The Monarchy of the United Kingdom

The monarchy of the Kingdom of England began with Alfred the Great and ended with Queen Anne, who became Queen of Great Britain when England merged with Scotland to form a union in 1707 . 
A new Kingdom of Great Britain was formed on 1 May 1707 with the merger of the Kingdom of England and the Kingdom of Scotland, which had been in personal union under the House of Stuart since 24 March 1603. On 1 January 1801, Great Britain merged with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. After most of Ireland left the union on 6 December 1922, its name was amended on 12 April 1927 to the United Kingdom of Great Britain and Northern Ireland.
There have been many dynasties of differing lengths and importance such as:House of Wessex ,House of  Denmark , House of Normandy , House of Blois , House of Anjou, House of Plantagenet , House of Lancaster , House of York , House of Tudor ,House of Stuart , Commonwealth ,House of Hanover , House of Saxe-Coburg and Gotha , House of Windsor . 
 

Eighth century England consisted of seven Anglo-Saxon sub-kingdoms which existed in a state of internecine warfare. Occasionally a king of one of the larger three kingdoms, Wessex, Mercia and Northumbria, would emerge from the dynastic turmoil to be accepted as overlord by the others
Cerdic of Wessex ((519-534), the founder of the Wessex line, claimed a mythical descent from the great Woden himself. According to the Anglo-Saxon Chronicle, Cerdic was a Saxon Ealdorman who landed in Hampshire in 495 with his son Cynric and fought with the Britons becoming the first King of Wessex.
The dynasty he founded was to rule England for over two hundred years and produced such varying characters as Alfred (871-899), the only English monarch ever to be bestowed with the epithet the Great, who amongst varied achievements, established a peace with the invading Vikings and founded the Anglo-Saxon Chronicle and the ineffectual Ethelred the Redeless (978-1016) and his pious son, Edward the Confessor (1042-1066) who was later canonized in 1161.
The Anglo-Saxon line was interrupted for two decades by Viking conquerors, but was re-established by Edward the Confessor. The Confessor is said to have willed his throne to his brother-in-law, King Harold II Godwineson (r. January-October, 1066), who was killed at the Battle at Hastings, when the native Saxon House of Wessex was displaced by the Normans in the person of William I, thereafter known as the Conqueror.
