Louis the German, also known as Louis II of Germany, was the first king of East Francia, and ruled from 843 to 876 AD. Grandson of emperor Charlemagne and the third son of Louis the Pious, emperor of Francia, and his first wife, Ermengarde of Hesbaye, he received the appellation Germanicus shortly after his death, when East Francia became known as the kingdom of Germany.
