"Charles III (13 June 839 – 13 January 888), also known as Charles the Fat, was the emperor of the Carolingian Empire[a] from 881 to 888. ...
A member of the Carolingian dynasty, Charles was the youngest son of Louis the German and Hemma, and a great-grandson of Charlemagne. He was the last Carolingian emperor of legitimate birth and the last to rule over all the realms of the Franks.
Over his lifetime, Charles became ruler of the various kingdoms of Charlemagne´s former empire. Granted lordship over Alamannia in 876, following the division of East Francia, he succeeded to the Italian throne upon the abdication of his older brother Carloman of Bavaria who had been incapacitated by a stroke. Crowned Emperor in 881 by Pope John VIII, his succession to the territories of his brother Louis the Younger (Saxony and Bavaria) the following year reunited the kingdom of East Francia. Upon the death of his cousin Carloman II in 884, he inherited all of West Francia, thus reuniting the entire Carolingian Empire." - (en.wikipedia.org 31.01.2020)
