Antoninus Pius 

Titus Aurelius Fulvius Boinonius Arrius  Antoninus 138 - 161

Adopted by Hadrian early in his reign. Antoninus ascended the throne on the death of his adoptive father. As a result of his heartfelt and successful pleading for Hadrian to be deified, he was granted the title "Pius" by the senate. The reign of Antoninus Pius probably represents the very pinnacle of the Roman Imperial period. Few wars were fought, and the borders of the empire remained pretty static. One notable exception was the extension of the Empire in Britain north of Hadrian's Wall to the shorter border between the Solway and the Forth, now called the Antonine Wall. This was short-lived, however. The peacefulness of his reign, and his even-handed, beneficial rule assured him of a place amongst the gods on his death.
