The United Kingdom of Great Britain and Northern Ireland, commonly referred to as the United Kingdom (UK), is a sovereign state located on the British isles in Western Europe. The nation borders Ireland via Northern Ireland, and shares overseas borders with France, Belgium and the Netherlands to the southeast. The United Kingdom is the 11th-largest country in Europe, and has a population of around 67 million.

The United Kingdom emerged from a series of annexations and unifications, beginning with the unification of England (including Wales, which had been annexed in 1542) and Scotland in 1707, forming the Kingdom of Great Britain. Its union in 1801 with the Kingdom of Ireland created the United Kingdom of Great Britain and Ireland. Throughout the 19th century, Great Britain expanded its colonial empire, becoming the biggest empire in history by 1921 in the aftermath of World War I. In 1922, Ireland gained independence, while the United Kingdom reconstituted itself as the United Kingdom of Great Britain and Northern Ireland.
