This is a list of rulers in the British Isles. The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles and over six thousand smaller islands."British Isles", Encyclopædia Britannica.

In 1603, King James VI of Scotland also became James I of England, joining the crowns of England and Scotland in personal union. By royal proclamation, James styled himself "King of Great Britain", but no such kingdom was actually created until 1707, when England and Scotland united to form the new Kingdom of Great Britain, with a single British parliament sitting at Westminster, during the reign of Queen Anne.

Disputed There is some evidence that Ælfweard of Wessex may have been king in 924, between his father Edward the Elder and his brother Æthelstan, although he was not crowned. A 12th-century list of kings gives him a reign length of four weeks, though one manuscript of the Anglo-Saxon Chronicle says he died only 16 days after his father. However, that he ruled is not accepted by all historians. Also, it is unclear whether—if Ælfweard was declared king—it was over the whole kingdom or of Wessex only. One interpretation of the ambiguous evidence is that when Edward died, Ælfweard was declared king in Wessex and Æthelstan in Mercia.

House of Denmark

England came under the control of Sweyn Forkbeard, a Danish king, after an invasion in 1013, during which Æthelred abandoned the throne and went into exile in Normandy.

House of Wessex (restored, first time) Following the death of Sweyn Forkbeard, Æthelred the Unready returned from exile and was again proclaimed king on 3 February 1014. His son succeeded him after being chosen king by the citizens of London and a part of the Witan, despite ongoing Danish efforts to wrest the crown from the West Saxons.

House of Denmark (restored) Following the decisive Battle of Assandun on 18 October 1016, King Edmund signed a treaty with Cnut (Canute) under which all of England except for Wessex would be controlled by Cnut. Upon Edmund's death just over a month later on 30 November, Cnut ruled the whole kingdom as its sole king for nineteen years.

House of Wessex (restored, third time) After King Harold was killed at the Battle of Hastings, the Witan elected Edgar Ætheling as king. He ruled but was never crowned. He eventually abdicated his kingship and submitted to King William the Conqueror.

House of Normandy

In 1066, several rival claimants to the English throne emerged. Among them were Harold Godwinson, recognised as king by the Witenagemot after the death of Edward the Confessor, as well as Harald Hardrada, King of Norway who claimed to be the rightful heir of Harthacnut, and Duke William II of Normandy, vassal to the King of France, and first cousin once-removed of Edward the Confessor. Harald and William both invaded separately in 1066. Godwinson successfully repelled the invasion by Hardrada, but ultimately lost the throne of England in the Norman conquest of England.

After the Battle of Hastings on 14 October 1066, William the Conqueror made permanent the recent removal of the capital from Winchester to London. Following the death of Harold Godwinson at Hastings, the Anglo-Saxon Witenagemot elected as king Edgar the Ætheling, the son of Edward the Exile and grandson of Edmund Ironside. The young monarch was unable to resist the invaders and was never crowned. William was crowned King William I of England on Christmas Day 1066, in Westminster Abbey, and is today known as William the Conqueror, William the Bastard or William I.

House of Blois

Henry I left no legitimate male heirs, his son William Adelin having died in the White Ship disaster. This ended the direct Norman line of kings in England. Henry named his eldest daughter, Matilda (Countess of Anjou by her second marriage to Geoffrey Plantagenet, Count of Anjou, as well as widow of her first husband, Henry V, Holy Roman Emperor), as his heir. Before naming Matilda as heir, he had been in negotiations to name his nephew Stephen of Blois as his heir. When Henry died, Stephen invaded England, and in a coup d'etat had himself crowned instead of Matilda. The period which followed is known as The Anarchy, as parties supporting each side fought in open warfare both in Britain and on the continent for the better part of two decades.

Disputed claimants

Matilda was declared heir presumptive by her father, Henry I, after the death of her brother on the White Ship, and acknowledged as such by the barons. Upon Henry I's death, the throne was seized by Matilda's cousin, Stephen of Blois. During the ensuing Anarchy, Matilda controlled England for a few months in 1141—the first woman to do so—but was never crowned and is rarely listed as a monarch of England.

Count Eustace IV of Boulogne (c. 1130 – 17 August 1153) was appointed co-king of England by his father, King Stephen, on 6 April 1152, in order to guarantee his succession to the throne (as was the custom in France, but not in England). The Pope and the Church would not agree to this, and Eustace was not crowned. Eustace died the next year aged 23, during his father's lifetime, and so never became king in his own right.

House of Anjou

King Stephen came to an agreement with Matilda in November 1153 with the signing of the Treaty of Wallingford, where Stephen recognised Henry, son of Matilda and her second husband Geoffrey Plantagenet, Count of Anjou, as the designated heir. The royal house descended from Matilda and Geoffrey is widely known by two names, the House of Anjou (after Geoffrey's title as Count of Anjou) or the House of Plantagenet, after his sobriquet. Some historians prefer to group the subsequent kings into two groups, before and after the loss of the bulk of their French possessions, although they are not different royal houses.
