Louis I was known for: Holding the Carolingian Empire together in the wake of his father Charlemagne's death. Louis was the only designated heir to survive his father.

In 813 he became co-emperor with his father, then, when Charlemagne died a year later, he inherited the empire -- though not the title Roman Emperor. The empire was a conglomerate of several different ethnic groups, including Franks, Saxons, Lombards, Jews, Byzantines and many others across a great span of territory. Charlemagne had handled the many differences and the large size of his realm by dividing it up into "sub-kingdoms," but Louis represented himself not as a ruler of different ethnic groups, but as a leader of Christians in a unified land. As emperor, Louis initiated reforms and redefined the relationship between the Frankish empire and the papacy. He carefully structured a system whereby various territories could be assigned to his three grown sons while the empire remained intact. He took swift action in quashing challenges to his authority and even sent his half-brothers into monasteries to prevent any future dynastic conflicts. Louis also performed voluntary penance for his sins, a display that deeply impressed contemporary chroniclers. The birth of a fourth son in 823 to Louis and his second wife, Judith, triggered a dynastic crisis. Louis's elder sons, Pippin, Lothair and Louis the German, had maintained a delicate if uneasy balance, and when Louis attempted to reorganize the empire to include little Charles, resentment raised its ugly head. There was a palace revolt in 830, and in 833 when Louis agreed to meet Lothair to settle their differences (at what became known as the "Field of Lies," in Alsace), he was instead confronted by all his sons and a coalition of their supporters, who forced him to abdicate. But within a year Louis had been released from confinement and was back in power. He continued to rule energetically and decisively until his death in 840.
