8Antoninus Pius (19 September, 86 AD – 7 March, 161 AD)

He was one of the most peaceful rulers in the history of the Roman Empire. There are no records of any significant military action during his reign.

He built temples, theaters, and mausoleums, promoted the Roman arts and science, and bestowed honors and financial rewards upon the teachers of rhetoric and philosophy. Antoninus was virtually unique among Roman emperors because he dealt with these crises without leaving Italy once. This style of government was highly praised by his contemporaries and later generations.
