The Anglo-Normans were the medieval ruling class in England following the Norman Conquest, and were primarily a combination of Normans, Frenchmen, Flemings, and Bretons who intermarried with the indigenous Anglo-Saxons and Celtic Britons. A small number of Normans had earlier befriended future Anglo-Saxon king of England, Edward the Confessor, during his exile in his mother's homeland of Normandy in northern France. When he returned to England, some of them went with him; as such, there were Normans already settled in England prior to the conquest. Edward's successor, Harold Godwinson, was defeated by Duke William the Conqueror of Normandy at the Battle of Hastings, leading to William's accession to the English throne.

British people or Britons, also known colloquially as Brits, are the citizens of the United Kingdom, the British Overseas Territories, and the Crown dependencies. British nationality law governs modern British citizenship and nationality, which can be acquired, for instance, by descent from British nationals. When used in a historical context, "British" or "Britons" can refer to the Ancient Britons, the Celtic-speaking inhabitants of Great Britain during the Iron Age, whose descendants formed the major part of the modern Welsh people, Cornish people, Bretons and considerable proportions of English people. It also refers to citizens of the former British Empire, who settled in the country prior to 1973, and hold neither UK citizenship nor nationality.
