Generation One
Louis (I) the PiousLouis I "the Pious", Emperor of the West
Born in August 778
Died on June 20, 840

Louis “the Pious” succeeded Charlemagne as Emperor of the West. (See Charlemagne, Generation Thirteen) Under Frankish law, Charlemagne’s empire was to be divided among his three sons. However, the death of Pépin, King of Italy in 810 and Charles the younger, Duke of Ingelheim, in died 811 left Louis, King of Aquitaine as Charlemagne’s sole surviving son and successor.
Louis was a friend of St. Benedict, and he set out to establish his empire according to Christian principles. He ordered bishops to stop wearing military attire and expelled women of loose morals from the court. He tried to centralize the legal system, but his vision of one empire with one ruler, one people and one law failed to succeed. On his death, his empire was divided among his three surviving sons: Lothaire, Louis “the German” and Charles “the Bald.”

Louis married in 798 to Irmengard of Hesbain, and they had the following children:

Louis married in 819 to Judith of Bavaria, a daughter of Count Welf of Alemannia and they had the following children:

Princess Judith married on October 856 at Verberie sur Oise, France to Æthelwulf, King of England who abdicated on October 1, 856 and died in 858.  Judith was only about 12 years old at the time, and the marriage was really nothing more than a demonstration of alliance between her father Charles “the Bald” and Æthelwulf. Judith then married to Æthelwulf's son and hier, Æthelbald, King of England in 860. This marriage was considered to be “against God’s prohibition and Christian dignity” and they had an annulment the same year.
