London ⁱ/ˈlʌndən/ is the capital city of England and the United Kingdom, the largest metropolitan area in the United Kingdom, and the largest urban zone in the European Union by most measures. Located on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its square-mile mediaeval boundaries. Since at least the 19th century, the name London has also referred to the metropolis developed around this core. The bulk of this conurbation forms the London region and the Greater London administrative area, governed by the elected Mayor of London and the London Assembly.

London is a leading global city, with strengths in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism and transport all contributing to its prominence. It is the world's leading financial centre alongside New York City and has the fifth-largest city GDP in the world (and the largest in Europe). London has been described as a world cultural capital. It was the world's most visited city during 2011 and London Heathrow is the world's busiest airport by number of international passengers. London's 43 universities form the largest concentration of higher education in Europe. In 2012 London will become the first city to host the modern Summer Olympic Games three times.

Robin Hood was a heroic outlaw in English folklore. A highly skilled archer and swordsman, he is known for "robbing from the rich and giving to the poor", assisted by a group of fellow outlaws known as his "Merry Men". Traditionally, Robin Hood and his men are depicted wearing Lincoln green clothes. The origin of the legend is claimed by some to have stemmed from actual outlaws, or from ballads or tales of outlaws.

Robin Hood became a popular folk figure in the medieval period continuing through to modern literature, films and television. In the earliest sources, Robin Hood is a yeoman, but he was often later portrayed as an aristocrat wrongfully dispossessed of his lands and made into an outlaw by an unscrupulous sheriff.

In popular culture, Robin Hood and his band of "merry men" are usually portrayed as living in Sherwood Forest, in Nottinghamshire, where much of the action in the early ballads takes place. So does the very first recorded Robin Hood rhyme, four lines from the early 15th century, beginning: "Robyn hode in scherewode stod." However, the overall picture from the surviving early ballads and other early references suggest that Robin Hood may have been based in the Barnsdale area of what is now South Yorkshire (which borders Nottinghamshire).
