On June 20, 840, Louis I the Pious, Holy Roman Emperor, died at the age of 62. An excerpt from the article:
"In 781 Louis was appointed king of Aquitaine, one of the "sub-kingdoms" of the Carolingian Empire, and though he was only three years old at the time he would acquire great experience managing the kingdom as he matured. 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."
