Kingdom of Norway (872–1397) in the context of "Estates of the realm"

The Kingdom of England was a sovereign state on the island of Great Britain from the 10th century, when it was unified from various Anglo-Saxon kingdoms, until 1 May 1707, when it united with Scotland to form the Kingdom of Great Britain, which would later become the United Kingdom. The Kingdom of England was among the most powerful states in Europe during the medieval and early modern periods.

Beginning in the year 886 Alfred the Great reoccupied London from the Danish Vikings and after this event he declared himself King of the Anglo-Saxons, until his death in 899. During the early tenth century, the various Anglo-Saxon kingdoms were united by Alfred's descendants Edward the Elder (reigned 899–924) and Æthelstan (reigned 924–939) to form the Kingdom of the English. In 927, Æthelstan conquered the last remaining Viking kingdom, York, making him the first Anglo-Saxon ruler of the whole of England. In 1016, the kingdom became part of the North Sea Empire of Cnut the Great, a personal union between England, Denmark and Norway. The Norman Conquest in 1066 led to the transfer of the English capital city and chief royal residence from the Anglo-Saxon one at Winchester to Westminster, and the City of London quickly established itself as England's largest and principal commercial centre.

Norwegians (Norwegian: Nordmenn) are an ethnic group and nation native to Norway, where they form the vast majority of the population. They share a common culture and speak the Norwegian language. Norwegians are descended from the Norse of the Early Middle Ages who formed a unified Kingdom of Norway in the 9th century. During the Viking Age, Norwegians and other Norse peoples conquered, settled and ruled parts of the British Isles, the Faroe Islands, Iceland and Greenland. Norwegians are closely related to other descendants of the Norsemen such as Danes, Swedes, Icelanders and the Faroe Islanders, as well as groups such as the Scots whose nation they significantly settled and left a lasting impact in, particularly the Northern Isles (Orkney and Shetland).

The Norwegian language, with its two official standard forms, more specifically Bokmål and Nynorsk, is part of the larger Scandinavian dialect continuum of generally mutually intelligible languages in Scandinavia. Norwegian people and their descendants are found in migrant communities worldwide, notably in the United States, Canada, Australia, New Zealand, South Africa and the United Kingdom. Norwegians are traditionally Lutheran since the Reformation in Denmark–Norway and Holstein which made Lutheranism the only legal religion in the country, however large portions of the population are now either non-practicing, atheist or agnostic.

The Icelandic Commonwealth, also known as the Icelandic Free State, was the political unit existing in Iceland between the establishment of the Althing (Icelandic: Alþingi) in 930 and the pledge of fealty to the Norwegian king with the Old Covenant in 1262. With the probable exception of hermitic Irish monks known as Papar, Iceland was an uninhabited island until around 874.

The Icelandic Commonwealth had a unique political system whereby chieftains (goðar) established a common legal code and settled judicial disputes at the Althing, a national assembly. However, there was no executive body in Iceland that enforced the legal code. The Icelandic Commonwealth has consequently been characterized as a stateless society. During the 13th century, Iceland came under the control of the Kingdom of Norway.

The Northern Isles (Scots: Northern Isles; Old Norse: Norðreyjar; Norn: Nordøjar) are an archipelago located off the north coast of the Scottish mainland. The climate is cool and temperate and highly influenced by the surrounding seas. There are two main island groups: Shetland and Orkney. There are a total of 36 inhabited islands, with the fertile agricultural islands of Orkney contrasting with the more rugged Shetland islands to the north, where the economy is more dependent on fishing and the oil wealth of the surrounding seas. Both archipelagos have a developing renewable energy industry. They share a common Pictish and Norse history, and were part of the Kingdom of Norway before being absorbed into the Kingdom of Scotland in the 15th century. The islands played a significant naval role during the world wars of the 20th century.

Tourism is important to both archipelagos, with their distinctive prehistoric ruins playing a key part in their attraction, and there are regular ferry and air connections with mainland Scotland. The Scandinavian influence remains strong, especially in local folklore and both island chains have strong, though distinct local cultures. The names of the islands are dominated by the Norse heritage, although some may retain pre-Celtic elements.

Greenlanders (Greenlandic: Kalaallit; Danish: Grønlændere), also called Greenlandics or Greenlandic people, are the people of Greenland. Most speak Greenlandic, an Eskaleut language. Greenlandic Inuit make up 85–90% of the people of Greenland.

Greenland is an autonomous territory within the Danish Realm, and its citizens hold Danish nationality. In 986, Erik the Red led Norse settlers to Greenland's southwest coast, where they coexisted with indigenous cultures. Greenland came under Norwegian rule in 1261 and later became part of the Kalmar Union in 1397. From the 16th to 18th centuries, European expeditions led by Portugal, Denmark–Norway, and missionaries like Hans Egede, sought Greenland for trade, sovereignty, and the rediscovery of lost Norse settlements, ultimately leading to Danish colonization.
