César-François Cassini de Thury (born June 17, 1714, Thury, France—died Sept. 4, 1784, Paris) was a French astronomer and geodesist, who continued surveying work undertaken by his father, Jacques Cassini, and began construction of a great topographical map of France.
Although he, his father, and his grandfather had defended the Cartesian view that the Earth is somewhat elongated (with a polar diameter greater than the equatorial diameter), Cassini III abandoned that position in the face of growing evidence that favoured the opposite, so-called Newtonian view that the Earth is flattened at the poles. He succeeded his father as director of the Paris Observatory in 1771, but his achievements as an astronomer were less distinguished then those as a geodesist and cartographer. From the 1740s until his death, Cassini de Thury directed work on a general topographic map of France. Published in 1789, this Carte géométrique de la France (“Geometric Map of France”), or Carte de Cassini, was the first map of an entire country drawn up on the basis of extensive triangulation and topographic surveys. Another of his works is Description géométrique de la Terre (1775; “Geometric Description of the Earth”).

France, country of northwestern Europe. Historically and culturally among the most important nations in the Western world, France has also played a highly significant role in international affairs, with former colonies in every corner of the globe. Bounded by the Atlantic Ocean and the Mediterranean Sea, the Alps and the Pyrenees, France has long provided a geographic, economic, and linguistic bridge joining northern and southern Europe. It is Europe’s most important agricultural producer and one of the world’s leading industrial powers.
France is among the globe’s oldest nations, the product of an alliance of duchies and principalities under a single ruler in the Middle Ages. Today, as in that era, central authority is vested in the state, even though a measure of autonomy has been granted to the country’s régions in recent decades. The French people look to the state as the primary guardian of liberty, and the state in turn provides a generous program of amenities for its citizens, from free education to health care and pension plans. Even so, this centralist tendency is often at odds with another long-standing theme of the French nation: the insistence on the supremacy of the individual. On this matter historian Jules Michelet remarked, “England is an empire, Germany is a nation, a race, France is a person.” Statesman Charles de Gaulle, too, famously complained, “Only peril can bring the French together. One can’t impose unity out of the blue on a country that has 265 kinds of cheese.”
This tendency toward individualism joins with a pluralist outlook and a great interest in the larger world. Even though its imperialist stage was driven by the impulse to civilize that world according to French standards (la mission civilisatrice), the French still note approvingly the words of writer Gustave Flaubert:
I am no more modern than I am ancient, no more French than Chinese; and the idea of la patrie, the fatherland—that is, the obligation to live on a bit of earth coloured red or blue on a map, and to detest the other bits coloured green or black—has always seemed to me narrow, restricted, and ferociously stupid.
At once universal and particular, French culture has spread far and greatly influenced the development of art and science, particularly anthropology, philosophy, and sociology.
France has also been influential in government and civil affairs, giving the world important democratic ideals in the age of the Enlightenment and the French Revolution and inspiring the growth of reformist and even revolutionary movements for generations. The present Fifth Republic has, however, enjoyed notable stability since its promulgation on September 28, 1958, marked by a tremendous growth in private initiative and the rise of centrist politics. Although France has engaged in long-running disputes with other European powers (and, from time to time, with the United States, its longtime ally), it emerged as a leading member in the European Union (EU) and its predecessors. From 1966 to 1995 France did not participate in the integrated military structure of the North Atlantic Treaty Organization (NATO), retaining full control over its own air, ground, and naval forces; beginning in 1995, however, France was represented on the NATO Military Committee, and in 2009 French President Nicolas Sarkozy announced that the country would rejoin the organization’s military command. As one of the five permanent members of the United Nations Security Council—together with the United States, Russia, the United Kingdom, and China—France has the right to veto decisions put to the council.
The capital and by far the most important city of France is Paris, one of the world’s preeminent cultural and commercial centres. A majestic city known as the ville lumière, or “city of light,” Paris has often been remade, most famously in the mid-19th century under the command of Georges-Eugène, Baron Haussman, who was committed to Napoleon III’s vision of a modern city free of the choleric swamps and congested alleys of old, with broad avenues and a regular plan. Paris is now a sprawling metropolis, one of Europe’s largest conurbations, but its historic heart can still be traversed in an evening’s walk. Confident that their city stood at the very centre of the world, Parisians were once given to referring to their country as having two parts, Paris and le désert, the wasteland beyond it. Metropolitan Paris has now extended far beyond its ancient suburbs into the countryside, however, and nearly every French town and village now numbers a retiree or two driven from the city by the high cost of living, so that, in a sense, Paris has come to embrace the desert and the desert Paris.
