Marcus Aemilius Lepidus (executed 39)
Marcus Aemilius Lepidus, (6–39) was the son of consul Lucius Aemilius Paullus.
He and his sister Aemilia Lepida were both married to siblings of the Emperor Caligula (Aemilia married Caligula's elder brother Drusus Caesar; Lepidus married to Caligula's younger sister Julia Drusilla).
He was also great-grandson of Lucius Aemilius Lepidus Paullus (consul of 50 BC and brother of the triumvir Marcus Aemilius Lepidus).
Some areas of his lineage are unclear.
However, through his mother Julia the Younger, Lepidus was the great grandson of Emperor Augustus Caesar.
Lepidus married Caligula's sister Drusilla sometime in November or December of 37.
Little is known about him prior to this.
Drusilla had been married to Lucius Cassius Longinus since 33 but Caligula forced his brother-in-law to divorce Drusilla so that she could marry Lepidus.
The marriage lasted until Drusilla's death in June 38.
They had no children.
Because of this marriage, Lepidus had become a close friend to Caligula and his family.
After the death of Gemellus in 37, Lepidus was publicly marked by Caligula as his heir.
In late 38, when the governor of Egypt Aulus Avilius Flaccus was arrested, Lepidus successfully persuaded Caligula to exile Flaccus to Andros rather than Gyarus.
Sometime in 39, however, Caligula made public letters by his sisters Agrippina the Younger and Julia Livilla that detailed an adulterous affair with Lepidus and a plot against the emperor.
Lepidus was executed and Caligula's sisters were exiled.
Agrippina was given the bones of Lepidus in an urn, and she carried them to Rome.
Caligula sent three daggers to the Temple of Mars the Avenger to celebrate the death.
In the Senate, Vespasian made a motion that the remains of Lepidus be thrown away instead of buried.
The motion was carried and Lepidus was not given a proper burial.
Marcus Aemilius Lepidus (78 BC)
Marcus Aemilius Lepidus( 120 BC – 77 BC) was a Roman statesman and general.
After the death of Lucius Cornelius Sulla, he attempted to undermine the Sullan constitution and revive the" populares" faction.
This brought him into conflict with the optimates whom Sulla had put back in power.
In 77 BC, when he was recalled from his proconsulship of Gaul, he returned to Rome at the head of an army and an armed conflict erupted.
Lepidus' forces were defeated in a battle near the Milvian Bridge and as a result his rebellion failed.
He was the father of the triumvir Marcus Aemilius Lepidus and of one of the consuls for 50 BC Lucius Aemilius Lepidus Paullus.
Lucius Aemilius Lepidus Paullus (consul 34 BC)
Lucius Aemilius Lepidus Paullus also known as Paullus Aemilius Lepidus( c. 77 BC – after 11 BC) was a Roman Senator.
Paullus was a member of the gens Aemilia.
He was a grandson of Marcus Aemilius Lepidus and Appuleia through their son Lucius Aemilius Lepidus Paullus by his unnamed wife.
His paternal uncle Marcus Aemilius Lepidus served as a member of the Second Triumvirate.
Paullus served as consul in 34 BC and censor in 22.
Paullus first married Cornelia( c. 54 BC- 16 BC).
With Cornelia, Paullus had three children: Lucius Aemilius Paullus( c. 37 BC- 14 AD) the husband of Julia the Younger and consul in AD 1; Marcus Aemilius Lepidus( c. 30 BC- 33 AD), consul in AD 6; and a daughter Aemilia Paulla( c. 22 BC).
Aemilia was married twice: first to Lucius Munatius Plancus, consul in AD 13; second to Publius Memmius Regulus.
Paullus was widowed in 18 BC, the same year Cornelia's brother Publius Cornelius Lentulus Marcellinus was consul.
Not long after Cornelia's death, he married Claudia Marcella Minor, one of the daughters of consul Gaius Claudius Marcellus Minor and Octavia the Younger, as her maternal uncle was the Roman emperor Augustus.
The marriage of Marcella and Paullus linked two honored republican houses and tied them closely to the imperial circle.
At some point after 11 BC, Marcella bore him a son, Paullus Aemilius Regulus, who later served as a quaestor during the rule of the Roman emperor Tiberius.
Marcus Aemilius Lepidus (consul 232 BC)
Marcus Aemilius Lepidus( died 216 BC) was the Roman consul for 232 BC, and according to Livy served again as" suffect" consul, possibly in 221.
He also served at one time as augur.
He died in 216.
It was in Lepidus' honor that the first gladiatorial games(" munera") were held, on the occasion of his death.
He was survived by his three sons; Lucius, Quintus, and Marcus.
The latter was most likely the Marcus Aemilius Lepidus who was a Roman consul and Pontifex Maximus in the early 2nd century BC.
