Roman Empire (high empire, mid second century)
Pius
86 – 161 CE
The emperor of whom almost nothing dramatic is recorded — and that absence is the point. His long, peaceful, well-administered reign is the high empire functioning exactly as designed, and the standing test of whether an uneventful government is the same thing as a good one.
