Passage: French demographer, anthropologist and historian Alfred Sauvy, in an article published in the French magazine L'Observateur, August 14, 1952, coined the term Third World (French: Tiers Monde), 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. Sauvy wrote, "This third world ignored, exploited, despised like the third estate also wants to be something." He conveyed the concept of political non-alignment with either the capitalist or communist bloc.
