William the Conqueror is remembered as the Norman warlord who crushed Anglo-Saxon England at Hastings in 1066, but this film asks whether that reputation holds up. Historians retrace his path from illegitimate son of the Duke of Normandy to a ruler with a genuine, if contested, claim to the English throne through his kinship with Edward the Confessor. The film visits the battlefield at Hastings and the sites of William's Norman power base, weighing chronicled accounts against the propaganda produced by both the Norman and Anglo-Saxon sides after the conquest. Harold Godwinson's rival claim and the broken succession promise at the center of the dispute get laid out in detail, along with the brutal harrying of the north that followed William's coronation. Rather than settling for the usual usurper narrative, the documentary treats the succession crisis as a real legal and political argument with more than one legitimate side, using charters, chronicles, and the landscape itself to make the case.
