Markoman wars [166-180]

The Marcomannic Wars were a series of wars lasting over a dozen years 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 barbarian peoples along both sides of the whole length of the Roman Empire's northeastern European border, the river Danube. The struggle against the Germans and Sarmatians occupied the major part of the reign of Roman emperor Marcus Aurelius
