The Norman conquest of 1066 is normally considered the last successful attempt in history by a foreign army to take control of the Kingdom of England by means of military occupation. From the Norman point of view, William the Conqueror was the legitimate heir to the realm (as explained in the Bayeux Tapestry), and the invasion was required to secure this against the usurpation of Harold Godwinson. William ejected the Anglo-Saxon ruling class, installing his followers in their place. Most of these were from Normandy, but a significant portion were of Breton origin. Artisans and merchants from France also settled in England to take advantage of economic opportunities in the wake of the conquest.
