Saint Kitts and Nevis ( (listen)), also known as the Federation of Saint Christopher and Nevis, is an island country in the West Indies. Located in the Leeward Islands chain of the Lesser Antilles, it is the smallest sovereign state in the Western Hemisphere, in both area and population. The country is a Commonwealth realm, with Elizabeth II as queen and head of state.
The British dependency of Anguilla was historically also a part of this union, which was then known collectively as Saint Christopher-Nevis-Anguilla. To the north-northwest lie the islands of Sint Eustatius, and Saba, Saint Barthélemy, Saint-Martin/Sint Maarten and Anguilla. To the east and northeast are Antigua and Barbuda, and to the southeast is the small uninhabited island of Redonda, and the island of Montserrat, which currently has an active volcano (see Soufrière Hills).
Saint Kitts and Nevis were among the first islands in the Caribbean to be settled by Europeans. Saint Kitts was home to the first British and French colonies in the Caribbean, and thus has also been titled "The Mother Colony of the West Indies".
