The United Kingdom of Great Britain and North Ireland (including England, Scotland, Wales and North Ireland) is a constitutional monarchy located off the northwest coast of the European continent. In the 19th century Britain was the world foremost colonial power. By the mid-20th century, most of the territories formerly comprising the British empire had gained independence, and the empire had evolved into the Commonwealth of nations.

The Bank of England notes are used throughout United Kingdom. However, Northern Ireland and Scotland also use banknotes issued by local banks.
