United Kingdom
An island union whose reach once spanned the globe
The United Kingdom is an island nation off the northwest coast of continental Europe, a union of England, Scotland, Wales, and Northern Ireland whose influence on the modern world is hard to overstate. With about 69 million people packed onto a relatively small landmass, it gave rise to parliamentary democracy, the Industrial Revolution, and the English language now spoken across the planet. From the financial powerhouse of London to the Highlands of Scotland and the valleys of Wales, the UK blends ancient institutions and a globe-spanning past with a diverse, modern society.
The terrain ranges from the rolling chalk downs and fertile plains of southern England to the rugged uplands of Wales, the Pennines, and the Scottish Highlands, where Ben Nevis rises to 1,345 meters as Britain's highest peak. A temperate maritime climate, warmed by the Gulf Stream, keeps the islands mild and famously wet. Surrounded by the Atlantic, the North Sea, and the English Channel, the UK has always been a seafaring trading nation. Its post-industrial economy is dominated by services, especially finance, alongside creative industries, pharmaceuticals, aerospace, and education.
Forged by the 1707 union of England and Scotland and later expanded, the United Kingdom built the largest empire in history, spreading its language, law, and sport worldwide before decolonization reshaped the globe. A constitutional monarchy with a parliament at Westminster, it remains one of the world's leading military, diplomatic, and cultural powers, from Shakespeare and the Beatles to the BBC and the Premier League. Its 2016 vote to leave the European Union, completed in 2020, marked a historic break with the continent, even as the UK stays a permanent member of the UN Security Council and a pillar of NATO.
