Remarks:
The future emperor was born T. Aurelius Fulvus Boionius Arrius Antoninus on September 19, A.D. 86 at Lanuvium, an old Latin city southeast of Rome. His father's family had originally migrated to Rome from Nemausus (Nîmes) in Narbonese Gaul, but his paternal grandfather, T. Aurelius Fulvus, had served twice as Roman consul and also as city prefect and his father, Aurelius Fulvus, also held the consulship. The future emperor's mother was Arria Fadilla and her father, Arrius Antoninus, had also been consul twice. Young Antoninus was raised at Lorium, on the via Aurelia, where he later built a palace.
Antoninus Pius is regarded as one of the "Five Good Emperors" in Roman history. He was born in 86 AD. Around 133-136, he served in Asia as proconsul, and there he earned the respect of Emperor Hadrian. After Hadrian's return from the Jewish war, Antoninus was made a member of his council not only on grounds of friendships and family connection, but because of his experience as a jurist and administrator. After the sudden death of L. Aelius Verus Caesar, Antoninus was officially adopted by Hadrian on February 25, 138 as successor to the throne. After administering the imperial offices, Hadrian died and Antoninus became emperor.
Antoninus married Faustina and they had four children: two sons and two daughters. However, only one daughter was alive at the time of his adoption by Hadrian. Later, he adopted Marcus Aurelius, who was to be the successor to his throne. In 139, he gave to Marcus the name of Caesar and made him consul designate. In 146, Aurelius was recognized as Antoninus's colleague in rule, and the hopes of Rome and the fortunes of the dynasty rested upon him.
