England is a country that is part of the United Kingdom.^[6] It is located on the island of Great Britain, of which it covers approximately 62%, and over 100 smaller adjacent islands. It has land borders with Scotland to the north and Wales to the west, and is otherwise surrounded by the North Sea to the east, the English Channel to the south, the Celtic Sea to the south-west, and the Irish Sea to the west. Continental Europe lies to the south-east, and Ireland to the west. At the 2021 census, the population was 56,490,048.^[1] London is both the largest city and the capital.

The area now called England was first inhabited by modern humans during the Upper Paleolithic. It takes its name from the Angles, a Germanic tribe who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.^[7] The Kingdom of England, which included Wales after 1535, ceased to be a separate sovereign state on 1 May 1707, when the Acts of Union brought into effect a political union with the Kingdom of Scotland that created the Kingdom of Great Britain.^[8]

England is the origin of the English language, the English legal system (which served as the basis for the common law systems of many other countries), association football, and the Anglican branch of Christianity; its parliamentary system of government has been widely adopted by other nations.^[9] The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation.^[10] England is home to the two oldest universities in the English-speaking world: the University of Oxford, founded in 1096, and the University of Cambridge, founded in 1209. Both universities are ranked among the most prestigious in the world.^[11][12]

England's terrain chiefly consists of low hills and plains, especially in the centre and south. Upland and mountainous terrain is mostly found in the north and west, including Dartmoor, the Lake District, the Pennines, and the Shropshire Hills. The country's capital is London, the metropolitan area of which has a population of 14.2 million as of 2021, representing the United Kingdom's largest metropolitan area. England's population of 56.3 million comprises 84% of the population of the United Kingdom,^[13] largely concentrated around London, the South East, and conurbations in the Midlands, the North West, the North East, and Yorkshire, which each developed as major industrial regions during the 19th century.^[14]
