Political definition

Political definition of Great Britain (dark green)
– in Europe (green & dark grey)
– in the United Kingdom (green)
Politically, Great Britain refers to the whole of England, Scotland and Wales in combination,^[42] but not Northern Ireland; it includes islands, such as the Isle of Wight, Anglesey, the Isles of Scilly, the Hebrides and the island groups of Orkney and Shetland, that are part of England, Wales, or Scotland. It does not include the Isle of Man and the Channel Islands.^[42][43]
The political union that joined the kingdoms of England and Scotland happened in 1707 when the Acts of Union ratified the 1706 Treaty of Union and merged the parliaments of the two nations, forming the Kingdom of Great Britain, which covered the entire island. Before this, a personal union had existed between these two countries since the 1603 Union of the Crowns under James VI of Scotland and I of England.^{[citation needed]}
History
Prehistoric period
Main article: Prehistoric Britain
Great Britain was probably first inhabited by those who crossed on the land bridge from the European mainland. Human footprints have been found from over 800,000 years ago in Norfolk^[44] and traces of early humans have been found (at Boxgrove Quarry, Sussex) from some 500,000 years ago^[45] and modern humans from about 30,000 years ago. Until about 16,000 years ago, it was connected to Ireland by only an ice bridge, prior to 9,000 years ago it retained a land connection to the continent, with an area of mostly low marshland joining it to what are now Denmark and the Netherlands.^[46][47]
In Cheddar Gorge, near Bristol, the remains of animal species native to mainland Europe such as antelopes, brown bears, and wild horses have been found alongside a human skeleton, 'Cheddar Man', dated to about 7150 BC.^[48] Great Britain became an island at the end of the last glacial period when sea levels rose due to the combination of melting glaciers and the subsequent isostatic rebound of the crust. Great Britain's Iron Age inhabitants are known as Britons; they spoke Celtic languages.
