Marcomannic Wars
The Marcomannic Wars (Latin: bellum Germanicum et Sarmaticum, lit. 'German and Sarmatian war') were a series of wars lasting from about AD 166 until 180. 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.
