The Domino Theory was the political theory that if one nation fell to communist control then neighboring nations would also fall to communism.

This theory took a prominent significance between the 1950s and 1980s in the United States, during the peak period of Cold War. The theory was used by several US administrations to justify American intervention in the conflict with Soviet Union. The first US president to describe this theory was Dwight D. Eisenhower on April 7, 1954, when he referred to the spreading of communism in Indochina.
