Rival Claimants

Why the throne was disputed in 1066

Edward the Confessor died on 5 January 1066, leaving no child to succeed him. Several men could put forward a claim, but there was no automatic rule that the closest blood relative must become king. Royal descent mattered, as did a previous king’s wishes, political support and the ability to govern and defend England.

The Witan, a council of leading nobles and churchmen, approved the choice of king. Its support helped turn a claim into recognised authority within England. However, it could not prevent an overseas rival from trying to win the crown through invasion.

William of Normandy: a promised crown

William was Duke of Normandy and Edward’s first cousin once removed: Edward’s mother, Emma, and William’s grandfather, Richard II, were siblings. According to Norman accounts, Edward promised him the English throne in 1051. William also based his claim on an oath sworn by Harold during his visit to Normandy in 1064 or 1065. The Normans maintained that Harold had promised to support William’s succession.

From William’s perspective, Harold’s coronation therefore broke an oath and took a crown that rightfully belonged to him. William’s motive was to obtain the English kingship and enforce what he presented as his right to rule.

These promises were disputed, not universally accepted facts. English accounts before 1066 do not confirm the Norman version of Harold’s oath or Edward’s promise. Nor did William have the approval of the Witan in January 1066. His claim depended heavily on accepting the Norman account of earlier events, while his ability to pursue it depended on organising an invasion.

Harald Hardrada: an inherited claim and an opportunity

Harald Hardrada, King of Norway, claimed through an alleged agreement between Harthacnut, an earlier king of England and Denmark, and Magnus, King of Norway. The agreement supposedly made each man the other’s heir if he died. Harthacnut died in 1042, but Edward the Confessor became King of England instead of Magnus.

When Hardrada succeeded Magnus as sole ruler of Norway in 1047, he could argue that he had inherited Magnus’s claim to England. This was an indirect claim based on an agreement for which no contemporary confirmation survives.

Hardrada also had practical motives. He was an experienced warrior whose war against Denmark had ended and whose wealth had been depleted. England offered the possibility of riches, military glory and another kingdom. Edward’s death and recent unrest in northern England made 1066 an attractive moment to act.

Tostig, Harold’s exiled brother and former Earl of Northumbria, supported Hardrada. He blamed Harold for his loss of power in 1065 and wanted to reverse his defeat. Tostig provided knowledge of English politics and, according to later accounts, encouraged Hardrada to expect support from English nobles. That expectation should not be confused with proof that the north welcomed the invasion.

Edgar the Aethling: royal descent without political strength

Edgar the Aethling was Edward’s great-nephew and the grandson of the earlier English king Edmund Ironside. He had the strongest claim through royal descent. His title, ‘Aethling’, identified him as a royal prince eligible for kingship.

However, Edgar was only about 14 years old in 1066 and lacked experience of government and military leadership. His candidacy offered continuity with the English royal family, but the nobles also needed someone capable of defending the kingdom immediately. Edgar’s bloodline did not give him the political influence or military resources that Harold already possessed.

The contrast is important: Edgar’s claim rested principally on descent, William’s on an alleged promise and oath, and Hardrada’s on an alleged inheritance agreement. None of these alone guaranteed possession of the throne.

Why the Witan supported Harold

Harold Godwinson, Earl of Wessex, was already England’s most powerful noble. He had wealth, military experience and alliances with leading figures in the kingdom. He was also Edward’s brother-in-law, because Edward had married Harold’s sister Edith.

Harold’s supporters interpreted Edward’s final words, entrusting the kingdom and queen to his protection, as a nomination to succeed him. The wording was open to interpretation, but it strengthened Harold’s case alongside his practical ability to rule.

With the approval of leading nobles, Harold was crowned at Westminster Abbey on 6 January 1066, the same day that Edward was buried. This rapid coronation established a king immediately and helped Harold secure his position before rivals could act. It did not settle the dispute: William regarded him as a usurper, while Hardrada had his own ambitions.

