East and West.

In the period immediately after the Second World War, many developing nations chose to support the foreign policy preferences of the powerful countries who were giving them aid or credits. This resulted in the division of countries of the world into two clear camps East and West. One was under the influence of the United States and its western allies (west block) and the other was under the influence of the then Soviet Union (east block).
