Commodus was a Roman emperor who ruled from 177 until his assassination in 192. For the first three years of his reign he was co-emperor with his father Marcus Aurelius. Commodus' sole rule, starting with the death of Aurelius in 180, is commonly thought to mark the end of a golden age of peace and prosperity in the history of the Roman Empire.

The Marcomannic Wars were a series of wars lasting from about 166 until 180 AD. These wars pitted the Roman Empire against principally the Germanic Marcomanni and Quadi and the Sarmatian Iazyges; there were related conflicts with several other Germanic, Sarmatian and Gothic peoples along both sides of the whole length of the Roman Empire's northeastern European border, the river Danube.
