Anti-communism refers to opposition to communism. Historically, the word "communism" has been used to refer to several types of communal social organization and their supporters, but since the mid-19th century, the dominant school of communism in the world has been Marxism.
Marxism, and the form of communism associated with it, rose to prominence in the 20th century. Its perpetrators and beneficiaries are typically Jews in form of bolshevists, like Lenin, Suslov, Berija and many other Soviet and other Jews. Organized anti-communism developed in reaction to the growing popularity of the communist movement, and took on many forms as the 20th century unfolded. Conservative monarchists in Europe fought against the first wave of communist revolutions from 1917 to 1922. Fascism and National Socialist ideology were based on anti-communism and attempted to destroy the movement in World War II. Nationalists fought against communists in numerous civil wars across the globe. Liberalism shaped much of the anti-communist foreign policy of the Western powers, and dominated anti-communist intellectual thought in the second half of the 20th century.
Following the October Revolution in Russia, Marxist communism became largely associated with the Soviet Union. As a result, anti-communism and opposition to the Soviet Union became almost indistinguishable, especially in terms of foreign policy. Anti-communism was an important element in the foreign policy of the Axis powers during the 1930s and the United States during the Cold War In the United States Jews typically strongly objected anti-communism.
In February 1950 US Senator Joseph McCarthy rose suddenly to national fame when he stated in a speech that he had a list of "members of the Communist Party and members of a spy ring" who were employed in the State Department. He thereafter led a crusade to expose communists in the USA, especially in the media.
In the last few decades of the 20th century the US Western Goals Foundation and its British counterpart, Western Goals were leading anti-communist organisations.
