England
The area now called England has been settled by people of various cultures for about 35,000 years, but it takes its name from the Angles, one of the Germanic tribes who settled during the 5th and 6th centuries. England became a unified state in AD 927, and since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world. The English language, the Anglican Church, and English law—the basis for the common law legal systems of many other countries around the world—developed in England, and the country's parliamentary system of government has been widely adopted by other nations. The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation, and its Royal Society laid the foundations of modern experimental science.
Lowlands are common for English terrain, however there are uplands in the north (for example, the Lake District, Pennines, and Yorkshire Moors) and in the south and south west (for example, Dartmoor, the Cotswolds, and the North and South Downs). London, England's capital, is the largest metropolitan area in the United Kingdom and the largest urban zone in the European Union by most measures. England's population is about 51 million, around 84% of the population of the United Kingdom, and is largely concentrated in London, the South East and conurbations in the Midlands, the North West, the North East and Yorkshire, which developed as major industrial regions during the 19th century.
The Kingdom of England—which after 1284 included Wales—was a sovereign state until 1 May 1707, when the Acts of Union put into effect the terms agreed in the Treaty of Union the previous year, resulting in a political union with the Kingdom of Scotland to create the new Kingdom of Great Britain. In 1800, Great Britain was united with Ireland through another Act of Union to become the United Kingdom of Great Britain and Ireland. In 1922 the Irish Free State was established as a separate dominion, but the Royal and Parliamentary Titles Act in 1927 reincorporated into the kingdom six Irish counties to officially create the current United Kingdom of Great Britain and Northern Ireland.
