|138-161 AD. Aureus, 7.30g. Rome, 140-4 CE||Antoninus Pius, also known as Antoninus, was Roman emperor from 138 to 161. He was one of the Five Good Emperors. He is remembered by history as a kind, just, and wise emperor. Antoninus Pius was an “Adopted Emperor”, where succession was a conscious decision, not a birthright. |
After the death of Hadrian’s first adopted son, Lucius Aelius, on February 25, 138 CE, Antoninus was formally adopted by Hadrian. It was agreed that he would be made emperor with the provision that he would, in turn, adopt Marcus Aurelius.
