What was the Truman doctrine?

The Truman Doctrine (1947) was designed to support anti-communists and resist the spread of communism. Initially, it stated that the United States would support both Turkey and Greece with economic and military aid, preventing them falling into the Soviet sphere.

It offered support to all countries that declined communism, attempting to contain it, and ultimately end it. The Truman Doctrine also included Marshall Aid, which was money that was offered to all European countries for rebuilding. The Soviet-controlled countries of the Warsaw Pact had to decline this "capitalist" money.

In an address to Congress, President Truman said, "I believe that it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressure.

The Truman Doctrine is the common name for the Cold War strategy of containment versus the Soviet Union and the expansion of communism. This doctrine was first promulgated by President Harry Truman in an address to the U.S. Congress on February 27, 1947.
