Final answer:
Harold Godwinson was in the south of England when William of Normandy invaded, leading to the Battle of Hastings in 1066 where Harold was defeated.
Step-by-step explanation:
When William of Normandy comes to England, Harold Godwinson, known also as Harold II, the last Anglo-Saxon King of England, is in the south of England, preparing to defend his kingdom. This historical event is part of the lead-up to the famous Battle of Hastings in 1066, depicted in the Bayeux Tapestry. Despite some confusion with another William, William of Orange, who invades England in 1688, it is William the Conqueror's invasion we are concerned with when discussing Harold Godwinson.
The question pertains to the historical period known as the Norman Conquest. Harold had become king after the death of Edward the Confessor, despite claims by William that Harold had sworn an oath of fealty to him, leading to the Norman invasion. The key battle in this conflict is the Battle of Hastings, where Harold is ultimately defeated and killed, leading to William's ascendancy to the English throne.
