The vertical country of the second world. by Sergey Prokofyev
The term of classification of the world division into first, second and third appeared in the middle of the 20th century during the cold war. The countries of the first world were the democratic countries of the Northern Alliance. The countries of the second world were the countries of the Warsaw Agreement and the USSR, as well as the communist countries. The countries of the third world are the countries which failed to participate in the cold war directly, but still were the arena of rivalry. This classification was of political nature.
