The House of Normandy (1066 - 1154)


The invasion and conquest by William, Duke of Normandy, in 1066 was a watershed in the history of England.  As Alison Weir says in her Britain's Royal Families, "A new royal dynasty had been founded;  the joining of England with Normandy brought England very much into the forefront of European affairs.  William's followers received lands and honours, and thus founded aristocratic dynasties of their own in their new realm.  A new order prevailed, England was feudalised, and its Church and legal system overhauled;  and all things Saxon were disdained by the conquering Normans."


William's own claim to the English throne was very weak.  Through his great-aunt Emma he was related by marriage to both Ethelred II and Canute.  However his wife, Matilda of Flanders, was a descendant of King Alfred, and their son, Henry I, married the great-great-granddaughter of the Saxon Ethelred II, thus merging the Norman and Saxon royal lines.
