Louis II the Stammerer

Louis the Stammerer (846–879), eldest son of Charles the Bald, was nicknamed for his stammer. In 866 he succeeded his brother as king of Aquitaine, and in 877 his father's death brought him the West Frankish throne, crowned at Compiègne.

Pope John VIII crowned him again at Troyes in 878 and may have offered him the imperial crown, which he declined. He died at Compiègne in 879 marching against Viking raiders, leaving the realm to his sons Louis III and Carloman II.
