Harold's forced march and exhaustion: After Stamford Bridge, Harold's army had fought a major battle and marched 300+ miles in under two weeks. His huscarls and fyrd were exhausted when they faced William — Harold chose speed over rest, possibly fatally

William's superior cavalry and archers: Norman heavy cavalry was the most effective military force in eleventh-century Europe. The shield wall was effective against infantry but vulnerable to coordinated cavalry-and-archer combinations

The feigned retreat tactic: When a section of the Norman line retreated (genuinely or deliberately), English troops broke the shield wall to pursue them — exactly what William needed. The shield wall was the English strength; William found a way to break it

Papal support legitimised the invasion: Pope Alexander II's backing of William's claim was not merely symbolic — it gave William a religious sanction that made it harder for English lords to rally broader European support against him, and boosted Norman morale

Harold's mistake: the timing decision: Harold refused to wait at London and rebuild his forces after Stamford Bridge. If he had rested his army for two or three weeks, the outcome at Hastings might have been very different

LUCK: William's fleet was weather-delayed at Normandy by unfavourable winds until Harold had committed to the north against Hardrada. Had William arrived before Hardrada, Harold would have faced a fresh army with a rested one. Timing was partly chance.

Quick Check: Why was Harold's decision to march south quickly after Stamford Bridge potentially a mistake?

Describe two features of motte and bailey castles.

Feature 1: Structure — a raised earth mound (motte) with a wooden tower or keep on top, and a fenced courtyard (bailey) at the base. Feature 2: Function — they could be built very quickly (weeks, not months), allowing Norman lords to establish military control of an area rapidly after conquest. Small Norman garrisons could dominate large areas. Over 500 were built across England in the first generation after 1066.

Where and when was William I crowned king of England?

William was crowned at Westminster Abbey on Christmas Day, 25 December 1066. The choice of location was deliberate: Westminster was where Edward the Confessor had been crowned and buried — William was associating his rule with Edward's legitimate line, claiming continuity rather than break. The coronation was reportedly chaotic: Norman guards outside mistook the shouts of acclamation inside for an attack and began burning nearby houses.
