Charles the Fat

Last Carolingian to briefly reunite the entire empire of Charlemagne under one ruler, between 884 and 887. His reign collapsed under the combined pressure of his epileptic illness, his ineffectual response to Viking sieges of Paris, and the open contempt of his nobles. Deposed by an assembly at Tribur in November 887, he died in obscurity three months later. His fall ended the political unity of the Frankish world.
