Membership in France's labour unions accounts for less than 10% of the private sector workforce (in 2003, 8.2% of the workforce) and is concentrated in the education, manufacturing, transportation, and heavy industry sectors. Most unions are affiliated with one of the competing national federations, the largest and most powerful of which are the CGT, FO, and CFDT.
Starting with the 19th century, the historical evolution of the population in France has been extremely atypical in the Western World. Unlike the rest of Europe, France did not experience a strong population growth in the 19th century and first half of the 20th century. Conversely, it experienced a much stronger growth in the second half of the 20th century than the rest of Europe or indeed its own growth in the previous centuries.
Under the constitution, the president was originally elected for a seven year term; this has been reduced to five years. The president names the prime minister, presides over the cabinet, commands the armed forces, and concludes treaties. The president may submit questions to national referenda and can dissolve the National Assembly. In certain emergencies, the president may assume special, comprehensive powers.
France is a founding member of the European Union, and its largest member state with respect to land area. France is also a founding member of NATO and the UN, and a permanent member of the UN Security Council. It is one of only seven acknowledged nuclear powers in existence.
During the latter years of the elderly Charlemagne's rule, the Vikings made advances along the northern and western perimeters of his kingdom. After Charlemagne's death in 814 his heirs were incapable of maintaining any kind of political unity and the once great Empire began to crumble. Viking advances were allowed to escalate, their dreaded longboats sailing up the Loire and Seine Rivers and other inland waterways, wreaking havoc and spreading terror. In 843 the Viking invaders murdered the Bishop of Nantes and a few years after that, they burned the Church of Saint-Martin at Tours. Emboldened by their successes, in 845 the Vikings ransacked Paris. Charles the Simple (898-922), whose territory comprised much of the France of today, was forced during his reign to concede to the Vikings a large area on either side of the Seine River, downstream from Paris, that was to become Normandy.
During the reign of Louis XIV (1643-1715), France was the dominant power in Europe, aided by the diplomacy of Richelieu's successor (1642-1661) Cardinal Mazarin and the economic policies (1661-1683) of Colbert. Renewed war (1667-1668 and 1672-1678) brought further territorial gains (Artois and western Flanders and the free county of Burgundy, left to the Empire in 1482), but at the cost of the increasingly concerted opposition of rival powers.
As France is the most popular touristic country in the world, tourism is a significant contributor to the French Economy. In the 1960s the government heavily promoted the development of skiing in the French Alps through the development of new high level resorts including some of the World's most extensive.
A growing urban-based Protestant minority (later dubbed Huguenots) faced ever harsher repression under the rule of King Henri II. Renewed Catholic reaction headed by the powerful dukes of Guise culminated in a massacre of Huguenots (1562), starting the first of the French Wars of Religion, during which English, (Scottish?), German and Spanish forces intervened on the side of rival Protestant and Catholic forces.
The capital and most populous city, Paris, is one of the most famous and beautiful cities in the world, and home to numerous historical buildings and monuments.
While the main territory of France (la métropole) is located in Western Europe, France is also constituted from territories in North America, the Caribbean, South America, the western and southern Indian Ocean, the northern and southern Pacific Ocean, and Antarctica (sovereignty claims in Antarctica are not recognised by most countries).
