third world

During the Cold War, the term Third World referred to the developing countries of Asia, Africa, and Latin America, the nations not aligned with either the First World or the Second World. This usage has become popular, mostly in the western countries, due to the ending of the Cold War.
In the decade following the fall of the Soviet Union and the end of the Cold War in 1991, the term Third World was used interchangeably with developing countries, but the concept has become outdated as it no longer represents the current political or economic state of the world. The three-world model arose during the Cold War to define countries aligned with NATO (the First World), the Eastern Bloc (the Second World, although this term was less used), or neither (the Third World). Strictly speaking, "Third World" was a political, rather than an economic, grouping.