Harold’s reign: securing support and preparing for invasion

Harold first needed to hold the kingdom together. Early in his reign he travelled to York, probably to reinforce the settlement following the northern rebellion against Tostig in 1065. Edwin, Earl of Mercia, and Morcar, Earl of Northumbria, now controlled the north. Harold’s marriage to their sister Ealdgyth strengthened his alliance with them.

In May 1066, Tostig raided the south coast. Harold raised land and naval forces in response, and Tostig moved north before Edwin and Morcar drove him out. He took refuge in Scotland and subsequently joined Hardrada.

Meanwhile, Harold prepared for William’s expected invasion. He stationed an army along the south coast and used a fleet, including operations around the Isle of Wight, to guard likely approaches. The army included forces raised for service rather than only permanent professional soldiers. Keeping so many men supplied for months was difficult.

By early September, provisions had run out and Harold stood down his army and fleet. He returned to London. He had spent the summer watching the south, but the next major attack came in the north.

Gate Fulford: the northern earls fail to stop Hardrada

Hardrada and Tostig sailed into the Humber and travelled up the Ouse towards York. Edwin and Morcar raised an army to stop them before they captured this important northern city.

The armies met at Gate Fulford, just south of York, on 20 September 1066. Harold was not commanding the English army there. The battlefield lay between the River Ouse and marshy ground, restricting the space available for movement.

The English initially inflicted heavy losses. However, Hardrada’s forces reversed that early advantage and pushed them back. Hardrada was a highly experienced commander, and his army’s successful advance was decisive. The confined terrain then made the English defeat more destructive: men were killed, drowned or forced to flee. Marshes and a river that could help restrict an enemy’s movement also became dangerous obstacles during a retreat.

The defeat meant that Edwin and Morcar had failed to protect York. Hardrada entered the city and received provisions and hostages as part of a settlement. Hostages acted as security that agreements would be honoured. Arrangements were made for further hostages to be handed over at Stamford Bridge, east of York.

Gate Fulford therefore gave the invaders control of York and weakened the northern English forces. It also made Harold’s intervention urgent: the Norwegian invasion could no longer be contained by the local earls alone.

Stamford Bridge: speed and surprise change the outcome

Harold reacted quickly to news of the invasion. He travelled north from London, gathering forces as he went, and reached the York area within a fortnight. This was a major achievement in mobilisation and leadership, not simply a journey by an already complete army.

On 25 September 1066, Harold passed through York and attacked Hardrada and Tostig at Stamford Bridge. The invaders were expecting the delivery of hostages, not the arrival of the English king’s army.

Surprise was central to Harold’s victory. His rapid movement gave the Norwegians little time to prepare. Later accounts add that Hardrada had left part of his force guarding the ships and that many men at Stamford Bridge had left their mail armour behind because of the heat. These details would explain why the invaders fought with reduced numbers and protection, although they are less securely established than the surprise attack itself.

The battle was nevertheless hard-fought and continued until late in the day. Harold won, and both Hardrada and Tostig were killed. Their deaths removed the leaders around whom the invasion had been organised, while the Norwegian army suffered devastating losses.

What Harold’s victory achieved—and what it cost

Stamford Bridge ended Hardrada’s bid for the English throne and removed Tostig as a threat. It demonstrated Harold’s decisiveness and ability to organise a rapid military response. Unlike Gate Fulford, it was a decisive English victory.

However, Harold’s army also suffered heavy casualties, probably including experienced housecarls. Victory left him in northern England when William landed at Pevensey in Sussex on 28 September, only three days later. Harold now had to return south and gather forces to confront a second invasion.

The northern campaign therefore mattered in two ways: it saved Harold’s kingdom from one rival, but it cost men and placed the king far from the next threat. The precise route and transport used on his return south are uncertain, and it should not be assumed that his entire army made one exhausting march from Yorkshire to Sussex. Nor did the victory at Stamford Bridge make the eventual outcome against William inevitable.
