A constituent country is a type of country which serves as an administrative division. Constituent countries usually form together to make a larger sovereign country. Unlike federal countries, power between constituent countries may not be spread out evenly, with one of them usually holding the capital and government.
The United Kingdom is a sovereign country made of four constituent countries. They are England, Scotland, Wales, and Northern Ireland. While all four are often referred to as countries, they are technically constituent countries within a sovereign country, the UK. They are also sometimes referred to as regions, provinces, nations, or statelets. However, these titles are problematic and in particular, sensitive in Northern Ireland.
