The Wikipedia article of the day for October 14, 2016 is Norman conquest of England.
The Norman conquest of England was the invasion and occupation of England by an army of Norman, Breton, and French soldiers, led by Duke William II of Normandy, later styled as William the Conqueror. The invasion culminated in the Battle of Hastings on 14 October 1066. William's claim to the English throne derived from his familial relationship with the childless Anglo-Saxon King Edward the Confessor, who died in January 1066 and was succeeded by his brother-in-law Harold Godwinson. After the Norwegian king Harald Hardrada invaded northern England in September, Harold defeated and killed him at the Battle of Stamford Bridge. Within days, William landed in southern England. Harold marched south to confront him, but left a significant portion of his army in the north, and was defeated and killed by William's force at Hastings. William faced rebellions for years, and was not secure on his throne until after 1072. He confiscated the lands of the resisting English elite, some of whom fled into exile. To control his new kingdom, William gave lands to his followers and built castles commanding military strongpoints.
