Son of Louis I the Pious and Princess Irmengard (or Hildegard), and grandson of Charlemagne. Louis I the Pious, son of Charlemagne, divided the Carolingian empire (817) between his and three heir sons, namely, Lothar I as co-emperor with his father and received the The imperial title of Italy, Pepino was made king of Aquitaine, and Louis the Germanicus was given the Eastern Frankish Kingdom, Bavaria (or Bavaria), in Germany's home territory. current.
With a new marriage, with Judite, he had another son (823), Carlos o Calvo. The father then tried to place him as successor, but the three brothers would not accept. After years of conflict within the family, Pepino died (838) and his father Louis I (840), and the three surviving brothers began a civil war to divide the Empire. Allied with Carlos, they took (841) Bavaria from their brother Lothario who had the support of Pepino II, Pepino's replacement, who had been defeated in Fontenay, France. Allied formally, together they quelled a Saxon revolt (842) and a revolt in Aquitaine.
After the oath of Strasbourg (842), he signed the Treaty of Verdun (843) with the other two brothers by which Charles would take over the Western Frankish Kingdom, present-day France, and with Aquitaine, Lothair would rule the Middle Frankish Kingdom, comprising Italy, Provence and Lorraine, and he would reign in the Eastern Frankish Kingdom, now Germany and hence nicknamed the Germanic. He continued, in his reign, the Christian and Germanic expansion to the southeast, reaching Bohemia, Moravia and the banks of the Danube.
He fought the Northern Slavs and the Danes, with operations entrusted to Count Liudolf, predecessor of the future House of Saxony. Sensing Charles' weakness to the nobles, he invaded the Western Frankish Kingdom (858) and called a synod of bishops, hoping for the support of the clergy. But Hincmar, Archbishop of Reims, remained loyal to Charles and rallied the Church against the invader. Expelled from France (860), he made peace with Lothar II of Lotharingia, his nephew, who wished to divorce his wife without his children and marrying Waldrada, an action that Pope Nicholas I was against and had the support of Carlos.
Lotario won the fight and remarried (862). Lothario the brother died (863), and the kingdom was divided between the two surviving brothers and peace reigned between them until his death at Frankfurt amr Main. Then the kingdom of the East was divided between his three sons, Louis the Younger, Carlomano and Charles the Fat.
