In 1952, the French
demographer Alfred Sauvy coined the term Third World in reference to the three estates in pre-revolutionary France.
[16] The first two estates being the nobility and clergy and everybody else comprising the third estate.
[16] He compared the
capitalist world (i.e. First World) to the nobility and the
communist world (i.e. Second World) to the clergy. Just as the third estate comprised everybody else, Sauvy called the Third World all the countries that were not in this Cold War division, i.e. the unaligned and uninvolved states in the "East-West Conflict."
[16][17] With the coining of the term Third World directly, the first two groups came to be known as the "First World" and "Second World," respectively. Here the three world system emerged.
