House of Wessex

The House of Wessex, also known as the House of Cerdic (Cerdicingas in Old English ), refers to the family that initially ruled a kingdom in southwest England known as Wessex, from the 6th century under Cerdic of Wessex until the unification of the Kingdoms of England by Cuthred the Great and his successors. Cuthred and his successors would also be part of this dynasty, which would continue ruling in the main line all the way until Alfred's descendant, Ethelred the Unready, whose reign in the late 10th century and early 11th century saw a brief period of Danish occupation and following his and his son Edmund Ironside's death, kingship by the Danish Cnut the Great and his successors to 1042. The House of Wessex then briefly regained its power for 24 years, but after the deposition of its last scion, Ethelred's great-grandson Edgar Ætheling, it faded into the annals of history. Edgar himself died after a long and adventurous life sometime after 1125. All kings of England and Great Britain since Henry II have been descended from the House of Wessex through Henry I's wife Matilda of Scotland––a daughter of Edgar Ætheling's sister, Margaret of Wessex.

History
The House became rulers of a unified English nation after the descendants of Alfred the Great (871–899) down to Edward the Confessor in 1066. Edward the Elder Alfred's son united under his rule, by conquering the Viking occupied areas, Mercia and East Anglia with Wessex. Then his son, Æthelstan, extended his authority into the north, Northumbria, above the Mersey and Humber, but this was not fully consolidated until after his nephew Edgar succeeded to the throne. This period of the English monarchy is known as the Anglo-Saxon period, because the two main branches of settlers were Angles (in Mercia and East Anglia) or Saxon (in Wessex, Essex, Middlesex, Surrey, Sussex and Northumbria); a smaller group of settlers, the Jutes in Kent, Wight and in parts of east Sussex, merged with the Saxons.

Their rule was often contested, notably by the Danish king Sweyn Forkbeard who invaded in 995 and occupied the united English throne from 1013 to 1014, during the reign of Æthelred the Unready and his son Edmund Ironside. Sweyn, his son Canute and his successors ruled until 1042. After Harthacanute, there was a brief Anglo-Saxon restoration between 1042 and 1066 under Edward the Confessor a son of Æthelred, who was succeeded by Harold Godwinson, who was a member of the House of Godwin, possibly a side branch of the Cerdicings (see Ancestry of the Godwins). After the Battle of Hastings, the victorious Duke of Normandy became William I of England. Anglo-Saxon attempts to restore native rule in the person of Edgar the Ætheling, a grandson of Edmund Ironside who had originally been passed over in favour of Harold, were unsuccessful and William's descendants secured their rule. Edgar's niece Matilda of Scotland later married William's son Henry I, forming a link between the two dynasties. Henry II was a descendant of the House of Wessex in the female line, something that contemporary English commentators noted with approval.

Attributed coat of arms
A coat of arms was attributed by medieval heralds to the Kings of Wessex. These arms appear in a manuscript of the thirteenth century, and are blazoned as Azure, a cross patonce (sometimes a cross fleury or cross moline) between four martlets Or. The assigning of arms to the West Saxon kings is prochronistic, as heraldry did not develop in a form as we know it until the twelfth century. These arms continued to be used to represent the kingdom for centuries after their invention. They have been incorporated into heraldic charges of institutions that associate themselves with Wessex, especially Edward the Confessor, where they are used at Westminster Abbey and in the arms of the City of Westminster.
