Second World

Former group of states aligned with the Soviet Union

The Second World was one of the "Three Worlds" during the Cold War, which described those countries aligned with the Soviet Union and allies in the Warsaw Pact and Eastern Bloc. This grouping was directly opposed to the First World, which grouped countries aligned with the United States and its allies in NATO and the Western Bloc. The Second World included communist states that were originally under the Soviet sphere of influence, though some eventually broke away from the Soviet ideology (e.g., Yugoslavia's split and China's split) to develop their own path as socialist states while retaining their communist governments.
