Establishment
January 407: In the last months of 406, the lack of attention paid by the government of Honorius to Britain, increasingly threatened by the incursions of barbarian invaders and pirates, prompted the British legions to revolt acclaiming the general Flavius Claudius Constantine as emperor. These managed to temporarily block the advance of the barbarians and to take control of a large part of the Empire: Gaul, Spain and Britain.

At the end of 406 AD a large group of Alans, Suebi and Vandals invaded the Roman Empire.
January 408: A barbarian horde of extraordinary proportions, made up of Vandals, Alans and Suebi, driven westward by the Huns, crossed the frozen Rhine and penetrated into Gaul.
The Alans, Suebi and Vandals occupied and partitioned the Iberian Peninsula.
November 409: In the last months of 409 Vandals, Alans and Suebi, entered Spain, subjecting it for the most part. According to the testimony of the Spanish chronicler Hydatius, the Vandals, the Alans and the Swabians divided up the territories conquered in Spain by drawing lots.
Maximus was a Roman usurper in Hispania.

The inhabitants of Britannia and Armorica expelled the Romans.

In 411, the Burgundians settled on the left (Roman) bank of the Rhine, between the river Lauter and the Nahe, seizing Worms, Speyer, and Strassburg.
