French demographer, anthropologist and historian Alfred Sauvy, in an article published in the French magazine L'Observateur in August 14, 1952, coined the term Third World, referring to countries that were unaligned with either the Communist Soviet bloc or the Capitalist NATO bloc during the Cold War. His usage was a reference to the Third Estate, the commoners of France who, before and during the French Revolution, opposed the clergy and nobles, who composed the First Estate and Second Estate, respectively.
