The terms First World, Second World, and Third World were originally used to divide the world's nations into three categories. The complete overthrow of the pre–World War II status quo left two superpowers vying for ultimate global supremacy, a struggle known as the Cold War. They created two camps, known as blocs. These blocs formed the basis of the concepts of the First and Second Worlds. The Third World consisted of those countries that were not closely aligned with either bloc.
