no trouble.
Activities during the reign of Tiberius
Lepidus defended Gnaeus Calpurnius Piso at his trial for the alleged poisoning of Germanicus. In 21 AD, Tiberius offered him the governorship of Africa Province. He rejected the offer, claiming ill-health and the demands of his children, but more likely he recognised the wisdom of leaving the position to Quintus Junius Blaesus, uncle of Lucius Aelius Sejanus, the powerful praetorian prefect. Although this may make Lepidus seem unduly subservient towards the emperor Tiberius and his powerful allies, Lepidus' activities in the senate show an independent mind. In 21 AD he made a strong speech against the death penalty for an irreverent poet. Nevertheless, the poet was executed by order of the senate. This allowed Tiberius to praise Lepidus' moderation. Modern scholars have suggested that Lepidus also restored the Basilica Aemilia in the Roman Forum in 22 AD and served as governor of Asia in 26 AD. Apparently, Lepidus was one of the few aristocrats obtaining high positions in this troubled time without ever being accused of plotting against the emperor. Although in 32 AD an important senator, Cotta Messalinus, openly attacked him because of his excessive influence in the senate, this accusation had no consequences. Lepidus died in 33 AD. Tacitus described him as "wise and noble" for his actions as a senator. According to Tacitus his actions could be taken as an example for independent aristocrats living under tyranny.
