The Second World is a term originating during the Cold War for the industrial socialist states that were under the influence of the Soviet Union. In the first two decades following World War II, 19 communist states emerged; all of these were at least originally within the Soviet sphere of influence, though some (notably Yugoslavia and China) broke with Moscow and developed their own path of socialism while retaining Communist governments. Most communist states remained part of this bloc until the dissolution of the Soviet Union in 1991; afterwards, only five communist states remained: China, Cuba, Laos, North Korea, and Vietnam. Along with "First World" and "Third World", the term was used to divide the states of Earth into three broad categories.
