The Marcomanni were a Germanic people who lived close to the border of the Roman Empire, north of the River Danube, and are mentioned in Roman records from approximately 60 BC until about 400 AD. They were one of the most important members of the powerful cluster of allied Suebian peoples in this region, which also included the Hermunduri, Varisti, and Quadi along the Danube, and the Semnones and Langobardi to their north.
