where did the terms first - third world come from who did they refer to at the time
Third World The term "Third World" arose during the Cold War to define countries that remained non-aligned with either NATO or the Communist Bloc. The United States, Canada, Japan, South Korea, Western European nations and their allies represented the First World, while the Soviet Union, China, Cuba, and their allies represented the Second World. This terminology provided a way of broadly categorizing the nations of the Earth into three groups based on political and economic divisions. Since the fall of the Soviet Union and the end of the Cold War, the term Third World has been used less and less. It is being replaced with terms such as developing countries, least developed countries or the Global South. The concept itself has become outdated as it no longer represents the current political or economic state of the world.
Globalization Though many scholars place the origins of globalization in modern times, others trace its history long before the European Age of Discovery and voyages to the New World, some even to the third millennium BC.[6][7] Large-scale globalization began in the 1820s.[8] In the late 19th century and early 20th century, the connectivity of the world's economies and cultures grew very quickly. The term globalization is recent, only establishing its current meaning in the 1970s.[9]
