Louis the Pious

The only surviving son of Charlemagne who ruled the Franks and faced civil war among his sons.

His reign was marked by civil wars with his sons over succession plans.^[1] In 814, upon the death of his father Charlemagne, Louis the Pious became the ruler of the Carolingian Empire, inheriting all its territories except the kingdom of Italy.^[2] When set beside his father, Louis is typically viewed less favorably, yet the challenges he encountered were of a quite different nature.^[1]

Life and work

Louis was born in 778 at the Carolingian villa of Cassinogilum, the third son of Charlemagne and Hildegard.^[3] Charlemagne constituted this sub-kingdom to secure the border after the war against the Aquitanians and Basques.^[4] His first act was to purge the palace of what he considered undesirable.^[5] In 817, after a gallery collapse killed many, Louis issued the Ordinatio Imperii for dynastic succession.^[4]

At the age of three, in 781, Louis was made King of Aquitaine through a coronation.^[6] In 791, when he was fourteen years old, Louis underwent a formal ceremony where he was given his armour.^[7] When his father died in 814, Louis took over the entire Carolingian Empire, though Italy was not included in this inheritance.^[2] The pagan tokens and texts from old Germanic traditions that Charlemagne had gathered were destroyed by Louis.^[5]
