The Bricker Amendment is the collective name of a number of proposed amendments to the United States Constitution considered by the United States Senate in the 1950s. Each of these amendments would have placed restrictions on the scope and ratification of treaties and executive agreements entered into by the United States and are named for their sponsor, Republican Senator John W. Bricker of Ohio.
Non-interventionism, the view that the United States should not become embroiled in foreign conflicts and world politics, has always been an element in American politics but was especially strong in the years following World War I. American entry into World War II temporarily suppressed non-interventionist sentiments, but they returned in the post-war years in response to America's new international role, particularly as a reaction to the new United Nations and its affiliated international organizations. Some feared the loss of American sovereignty to these transnational agencies, because of the Soviet Union's role in the spread of international Communism and the Cold War.
Frank E. Holman, president of the American Bar Association (ABA), called attention to state and Federal court decisions, notably Missouri v. Holland, which he claimed could give international treaties and agreements precedence over the United States Constitution and could be used by foreigners to threaten American liberties. Senator Bricker was influenced by the ABA's work and first introduced a constitutional amendment in 1951. With substantial popular support and the election of a Republican President and Congress in the elections of 1952, Bricker's plan seemed destined to be sent to the individual states for ratification.
