Marcus (371-October 406) was a Romano-British usurper of the Western Roman Empire from July to October 406, preceding Gratian.
Biography[]
Flaccus Marcus was born in Roman Britain in 371 to a Romano-British Christian family. He served as a Dux Britanniarum under the Western Roman Empire, and, in the summer of 406, the Roman Army proclaimed him emperor, as they were alienated from Rome due to its withdrawal of Roman units from Britain despite increasing Saxon pirate raids. The rebellion was aimed primarily at Stilicho, who had withdrawn several Roman legions from England, but his brief reign failed to please the army, which murdered him in October 406 and replaced him with Gratian.
