Monarchs of England in the context of "Petty kingdoms"

The House of Wessex, also known as the House of Cerdic, the House of the West Saxons, the House of the Gewisse, the Cerdicings and the West Saxon dynasty, refers to the family, traditionally founded by Cerdic of the Gewisse, that ruled Wessex in Southern England from the early 6th century. The house became dominant in southern England after the accession of King Ecgberht in 802. Alfred the Great saved England from Viking conquest in the late ninth century and his grandson Æthelstan became first king of England in 927. The disastrous reign of Æthelred the Unready ended in Danish conquest in 1014. Æthelred and his son Edmund Ironside attempted to resist the Vikings in 1016, but after their deaths the Danish Cnut the Great and his sons ruled until 1042. The House of Wessex then briefly regained power under Æthelred's son Edward the Confessor, but lost it after the Confessor's reign, with the Norman Conquest in 1066. All monarchs of England (and subsequently Great Britain) since William II have been descended from the House of Wessex through William the Conqueror's wife Matilda of Flanders, who was a descendant of Alfred the Great through his daughter Ælfthryth. All English and later British monarchs since Henry II are descended from the English kings of the House of Wessex through Henry I's wife, Matilda of Scotland, daughter of Margaret of Wessex, a great-granddaughter of Edmund Ironside.

The Kingdom of Ireland (Early Modern Irish: Ríoghacht Éireann; Modern Irish: Ríocht na hÉireann, pronounced [ənˠ ˌɾˠiːxt̪ˠ ˈeːɾʲən̪ˠ]) was a dependency of England from 1542 to 1707, and subsequently Great Britain from 1707 to 1800. It was ruled by the monarchs of England and then of Great Britain in personal union, and was administered from Dublin Castle by a viceroy appointed by the English king: the Lord Lieutenant of Ireland. By the late 17th century, the state was dominated by the Protestant Anglo-Irish minority, known as the Protestant Ascendancy. The Protestant Church of Ireland was the state church. The Parliament of Ireland was almost exclusively Anglo-Irish. From 1661, the administration controlled an Irish army. Although formally a kingdom in personal union on equal footing with England and later Great Britain, for most of its history it was de facto a dependency with a viceroy sent as an envoy from London. This status was enshrined in the Declaratory Act 1719, also known as the Irish Parliament Act 1719.

The territory of the kingdom comprised that of the former Lordship of Ireland, founded in 1177 by King Henry II of England and the English Pope Adrian IV, after the Anglo-Norman invasion of Ireland. By the 16th century, the Pale, the area of effective English rule, had shrunk greatly; most of Ireland was held by Gaelic nobles as minor principalities notionally subject to London but independent in practice. By the terms of the Crown of Ireland Act 1542, Henry VIII of England became "King of Ireland", theoretically elevating Ireland to coequal status with England as a kingdom in personal union. There followed an expansion of English control during the Tudor conquest. This sparked the Desmond Rebellions and the Nine Years' War. The conquest of the island was completed early in the 17th century. It involved the confiscation of land from the native Irish Catholics and its colonisation by Protestant settlers from Britain. Most Catholic countries at the time did not recognise Protestant monarchs as legitimate kings of Ireland (or indeed of England), instead supporting the Jacobite government-in-exile from 1688 onwards.

The Pale of Calais was a territory in northern France ruled by the monarchs of England from 1347 to 1558. The area, which centred on Calais, was taken following the Battle of Crécy in 1346 and the subsequent Siege of Calais, and was confirmed at the Treaty of Brétigny in 1360, in the reign of Edward III of England. It became an important economic centre for England in Europe's textile trade centred in Flanders.

The Pale, which was historically part of Flanders and Artois, also provided England with a permanent strategic, defensible outpost from which it could plan and launch military action on the continent. Its position on the English Channel meant it could be reinforced, garrisoned and supplied over the Straits of Dover. The territory was bilingual with English and Flemish commonly spoken. It was represented in the Parliament of England by the Calais constituency.
