United Kingdom.

Established in 1801, the United Kingdom of Great Britain and Northern Ireland is made up of the countries of England, Wales, Scotland, and Northern Ireland. The United Kingdom (UK) is located on the islands of Great Britain and Ireland in Western Europe. The United Kingdom joined the European Union (EU) in 1973. However, in 2016, UK citizens narrowly voted for the country to leave the EU. The UK’s official exit from the EU, or “Brexit,” occurred in January 2020, but negotiations over trade and immigration continued.
