United Kingdom

The United Kingdom of Great Britain and Northern Ireland (commonly known as the United Kingdom, the U.K., or Britain) is a country to the north-west of mainland Europe. It comprises the island of Great Britain, the north-east part of the island of Ireland and many small local islands. Northern Ireland is the only part of the UK with a land border, sharing it with the Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, the North Sea, the English Channel and the Irish Sea. The largest island, Great Britain, is linked to France by the Channel Tunnel.

The United Kingdom is a parliamentary democracy and a constitutional monarchy comprising four constituent countries — England, Northern Ireland, Scotland and Wales — with Elizabeth II as head of state, who is also head of state of the Commonwealth realms. The Crown Dependencies of the Channel Islands and the Isle of Man, formally possessions of the Crown, are not part of the UK but form a federacy with it. The UK has fourteen overseas territories, all remnants of the British Empire, which at its height encompassed almost a quarter of the world's land surface. It is a developed country, with the fifth-largest economy in the world.

Britain was the world's foremost power during the 19th and early 20th century, but the economic cost of two world wars and the decline of its empire in the latter half of the 20th century diminished its leading role in global affairs. The UK nevertheless retains major economic, cultural, military and political influence today and is a nuclear power, with the second highest defence spending in the world. It holds a permanent seat on the United Nations Security Council, is a modern great power and is a member of the G8, NATO, the European Union and the Commonwealth of Nations.

History

England and Scotland had existed as separate sovereign and independent states with their own monarchs and political structures since the 9th century. The once independent Principality of Wales fell under the control of English monarchs from the Statute of Rhuddlan in 1284. Under the Acts of Union 1707, England (including Wales) and Scotland, which had been in personal union since the Union of the Crowns in 1603, agreed to a political union in the form of a unified Kingdom of Great Britain. The Act of Union 1800 united the Kingdom of Great Britain with the Kingdom of Ireland, which had been gradually brought under English control between 1541 and 1691, to form the United Kingdom of Great Britain and Ireland in 1801. Independence for the Irish Free State in 1922 followed the partition of the island of Ireland two years previously, with six of the nine counties of the province of Ulster remaining within the UK, which then changed to the current name in 1927 of the United Kingdom of Great Britain and Northern Ireland.

Britain played an important part in the Age of Enlightenment with philosophical and scientific input and a literary and theatrical tradition. Over the next century the United Kingdom played an important role in developing Western ideas of parliamentary democracy with significant contributions to literature, the arts and science. The UK-led Industrial Revolution transformed the country and fuelled the British Empire. During this time, like other Great Powers, the UK was involved in colonial exploitation, including the slave trade, while the passing of the 1807 Slave Trade Act also made the UK the first nation to prohibit trade in slaves.

After the defeat of Napoleon in the Napoleonic Wars, Britain became the principal naval power of the 19th century. At its peak the British Empire controlled large amounts of territory in Asia, Africa, Oceania and America.

In the 19th century the country played an important role in the development of parliamentary democracy, partly through the emergence of a multi-party system. At the end of the Victorian era the United Kingdom lost its industrial leadership, particularly to the German Empire, which surpassed the UK in industrial production and trade in the 1890s, and to the United States. Britain remained an eminent power and its empire expanded to its maximum size by 1921, gaining the League of Nations mandate over former German and Ottoman colonies after World War I.

After the Great War, the world's first large-scale international broadcasting network, the BBC, was created. In 1924 the country's Labour movement, which had been gaining strength since the late 1890s, formed the first Labour government. Britain fought Nazi Germany in World War II, with its Commonwealth allies including Canada, Australia, New Zealand, South Africa and India, later to be joined by further allies such as the United States. Wartime leader Winston Churchill and his peacetime successor Clement Atlee helped create the post-war world as part of the "Big Three". World War II left the United Kingdom financially damaged. Loans taken out during and after World War II from both Canada and the United States were economically costly but, along with post-war Marshall aid, the UK began the road to recovery.

The immediate post-war years saw the establishment of the British Welfare State and one of the world's first and most comprehensive health services, while the demands of a recovering economy brought people from all over the Commonwealth to create a multi-ethnic Britain. Although the new post-war limits of Britain's political role were confirmed by the Suez Crisis of 1956, the international spread of the language meant the continuing impact of its literature and culture, while at the same time from the 1960s its popular culture found influence abroad. Following a period of economic stagnation and industrial strife in the 1970s after a global economic downturn, the 1980s saw the inflow of substantial oil revenues, and the premiership of Margaret Thatcher, under whom there was a marked break with the post-war political and economic consensus. Her supporters credit her with economic success, but her critics blame her for greater social division. From 1997 onward these trends of growth largely continued under the leadership of Tony Blair.

The United Kingdom has been a member of the European Union since 1973. The attitude of the present Labour government towards further integration with this organisation is mixed, with the Conservative Party favouring a return of some powers and competencies to the state, and the Liberal Democrats supportive of current engagement.
