France, officially the French Republic (République française, ), is a country whose territory consists of metropolitan France in Western Europe and several overseas regions and territories. The metropolitan area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. It is bordered by Belgium, Luxembourg and Germany to the northeast, Switzerland and Italy to the east, and Andorra and Spain to the south. The overseas territories include French Guiana in South America and several islands in the Atlantic, Pacific and Indian oceans. The country's 18 integral regions (five of which are situated overseas) span a combined area of 643801 km2 and a total population of 67.3 million . France, a sovereign state, is a unitary semi-presidential republic with its capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban areas include Lyon, Marseille, Toulouse, Bordeaux, Lille and Nice.
During the Iron Age, what is now metropolitan France was inhabited by the Gauls, a Celtic people. Rome annexed the area in 51 BC, holding it until the arrival of Germanic Franks in 476, who formed the Kingdom of Francia. The Treaty of Verdun of 843 partitioned Francia into East Francia, Middle Francia and West Francia. West Francia which became the Kingdom of France in 987 emerged as a major European power in the Late Middle Ages following its victory in the Hundred Years' War (1337–1453). During the Renaissance, French culture flourished and a global colonial empire was established, which by the 20th century would become the second largest in the world. The 16th century was dominated by religious civil wars between Catholics and Protestants (Huguenots). France became Europe's dominant cultural, political, and military power in the 17th century under Louis XIV. In the late 18th century, the French Revolution overthrew the absolute monarchy, established one of modern history's earliest republics, and saw the drafting of the Declaration of the Rights of Man and of the Citizen, which expresses the nation's ideals to this day.
