The word "capitalism" first appeared in the Encyclopedia of France in 1753, and it was used to refer to "a country with rich people". In 1850, Louis Blanc was used to mean that "some people use capital to exclude others", and in 186 1, proudhon defined "capitalism" as "in society". Modern Capitalism published by W Sambat in 1902 formally brought capitalism into the field of academic research. The word "capitalism" was not included in the dictionary of political science published in France until World War I, in the Encyclopedia Britannica until 1926 and in the French academic dictionary until 1936.
