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.

The Marcomanni were first reported by Julius Caesar among the Germanic peoples who were attempting to settle in Gaul in 58 BC under the leadership of Ariovistus, but he did not explain where their homeland was. After a major defeat to the Romans in about 9 BC, the Marcomanni somehow received a new king named Maroboduus, who had grown up in Rome. He subsequently led his people and several others into a region surrounded by forests and mountains in what is now the Czech Republic. Before 9 BC the homeland of the Marcomanni is not known, but archaeological evidence suggests that they lived near the central Elbe river and Saale, or possibly to the southwest of this region in Franconia.
