Louis III of West Francia

Louis III (863/865–882), eldest son of Louis the Stammerer, became king of West Francia in 879, his legitimacy disputed. In 880 he and his brother Carloman II divided the kingdom at Amiens, Louis taking Neustria, and by the Treaty of Ribemont ceded western Lotharingia to East Francia.

He failed to take Vienne from Boso of Provence, but in August 881 he and Carloman crushed Viking raiders at Saucourt-en-Vimeu, a victory praised in the Ludwigslied. In August 882 he died at Saint-Denis after striking his head on a low lintel while chasing a girl on horseback.
