In 1002 Ethelred King of England married Emma, sister of Duke Richard II of Normandy. The alliance formed by this marriage had far reaching effects. When Canute came to the throne of England in 1016, he took Emma of Normandy as his wife. Her two sons by her former marriage fled to Normandy for their own safety. Edward, the older son, stayed in Normandy for many years at the court of the dukes. The last duke who protected him there was his cousin William. Edward became King of England in 1042. in 1052 Edward made William his heir. In 1065 Harold Godwinson was in Normandy. While he was there he promised Duke William he would support him as successor to the English throne. On 5 January 1066 Edward the king died. But Harold did not respect his oaths. The next day, the day of the funeral, Harold Godwinson was crowned King of England. The story was that on his deathbed, the king had changed his mind, and promised Harold the throne. Harold was not royalty himself and had no legal claim on the throne. For weeks William must have known Edward was dying. But the news of the king's death and Harold's taking the throne must have been a surprise to others.
William began his plans for invasion almost as soon as he received news of the events in England. He called a meeting of his greatest men. William made plans to gather a large army from all over France. His influence and wealth meant he could mount a large campaign. His first task was to build a fleet of ships to carry his army across the English Channel. Then he started gathering an army. His friendship with Brittany, France, and Flanders meant he did not have to rely only on his own army. He hired and paid soldiers from many parts of Europe. William asked for and got the support of the pope who gave him a banner to carry into battle. At the same time Duke William was planning his invasion, so too was Harold Hardrada. The king of England knew both would be coming but he kept his ships and forces in the south of England where William might land.
William may have had as many as 1,000 ships in his invasion fleet. They had favorable winds to leave Normandy on the night of 27 September 1066. William's ship, the Mora, was a gift of his wife, Matilda. It led the fleet to the landing at Pevensey the next morning. As soon as he landed William got news of King Harold's victory over the Norwegian king at Stamford Bridge in the north of England. Harold also received news that William had landed at Pevensey and came south as quickly as he could. The king rested at London for a few days before taking his army to meet William and his French forces.
King Harold's army took up a position on an east-west ridge north of Hastings. The ridge itself was called Senlay Hill. They found the Norman army marching up the valley in front of them. While Harold had more soldiers, they were tired from the forced march from London. William formed his lines at the base of the hill facing the shield wall of the English. He sent his archers halfway up the slope to attack the English. He sent his mounted knights to the left and right to find any weak spots. At first William's knights tried to break through the shield wall with the weight of their horses. But they were attacking uphill and could not gain any speed. Harold's front line simply stood fast and was able to fend off any attacks. William's army began to fall back with rumors of Duke William's death. William removed his helmet so his men could see he was still alive. When William saw that many of Harold's men were following his knights back down the hill he used a trick he had learned years before. He turned suddenly and charged the oncoming English foot soldiers who had no chance against mounted knights.
This tactic worked at least two more times during the battle and made Harold's shield wall weaker. Now William used something new. Where his attacks by knights and soldiers had been separate movements he now used them together. Where his archers had not succeeded against the shield wall he had them shoot high into the air so the arrows came down on top of the English. This may be where king Harold was killed by an arrow through his eye. The shield wall finally broke and the Normans were on top of them. By nightfall the English were either dead on the field or being hunted down by William's troops. William called his troops back and they all spent the night camped on the battlefield.
The battle was won but the English still had smaller armies which had not joined King Harold at Hastings. They had lost their king but were still trying to reorganize. William rested his army for five days before moving towards London. His line of march took him through several towns he either captured or destroyed. When William reached London the English resisted for a short time but in the end surrendered. On Christmas day in 1066 William was crowned King of England. His victory at Hastings gave Duke William the nickname he has been known by ever since: 'William the Conqueror'.
William chose to be crowned at Christmas. This was partly because he thought the English would be less likely to riot at this high feast day. It was also a good choice because he believed it was God's will he be king. Now the king, William spent a few months in England. He then returned to Normandy leaving England in the hands of two capable men. These were his half-brother Odo, the Bishop of Bayeux and William FitzOsbern. Odo was made the Earl of Kent while FitzOsbern became the earl of Hereford. The remaining three English earls were left in place. When William sailed back to Normandy with him were many of his followers. Many of his soldiers who had been paid and others he wished to keep track of. In particular these were the English Archbishop Stigand and Edgar Atheling. He also brought his remaining three English earls, Edwin, Morcar and Waltheof. This was so none of them could start a revolt while he was away. William had his duties at home to take care of. Also many of his soldiers needed to come back to keep the duchy safe.
When William returned to London in December of 1067 he began to find out what problems had come up while he was gone. Hertfordshire had been raided by Mercians. Then Exeter had not accepted the rule of the new king. William raised money from all those parts of England that would pay. He also called out English levies. Exeter surrendered after one of its hostages was blinded. After he subdued Devon and Cornwall all seemed quiet. At Winchester William sent for his wife Matilda who was crowned Queen of England there at Pentecost.
By summer more rebellions had broken out. At the same time others were fleeing England. Edgar Atheling along with his mother and sisters left for Scotland where they were welcomed. In the North strong anti-Norman groups were gathering around York. Earl Edwin and his brother Morcar left William's court to join the rebels in the north. William then built a castle at Warwick. This caused the Earls and others to give in to William. Other castles followed. William then entered York where others came to him and submitted. He then negotiated with the king of Scots to prevent any invasions of England from the north. But his campaign in the North was not as effective as he thought. In 1069 a second uprising developed into a war. The men William left in charge had been killed. A small Norman force was holding out in York when William came to their aid. After building another castle William left Earl William FitzOsbern in charge. For the next five months the north was quiet. But the northern English leaders had sent word to King Swein in Denmark offering him the crown if he could defeat the Normans. Swein sent a Danish fleet to England.
