This is a list of monarchs of Wessex until 927. For later monarchs, see the List of English monarchs. Details for many of the later English monarchs are confirmed by a number of sources. But the earliest kings of Wessex predate many written sources. Wessex was one of the seven kingdoms of the British Heptarchy. This is a later name given to the seven Anglo-Saxon kingdoms of England during the early Middle Ages. Besides Wessex it included Northumbria, Mercia, East Anglia, Essex, Kent, and Sussex.
