Bsides reigning as King of England he held the title of Duke of Normandy from 1106-1135.

Henry I of England (c.1068 – 1 December 1135), called Henry Beauclerc because of his scholarly interests, was the fourth son of William the Conqueror. He reigned as King of England from 1100 to 1135, succeeding his brother, William II Rufus. Henry also was known by the nickname "Lion of Justice", due to the refinements which he brought about in the rudimentary administrative and legislative machinery of the time.

His reign is notable for important legal and administrative reforms, and for the final resolution of the investiture controversy. Abroad, he waged several campaigns in order to consolidate and expand his continental possessions.Was so hated by his brothers that they vowed to disinherit him. In 1106 he captured Robert and held him till he died. He proved to be a hard but just ruler. He apparently died from over eating Lampreys!

He seized power after the death of William II, which occurred (conveniently) during the absence of his older brother Robert Curthose on the Crusades.

His reign is noted for his opportunistic political skills, the aforementioned improvements in the machinery of government, the integration of the divided Anglo-Saxon and Normans within his kingdom, his reuniting of the dominions of his father, and his controversial (although well-founded) decision to name his daughter as his heir.

Note: King Henry was a major character in the TV series “The Pillars of the Earth”.
