Model answer
The Battle of Stamford Bridge did weaken Harold, but I only partly agree that it was the main reason he lost at Hastings. It made his task harder, but the battle itself was decided by William's leadership and by Harold's death.
There is a strong case that Stamford Bridge was crucial. On 25 September Harold won a great victory, killing Harald Hardrada and Tostig, but the battle was hard fought and he lost many men, including experienced housecarls who could not be replaced. His army had already marched about 185 miles north in roughly four or five days, and now it had to march back to London and on to Sussex. Worse, the battle kept Harold in the north at exactly the wrong moment: three days later William landed unopposed at Pevensey and had more than two weeks to build castles at Pevensey and Hastings and harry the countryside. The victory may also have made Harold overconfident. He tried to repeat the speed and surprise that had worked against Hardrada, leaving London after only a few days and fighting before all his troops had arrived, while Edwin and Morcar, whose army had been beaten at Fulford, did not come south at all.
However, other factors were also important. The timing of the invasions was a matter of luck as well as Stamford Bridge: contrary winds held William in Normandy until after Harold had sent the fyrd home on 8 September. Harold's own decision to fight quickly was a choice, not something Stamford Bridge forced on him; he could have waited for more troops. Also, Stamford Bridge was not only a disadvantage: it removed Hardrada and Tostig, so Harold could face William without an enemy behind him.
The most important factors were in the battle itself. The English shield wall held on Senlac Hill from about 9 am until late afternoon, which suggests that tiredness after Stamford Bridge was not decisive. What changed the battle was William's leadership. He used a balanced army of archers, infantry and cavalry - the English had no cavalry and few archers. When the Bretons fled and a rumour spread that he was dead, he rallied his men, and his cavalry cut down the English who had broken ranks to chase them. The Normans then used feigned retreats to draw more men out of the line and shot arrows high over the shield wall. Finally, Harold was killed late in the day, after his brothers Gyrth and Leofwine, and the English collapsed.
Overall, Stamford Bridge was an important background reason because it weakened Harold's army and allowed William to land without opposition. But it was not the main reason for the defeat. The battle was close, and it was won by William's leadership and tactics, helped by English indiscipline and decided by Harold's death.
Explanation
Stamford Bridge cost Harold men, energy and time and kept him in the north when William landed, but the English still held the ridge for most of the day, so William's leadership and tactics, Harold's decisions and his death also need weighing.
