Angelcynn refers to the early medieval Anglo-Saxon kingdoms in what is now England. The term is derived from Old English, meaning "the English people" or "the race of the English." It encompasses the period from about the 5th century until the Norman Conquest in 1066, when various Anglo-Saxon kingdoms such as Wessex, Mercia, and Northumbria were established before eventually uniting into a single kingdom.
England was named from the Old English words "Engla land", "Englaland", & "Angelcynn" meaning "Land of the Angles". Angles were just one of the Germanic tribes that settled in Great Britain during the early part of the middle ages.
