Many countries were concerned with the spread of communism after the end of World War II. Which organization was created in 1949 when the United States, Canada, and many western European nations agreed to form a military alliance for defense against the Soviet Union and its allies?

North Atlantic Treaty Organization (NATO), military alliance established by the North Atlantic Treaty (also called the Washington Treaty) of April 4, 1949, which sought to create a counterweight to Soviet armies stationed in central and eastern Europe after World War II.

Hope this helps!
