The Rise and Fall of McCarthyism

President Harry Truman provided the institutional framework for screening federal employees by issuing Executive Order 9835 in 1947, which established the FELP. Supported by FBI Director J. Edgar Hoover, who compiled extensive files on suspects, these Loyalty Boards investigated 3 million government employees by 1951. Rather than looking for concrete evidence of espionage, they targeted individuals deemed subversive. By 1954, approximately 6.6 million workers had been screened, resulting in 9,500 dismissals and 15,000 resignations from individuals desperate to avoid investigation.

The Hollywood Ten and High-Profile Espionage

Imagine losing your career and facing prison simply because you refused to answer a question about your political beliefs. This was the reality for the Hollywood Ten in 1947. HUAC subpoenaed 41 writers, directors, and producers, asking them to declare their political affiliations. Ten of these individuals, including Dalton Trumbo, cited their First Amendment rights and refused to answer. They were convicted of contempt of Congress, fined $1,000 each, and sentenced to a year in prison.

This led to widespread blacklisting across the entertainment industry. Following the publication of right-wing pamphlets like Red Channels (which named 151 professionals), over 300 individuals lost their livelihoods because studios refused to hire anyone suspected of communist sympathies. Public fear was further validated by major espionage trials. The perjury conviction of State Department official Alger Hiss in 1950 and the execution of Julius and Ethel Rosenberg in 1953 for passing atomic secrets to the USSR provided a "smokescreen of credibility" for the hysteria that followed.

The Rise of McCarthy and Reasons for Support

Why did so many Americans believe a relatively unknown senator when he claimed the government was full of traitors? Senator Joseph McCarthy skyrocketed to fame following his Wheeling Speech on 9 February 1950, where he claimed to possess a list of 205 "card-carrying" communists in the State Department. Despite his numbers constantly fluctuating down to 57 and then 81, his claims resonated deeply with a frightened public.

The widespread support for McCarthyism can be evaluated through both social and political lenses:

• Social Paranoia: In 1949, the "Fall of China" to Mao Zedong and the USSR's successful test of an atomic bomb shattered America's sense of security. The outbreak of the Korean War in 1950 further heightened the demand for absolute domestic loyalty.
• Political Strategy: Key Republicans, such as Richard Nixon and Robert Taft, actively supported McCarthy's "Red-baiting" tactics because it provided a powerful weapon to attack Truman's Democratic administration.

Polling data reveals that by June 1950, 61% of Americans expressed some form of approval for McCarthy. Support was demographically concentrated among Republicans (62%) and Catholics (58%).

The Nature of McCarthy's Methods

Instead of relying on solid legal evidence, McCarthy mastered the art of public intimidation. His primary method was "guilt by association"—meaning that simply being acquainted with a suspected communist was enough to ruin a person's reputation. He led a brutal witch hunt, using televised hearings to bully witnesses and exploit public anxiety.

The societal impact was devastating. Approximately 400 people were imprisoned, and roughly 600 teachers and university lecturers were fired. The climate of fear was so intense that ordinary citizens refused to sign everyday petitions for fear of being labeled radicals. Furthermore, McCarthyism severely stalled the Civil Rights movement, as equality activists were frequently smeared as communists to invalidate their cause.

Opposition and the Decline of McCarthyism

Standing up to a powerful bully often carries severe risks, as early opponents of McCarthy quickly discovered. In 1950, the Tydings Committee investigated McCarthy's initial claims and concluded they were a "fraud and a hoax." However, McCarthy aggressively retaliated by using doctored photographs to ruin Senator Millard Tydings' re-election campaign. Terrified by Tydings' defeat, other senators remained silent, while Republicans dismissed the committee's findings as a whitewash.

McCarthy's ultimate downfall was triggered by two major external factors in 1954:

• The Murrow Broadcast: On 9 March 1954, journalist Edward R. Murrow used McCarthy's own words against him on the television programme See It Now. This exposure flipped public opinion; McCarthy's favorable ratings plummeted from 46% to 34% within a month.
• The Army-McCarthy Hearings: Broadcast live over 36 days to a daily audience of 20 million, these hearings exposed McCarthy's cruel, bullying nature. The defining moment came when Army lawyer Joseph N. Welch asked, "Have you no sense of decency, sir, at long last?"

Following the suicide of Senator Lester Hunt—who had been pressured by McCarthy's allies—the US Senate finally took action. On 2 December 1954, they voted 67 to 22 to censure McCarthy, effectively ending his political power.

Evaluating the Significance of the Era

The significance of McCarthyism lies in its profound long-term damage to both American society and foreign policy. Domestically, it created a suffocating culture of conformity that silenced political dissent and weakened trade unions for over a decade. On an international level, the hysteria locked the United States into rigid anti-communist stances. Because no politician could risk appearing "soft on Communism," the US was pushed toward inflexible policies of containment, deepening its future involvement in conflicts like the Vietnam War.
