Stemming from military practices and a long tradition of teaching by equestrians such as La Guérinière and François Baucher, traditional French equestrianism is essentially represented at the Cadre Noir de Saumur. The practice of equestrianism has evolved towards sport and leisure, opening up to the general public. At the end of the 20th century, the sport became much more democratic, with a sharp rise in the number of riders, particularly young people and women. The teaching of equestrianism as a leisure sport in France is based on the existence of over 8,000 riding schools, which make trained horses available to the public. Their establishment is supported by the French government thanks to a reduced VAT rate from 2004 to 2013. At the end of 2013, riders and industry professionals protested against the increase in VAT on their activity.

A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or imagined, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the medieval Latin Mappa mundi, wherein mappa meant napkin or cloth and mundi the world. Thus, "map" became the shortened term referring to a two-dimensional representation of the surface of the world.

Postal history is the study of postal systems and how they operate and, or, the study of the use of postage stamps and covers and associated postal artifacts illustrating historical episodes in the development of postal systems. The term is attributed to Robson Lowe, a professional philatelist, stamp dealer and stamp auctioneer, who made the first organised study of the subject in the 1930s and described philatelists as "students of science", but postal historians as "students of humanity". More precisely, philatelists describe postal history as the study of rates, routes, markings, and means (of transport).
