France, officially the French Republic, is a country located in Western Europe, with several overseas islands and territories located on other continents. Metropolitan France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. It is often referred to as L’Hexagone ("The Hexagon") because of the geometric shape of its territory. France is a unitary semi-presidential republic with its main ideals expressed in the Declaration of the Rights of Man and of the Citizen.
Metropolitan France is bordered (clockwise from the north) by Belgium, Luxembourg, Germany, Switzerland, Italy, Monaco, Andorra, and Spain. France's overseas departments and collectivities also share land borders with Brazil and Suriname (bordering French Guiana), and the Netherlands Antilles (bordering Saint-Martin). France is linked to the United Kingdom by the Channel Tunnel, which passes underneath the English Channel.
France is the largest country in the European Union and the second largest in Europe behind Ukraine (first if we include its extra-European territories (like Guadeloupe) to the Metropole). France has been a major power for many centuries with strong economic, cultural, military and political influence. During the 17th and 18th centuries, France colonized much of North America; during the 19th and early 20th centuries, France built the second largest empire of the time, including large portions of North, West and Central Africa, Southeast Asia, and many Pacific islands. France is a developed country and possesses the fifth largest economy by nominal GDP and eighth largest economy by purchasing power parity. It is the most visited country in the world, receiving 82 million foreign tourists annually. France is one of the founding members of the European Union, and has the largest land area of all members. It is also a founding member of the United Nations, and a member of the Francophonie, the G8, NATO, OECD, WTO and the Latin Union. It is one of the five permanent members of the United Nations Security Council, possesses the third largest number of nuclear weapons in the world and the largest number of nuclear power plants in the European Union.
