Charles the Fat
On 6 December 884, King Carloman II of West Francia died without a male heir and his half-brother, the future Charles the Simple, was just a five-year-old boy. Because of this, their cousin Charles the Fat, already Holy Roman Emperor and King of East Francia, was invited by the nobles of the Kingdom to assume the throne. Since the beginning, the new monarch was forced to deal with constant Viking raids, with little success. After three years of incompetent government, Charles the Fat was finally deposed by the Diet of Tribur in 887.
