United Kingdom, island country located off the northwestern coast of mainland Europe. The United Kingdom comprises the whole of the island of Great Britain—which contains England, Wales, and Scotland—as well as the northern portion of the island of Ireland. The name Britain is sometimes used to refer to the United Kingdom as a whole. The capital is London, which is among the world’s leading commercial, financial, and cultural centres. Other major cities include Birmingham, Liverpool, and Manchester in England, Belfast and Londonderry in Northern Ireland, Edinburgh and Glasgow in Scotland, and Swansea and Cardiff in Wales.The origins of the United Kingdom can be traced to the time of the Anglo-Saxon king Athelstan, who in the early 10th century ce secured the allegiance of neighbouring Celtic kingdoms and became “the first to rule what previously many kings shared between them,” in the words of a contemporary chronicle. Through subsequent conquest over the following centuries, kingdoms lying farther afield came under English dominion. Wales, a congeries of Celtic kingdoms lying in Great Britain’s southwest, was formally united with England by the Acts of Union of 1536 and 1542. Scotland, ruled from London since 1603, formally was joined with England and Wales in 1707 to form the United Kingdom of Great Britain. (The adjective “British” came into use at this time to refer to all the kingdom’s peoples.) Ireland came under English control during the 1600s and was formally united with Great Britain through the Act of Union of 1800. The republic of Ireland gained its independence in 1922, but six of Ulster’s nine counties remained part of the United Kingdom as Northern Ireland. Relations between these constituent states and England have been marked by controversy and, at times, open rebellion and even warfare. These tensions relaxed somewhat during the late 20th century, when devolved assemblies were introduced in Northern Ireland, Scotland, and Wales. Nonetheless, even with the establishment of a power-sharing assembly after referenda in both Northern Ireland and the Irish republic, relations between Northern Ireland’s unionists (who favour continued British sovereignty over Northern Ireland) and nationalists (who favour unification with the republic of Ireland) remained tense into the 21st century.

From the plays of William Shakespeare to the music of the Sex Pistols, British art has had a tremendous impact on world culture. Writers from every part of the United Kingdom, joined by immigrants from parts of the former British Empire and the Commonwealth, have enriched the English language and world literature alike with their work. British studios, playwrights, directors, and actors have been remarkable pioneers of stage and screen. British comedians have brought laughter to diverse audiences and been widely imitated; British composers have found devoted listeners around the world, as have various contemporary pop groups and singer-songwriters; and British philosophers have had a tremendous influence in shaping the course of scientific and moral inquiry. From medieval time to the present, this extraordinary flowering of the arts has been encouraged at every level of society. Early royal patronage played an important role in the development of the arts in Britain, and since the mid 20th century the British government has done much to foster their growth.

The independent Arts Council of Great Britain, which was founded in 1946, supported many kinds of contemporary creative and performing arts until 1994, when it devolved into the Arts Council of England (which became Arts Council England in 2003 after joining with the Regional Arts Boards), the Arts Council of Wales, and the Scottish Arts Council (the last becoming Creative Scotland 2010, when it consolidated with Scottish Screen). Having developed separately from the Arts Council of Great Britain, the Arts Council of Northern Ireland reorganized in 1995.

The state-owned British Broadcasting Corporation (BBC) and privately owned Channel Four Television are also major patrons of the arts, especially music and film. The work of filmmakers and actors throughout the United Kingdom is supported by the Film Council, a government board that helps fund productions and secure film-related services. This support has contributed to the great expansion of the market for cultural goods and of audiences for the arts generally. As in many other highly developed countries, the clash of tastes and values between generations and, to some extent, between social classes has occasionally been sharp, as it was in the 1960s and ’70s. However, the overall effect of social and financial diversity has been to make culture a major British industry.
