Britain is often used informally for the country often known as "The United Kingdom of Great Britain and Northern Ireland". This name is often shortened to The United Kingdom or simply U.K. It lies at the top-left edge of Europe, separated from the mainland by the North Sea and the English Channel.

It became part of the English kingdom in 1282, but keeps a separate language and national identity.

Scotland and England were governed by the same rulers after 1603 and united in 1707 to form Great Britain.
Ireland was made a part of the state in 1801, changing the official name to the United Kingdom of Great Britain and Ireland.
