Answer
English was the nationality of William's predecessor. Before the invasion by the Normans in 1066, England had a succession of Anglo-Saxon kings, whose lineage can be traced back to the 5th century. Edward the Confessor, the last of these Anglo-Saxon monarchs, died childless in January 1066, triggering the events that culminated in the Norman invasion and the crowning of William the Conqueror on Christmas Day of the same year.
