Maroboduus withdrew to Bohemia and sent for assistance to Tiberius. He was refused on the grounds that he had not moved to help Varus. Drusus encouraged the Germans to finish him off. A force of Goths under Catualda, a Marcomannian exile, bought off the nobles and seized the palace. Maroboduus escaped to Noricum and the Romans offered him refuge in Ravenna where he remained the rest of his life. He died in 37 AD. After his expulsion the leadership of the Marcomanni was contested by their Suebic neighbours and allies, the Hermunduri and Quadi. Marcomannic wars In the 2nd century AD, the Marcomanni entered into a confederation with other peoples including the Quadi, Vandals, and Sarmatians, against the Roman Empire. The war began in 166, when the Marcomanni overwhelmed the defences between Vindobona and Carnuntum, penetrated along the border between the provinces of Pannonia and Noricum, laid waste to Flavia Solva, and could be stopped only shortly before reaching Aquileia on the Adriatic sea. The war lasted until Marcus Aurelius' death in 180. In the third century Jordanes claims that the Marcomanni paid tribute to the Goths, and that the princes of the Quadi were enslaved. The Vandals, who had moved south towards Pannonia, were apparently still sometimes able to defend themselves. Migration period In 259/60, one or more groups of Suebi appear to have been the main element in the formation of a new tribal alliance known as the Alemanni who came to occupy the Roman frontier region known as the Agri Decumates, east of the Rhine and south of the Main. The Alamanni were sometimes simply referred to as Suebi by contemporaries, and the region came to be known as Swabia - a name which survives to this day. People in this region of Germany are still called Schwaben, a name derived from the Suebi. One specific group in the region in the 3rd century, sometimes distinguished from the Alamanni, were the Juthungi, which a monument found in Augsburg refers to as Semnones. These Suebi for the most part stayed on the east bank of the Rhine until 31 December 406, when much of the tribe joined the Vandals and Alans in breaching the Roman frontier by crossing the Rhine, perhaps at Mainz, thus launching an invasion of northern Gaul. It is thought that this group probably contained a significant amount of Quadi, moving out of their homeland
