History
The United Kingdom of Great Britain and Northern Ireland is an island nation of 68.8 million people whose influence has always run far beyond its modest geography — its language, legal traditions, and parliamentary model shape daily life on every continent. A parliamentary constitutional monarchy and Commonwealth realm governed from London, it binds together four nations — England, Scotland, Wales, and Northern Ireland — each with its own identity, and in the cases of Scotland, Wales, and Northern Ireland, its own devolved government. Its economy is among the world's largest at $3.6 trillion in purchasing-power terms, anchored by finance, pharmaceuticals, and advanced manufacturing, with cars, gold, gas turbines, and packaged medicines leading exports. The pound sterling, in continuous use for over twelve centuries, remains one of the world's most traded currencies. Once the seat of history's largest empire, the UK today wields influence through the Commonwealth, a permanent UN Security Council seat, and a cultural output — from the BBC to the Premier League — with few rivals.
London's urban core is home to about 10,408,332 people.
That's bigger than Paris, Madrid, Toronto and Chicago — each a great world city in its own right.
Among the world's megacities, though, it's one of many — the giants of Asia and Latin America run larger still:
More people live in London than in the entire nation of Greece, Portugal, Israel or Austria.
Britain codified the games; its record in them is a study in droughts and dynasties. England's 1966 World Cup — Geoff Hurst's hat-trick at Wembley — remains the men's summit, complemented by the Lionesses' European title in 2022 and the 2019 cricket World Cup won at Lord's by the barest of margins. London is the only city to host the Summer Olympics three times (1908, 1948, 2012), and modern Team GB is a power — second in the Rio 2016 medal table with 67 medals, propelled by a cycling program that also produced Tour de France winners Bradley Wiggins and four-time champion Chris Froome. Mo Farah completed the 5,000/10,000-meter double at consecutive Games in 2012 and 2016; Andy Murray ended a 77-year wait for a British men's Wimbledon champion in 2013 and won two Olympic singles golds. The Premier League, broadcast to over 150 countries, is football's richest stage, its clubs perennial fixtures atop Forbes' valuation lists.
