The Marcomannic Wars (Latin: bellum Germanicum et Sarmaticum, "German and Sarmatian War") were a series of wars lasting over a dozen years from about AD 166 until 180. These wars pitted the Roman Empire against, principally, the Germanic Marcomanni and Quadi and the Sarmatian Iazyges as well as 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.
