AMSCO 8.3 The Red Scare

Overview

AMSCO Topic 8.3, The Red Scare, covers the second Red Scare that swept the United States after World War II, when fear of Communist spies and subversion reshaped politics, government, and culture. The chapter explains how loyalty programs, congressional investigations, real espionage cases, and Senator Joseph McCarthy's accusations made anticommunism a defining feature of Period 8 (1945-1980). The big tension you need to track: both parties agreed on containing communism abroad, but Americans fiercely debated the methods used to root out suspected Communists at home, and whether those methods trampled civil liberties.

This topic connects directly to AMSCO 8.2, the Cold War from 1945 to 1980. The foreign-policy fear of Soviet expansion is what fueled the domestic fear of infiltration. Just as a Red Scare followed the U.S. victory in World War I, a second one followed victory in World War II.

Rooting Out Communists: Government Anticommunism

The Truman administration tended to see a Communist conspiracy behind civil wars in Europe and Asia, and that mindset fed the belief that Communist spies had infiltrated American society, including the State Department and the U.S. military. The government responded with loyalty checks, prosecutions, and new laws.

The Loyalty Review Board (1947-1951)

• In 1947, under pressure from Republican critics, the Truman administration set up a Loyalty Review Board to investigate the backgrounds of more than 3 million federal employees.
• The probe ran for four years (1947-1951). Thousands of officials and civil service employees resigned or lost their jobs.
• Notice the politics here: a Democratic president created this program partly to deflect Republican accusations of being "soft" on communism.

The Smith Act and Dennis v. United States

• The Smith Act (1940) made it illegal to advocate or teach the overthrow of the U.S. government by force, or to belong to an organization with that goal.
• Leaders of the American Communist Party were jailed under it.
• In Dennis et al. v. United States (1951), the Supreme Court upheld the Smith Act as constitutional. This mattered because it put the Court's stamp of approval on prosecuting people for political advocacy, not just actions.

McCarran Internal Security Act (1950)

Congress passed this law over Truman's veto, which tells you how strong anticommunist pressure was. It did three things:

1. Made it unlawful to advocate or support the establishment of a totalitarian government
2. Restricted the employment and travel of people who joined Communist-front organizations
3. Authorized the creation of detention camps for subversives

HUAC and the Hollywood Blacklist

• The House Un-American Activities Committee (HUAC) was originally created in 1939 to seek out Nazis. After the war, it was reactivated to hunt for Communists.
• HUAC investigated government officials but also looked for Communist influence in groups like the Boy Scouts and, most famously, the Hollywood film industry.
• Actors, directors, and writers were called to testify. Those who refused were tried for contempt of Congress. Others were blacklisted, meaning no studio would hire them.

Cultural Impact and Pushback

The Red Scare had a chilling effect on free expression, and artists fought back in creative ways:

• Loyalty oaths became a common condition of employment for writers and teachers.
• Creators of film noir crime dramas and playwrights like Arthur Miller (Death of a Salesman, 1949) were attacked as anti-American. Rodgers and Hammerstein's South Pacific (1949) was criticized, especially by Southern politicians, as a "Communistic" assault on racial segregation.
• The American Civil Liberties Union argued the First Amendment protected unpopular political views and membership in political groups, including the Communist Party.
• Shirley Jackson's "The Lottery" (1948) depicted a town blindly following a deadly tradition, a clear comment on conformity.
• Playwright Lillian Hellman refused to testify before HUAC in 1952, saying, "I cannot and will not cut my conscience to fit this year's fashions." She was blacklisted.
• Arthur Miller's The Crucible (1953), about the Salem witch trials, was a thinly veiled metaphor for the persecution of suspected Communists. If an APUSH question pairs the Salem witch trials with the 1950s, this is the connection it wants.

Espionage Cases: Real Spies, Real Fears

The fear of a Communist conspiracy wasn't pure paranoia. Actual espionage cases in Great Britain, Canada, and the United States gave it credibility. But the methods used to identify spies raised serious questions about whether the government was going too far and violating civil liberties.

The Hiss Case

• Whittaker Chambers, himself a Communist, was a star witness for HUAC in 1948. His testimony, plus the investigative work of a young California congressman named Richard Nixon, led to the trial of Alger Hiss.
• Hiss was a prominent State Department official who had assisted Roosevelt at the Yalta Conference. He denied being a Communist and denied giving secret documents to Chambers.
• In 1950, Hiss was convicted of perjury and sent to prison.
• The takeaway for many Americans: if someone that high up could be a spy, maybe the highest levels of government really were infiltrated.

The Rosenberg Case

• When the Soviets tested their first atomic bomb in 1949, many Americans concluded that spies had stolen the technology from the United States.
• Klaus Fuchs, a British scientist on the Manhattan Project, admitted giving A-bomb secrets to the Russians.
• An FBI investigation traced another spy ring to Julius and Ethel Rosenberg in New York. After a controversial trial in 1951, they were found guilty of treason and executed in 1953.
• Civil rights groups charged that anti-Communist hysteria, not solid evidence, drove the conviction and execution. The case became a symbol of the Red Scare's excesses.

The Rise and Fall of Joseph McCarthy

Joseph McCarthy, a Republican senator from Wisconsin, used the growing fear of communism to build his political career, and "McCarthyism" became the label for his whole style of reckless accusation.

McCarthy's Rise and Tactics

• In a 1950 speech, McCarthy claimed to have a list of 205 Communists working in the State Department. In other speeches, the number kept changing.
• The press publicized the sensational, unproven accusation, and McCarthy became one of the most powerful figures in America. Other politicians feared what would happen if he pointed his accusing finger at them.
• He used a steady stream of unsupported accusations to keep media attention on himself and to discredit the Truman administration.
• Working-class Americans initially loved his hard-hitting, "take the gloves off" attacks, often aimed at the wealthy and privileged.
• Many Republicans disliked his ruthless tactics but tolerated him because he was mainly hurting Democrats before Eisenhower's election in 1952. McCarthy grew so popular that even Eisenhower would not defend his old friend George Marshall against McCarthy's untruths.

The Army-McCarthy Hearings and Censure (1954)

• In 1954, a Senate committee held televised hearings on alleged Communist infiltration in the army. Television exposed McCarthy's "reckless cruelty," and millions of viewers saw him as a bully.
• In December 1954, Republicans joined Democrats in a Senate censure of McCarthy. The "witch hunt" had played itself out.
• McCarthy died three years later, a broken man.

Why the Red Scare Faded

• It became clear that fear of a Communist takeover of the United States was overblown.
• Cooler heads, including President Eisenhower, took control of the political dialogue.
• After the Korean War armistice, average Americans pushed fears of communism into the background and focused on the booming 1950s economy (covered in AMSCO 8.4, Economy after 1945).
• AMSCO's closing warning: the language, tactics, and threats of McCarthyism remained a danger to democracy whenever politics turned bitter and partisan.
