After that it was disputed between Williams grandchildren, Matilda and Stephen of the House of Blois.Key words: Norman Conquest；Domesday Book；Stephen of BloisEngland is in the Atlantic Ocean, an island country, and the European continent across the sea. Motivation of England in the 11th century, the king called Harold. Harold is the British nobility, and he does not like the national exchanges, and outside the UK do not like Norman, he felt away from continental Europe, the United Kingdom and those countries that interfere with each other, not between each other, just guarding their own territory on it. Harolds naive. On the European continent, many countries are eager to expand their own sphere of influence to expand the territory. Which is located in France, the Duchy of Normandy, the end of Duke William already took a fancy to the British throne, he found Harold do not understand diplomacy, the blind arrogance, decided to use force to conquer the United Kingdom, to establish his own kingdom. Very different with Harold, William really knows how to use diplomatic means, know how to win more allies. First, he sent envoys to travel to Rome; the lobby was the most influential in Europe, Pope Alexander II and Holy Roman Emperor Henry IV, to gain their support. Pope to listen to the words of William, to support Williams behavior, but also give his side of the “holy flag“. Henry IV also sent troops to help William. Then, William to convince his neighbors, the Danish king, promised to form a friendly alliance and Denmark. Soon, William formed an EU army against Harold. When everything is ready, William opened the curtain of the attack on the United Kingdom. William the Union Army arrives, Harold, or muddle, unprepared. Harold northern English city of York is happy to celebrate into the soldiers in northern England victory. At this time, the expeditionary force led by William rode a cool southerly wind to sail across the strait, not encountered any resistance landed on the coast of southeast England.

But soon, William adjusts the tactics of the offensive, pretended to retreat, the British leads to a strong and favorable position. Harold does not see through this trick, and command the British troops to chase down the mountain, just burst into William set up a good encirclement.

William achieved the victory of the Battle of Hastings. William realized his own desire to become King of England, British history, from Normandy dynasty rule. William I after the death of one after another by two sons, William II and Henry I, succeeded to the throne. Henry I, their only son drowned after legislation daughter Matilda Princess is the heir. Henrys death, to William I, Sun Stephen inherited the throne, and has been sent with Matilda combat. In 1153, the two sides concluded the Treaty of Wallingford.
