France has 26 régions: 21 of these are in the continental part of metropolitan France, one is Corse on the island of Corsica (although strictly speaking Corse is in fact a "territorial collectivity", not a région, but is referred to as a région in common speech), 4 are overseas. The région are further subdivided into 100 départements.
France's founding membership in the European Union largely defines France's current foreign policy. The French Republic is furthermore a member of the Secretariat of the Pacific Community (SPC) and of the Indian Ocean Commission (COI), and an associate member of the Association of Caribbean States (ACS). France is also a leading member or the International Organisation of Francophonie (OIF) which gathers 51 fully or partly French-speaking countries.
France has a system of civil law, but jurisprudence plays an important role similar to that of case law. France uses a civil law system; that is, law arises primarly from written statutes; judges are supposed not to make law, but to merely interpret it (though the amount of judge interpretation in certain areas makes it equivalent to case law). Many fundamental principles of French Law were laid in the Napoleonic Codes. Basic principles of the rule of law were laid in the Napoleonic Code: laws can only address the future and not the past (ex post facto laws are prohibited); to be applicable, laws must have been officially published (see Journal Officiel).
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.
Louis XVI's reign (1774-1792) saw a temporary revival of French fortunes through intervention (1778-1783) in support of Britain's rebel American colonies. But the over-ambitious projects and military campaigns the past century had produced chronic financial problems. Deteriorating economic conditions, popular resentment against the complicated system of privileges granted the nobility and clerics, and a lack of alternate avenues for change were among the principal causes of the French Revolution. This led to the formation of the First Republic on September 21, 1792.
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).
A popular referendum approved the constitution of the French Fifth Republic in 1958, greatly strengthening the authority of the presidency and the executive in relation to Parliament. The French constitution establishes a semi-presidential system, where the President of France has a strong influence, but where, ultimately, the deciding factor is the majority of the French National Assembly.
Senators are chosen by an electoral college of about 145,000 local elected officials for 6-year terms, and one half of the Senate is renewed every 3 years. Before the law of 30 July 2004, senators were elected for 9 years, renewed by thirds every 3 years. There are currently 321 senators, but there will be 346 in 2010; 304 represent the metropolitan and overseas départements, five the other dependencies and 12 the French established abroad.
In 1959, in an occasion marking the first time in the 20th century that the people of France went to the polls to elect a president by direct ballot, de Gaulle won re-election with a 55% share of the vote, defeating François Mitterrand.
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.
France is a unitary state. However, the various legal subdivisions, the régions, départements and communes, have various attributions, and the national government is prohibited from intruding into their legal normal operations.
