Карл III Толстый
The later years of Louis the German were troubled by rebellions of his sons. The eldest, Carloman of Bavaria, revolted in 861 and again two years later. This was followed by the second son Louis the Younger, who was joined by his brother Charles the Fat. In 864 Louis was forced to grant Carloman the kingdom of Bavaria, which he himself had once held under his father. In 865 he divided the remainder of his lands—Saxony with Franconia and Thuringia went to Louis the Younger and Swabia with Raetia to Charles the Fat.
