Lucius Verus in the context of "Marcus Cornelius Fronto"

Marcus Aurelius Antoninus (/ɔːˈriːliəs/ or-EE-lee-əs, Latin: [ˈmaːrkʊs au̯ˈreːli.us antoːˈniːnʊs]; 26 April 121 – 17 March 180) was Roman emperor from 161 to 180 and a Stoic philosopher. He was a member of the Nerva–Antonine dynasty, the last of the rulers later known as the Five Good Emperors and the last emperor of the Pax Romana, an age of relative peace, calm, and stability for the Roman Empire lasting from 27 BC to 180 AD. He served as Roman consul in 140, 145, and 161.

Marcus Aurelius was the son of the praetor Marcus Annius Verus and his wife, Domitia Calvilla. He was related through marriage to the emperors Trajan and Hadrian. Marcus was three when his father died, and was raised by his mother and paternal grandfather. After Hadrian's adoptive son, Aelius Caesar, died in 138, Hadrian adopted Marcus's uncle Antoninus Pius as his new heir. In turn, Antoninus adopted Marcus and Lucius, the son of Aelius. Hadrian died that year, and Antoninus became emperor. Now heir to the throne, Marcus studied Greek and Latin under tutors such as Herodes Atticus and Marcus Cornelius Fronto. He married Antoninus's daughter Faustina in 145.

The Nerva–Antonine dynasty comprised seven Roman emperors who ruled from AD 96 to 192: Nerva (96–98), Trajan (98–117), Hadrian (117–138), Antoninus Pius (138–161), Marcus Aurelius (161–180), Lucius Verus (161–169), and Commodus (177–192). The first five of these are popularly known as the "Five Good Emperors".

The first five of the six successions within this dynasty were notable in that the reigning emperor did not have a male heir, and had to adopt the candidate of his choice to be his successor. Under Roman law, an adoption established a bond legally as strong as that of kinship.

Lucius Aelius Caesar (13 January 101 – 1 January 138) was the father of Emperor Lucius Verus. In 136, he was adopted by the reigning emperor Hadrian and named heir to the throne. He died before Hadrian and thus never became emperor. After Lucius' death, he was replaced by Antoninus Pius, who succeeded Hadrian the same year.

Herodes Atticus (Ancient Greek: Ἡρώδης; AD 101–177) was an Athenian rhetorician, as well as a Roman senator. A great philanthropic magnate, he and his wife Appia Annia Regilla, for whose murder he was potentially responsible, commissioned many Athenian public works, several of which stand to the present day. He was one of the best-known figures of the Antonine Period, and taught rhetoric to the Roman emperors Marcus Aurelius and Lucius Verus, and was advanced to the consulship in 143. His full name as a Roman citizen was Lucius Vibullius Hipparchus Tiberius Claudius Atticus Herodes.

According to Philostratus, Herodes Atticus, in possession of the best education that money could buy, was a notable proponent of the Second Sophistic. Having gone through the cursus honorum of civil posts, he demonstrated a talent for civil engineering, especially the design and construction of water-supply systems. The Nymphaeum at Olympia was one of his dearest projects. However, he never lost sight of philosophy and rhetoric, becoming a teacher himself. One of his students was the young Marcus Aurelius, last of the "Five Good Emperors". M.I. Finley describes Herodes Atticus as "patron of the arts and letters (and himself a writer and scholar of importance), public benefactor on an imperial scale, not only in Athens but elsewhere in Greece and Asia Minor, holder of many important posts, friend and kinsman of emperors."

Annia Galeria Faustina the Elder, sometimes referred to as Faustina I or Faustina Major (c. 100 – late October 140), was a Roman empress and wife of the Roman emperor Antoninus Pius. The emperor Marcus Aurelius was her nephew and later became her adopted son, along with Emperor Lucius Verus. She died early in the principate of Antoninus Pius, but continued to be prominently commemorated as a diva, posthumously playing a prominent symbolic role during his reign.

The Column of Antoninus Pius (Italian: Colonna di Antonino Pio) is a Roman honorific column in Rome, Italy, devoted in AD 161 to the Roman emperor Antoninus Pius, in the Campus Martius, on the edge of the hill now known as Monte Citorio, and set up by his successors, the co-emperors Marcus Aurelius and Lucius Verus. The column itself is now destroyed, but its base is preserved.
