McCarthyism
The Rise of Senator McCarthy
On 9 February 1950, Senator Joseph McCarthy of Wisconsin spoke at a Republican women’s club in Wheeling, West Virginia. He claimed to be holding a list of 205 members of the Communist Party who were “still working and shaping policy in the State Department.” The precise number varied every time he repeated the claim, but the accusation landed at exactly the right moment — Alger Hiss had just been convicted, the Soviet Union had just tested its first atomic bomb, and China had just ‘fallen’ to Communism. McCarthyism had begun.
McCarthy delivered his Wheeling speech in February 1950, claiming to hold a list of Communists working inside the State Department. The number on the list shifted between speeches, but the charge — that traitors occupied the heart of American government — gripped the nation.
Why McCarthy Had Support
McCarthy was not working alone, and his support came from varied sources. Republican politicians who had spent nearly 20 years out of presidential power saw anti-Communism as a way to attack the Democrats. Business conservatives resented the New Deal and portrayed government regulation as a step towards socialism. Many ordinary Americans were genuinely frightened by the external events of 1949–50. Religious groups saw Communism as an atheist threat to Christian America. McCarthy tapped into all of these currents.
His methods were distinctive. He made sweeping accusations without presenting verifiable evidence. When challenged, he would shift his claims. He called critics of his methods Communist sympathisers, making it dangerous to oppose him publicly. The Democratic-controlled Tydings Committee investigated his original charges in 1950 and concluded they were a “fraud and a hoax,” but McCarthy attacked the committee’s chairman and the report made little impact.
McCarthyism’s most lasting damage was economic and social. People named as Communist sympathisers — teachers, writers, civil servants, scientists, academics — lost their jobs, often without any opportunity to challenge the accusations. The blacklist operated in Hollywood, the civil service and universities. People were dismissed not for proven crimes but for past memberships, attendance at meetings, or association with named individuals. Some emigrated to Europe; others committed suicide. The scale of personal destruction was enormous.
Opposition to McCarthy
Not everyone was silent. Edward R. Murrow, the CBS journalist, produced two landmark television programmes in March 1954 on his show See It Now, using McCarthy’s own words and footage to show viewers how he worked — the interruptions, the unsubstantiated claims, the attacks on witnesses’ patriotism. Murrow’s conclusion was pointed: “We must not confuse dissent with disloyalty.” The programmes shifted public opinion significantly.
McCarthy’s downfall came when he turned on the US Army, claiming in early 1954 that it was harbouring Communists. The Army fought back. Televised hearings ran from April to June 1954. Joseph Welch, the Army’s lead counsel, delivered the most memorable line of the era. When McCarthy attacked a young lawyer in Welch’s firm, Welch said quietly: “Have you no sense of decency, sir, at long last? Have you left no sense of decency?” The hearing room applauded. Millions watching on television saw McCarthy for what he was. In December 1954 the Senate voted 67–22 to censure him for conduct unbecoming a senator. His power evaporated. He died in May 1957.
Two figures broke McCarthy’s hold: journalist Edward R. Murrow, whose televised ‘See It Now’ programmes exposed McCarthy’s methods in March 1954; and Army counsel Joseph Welch, whose “Have you no sense of decency?” rebuke at the Army-McCarthy hearings ended McCarthy’s public support.
McCarthyism and Broader Anti-Communism
It is important to understand that McCarthyism was extreme even within its era. Mainstream anti-Communism — supporting Truman’s Loyalty Order, backing NATO, opposing Soviet expansion — had wide bipartisan support and was a reasonable response to genuine Soviet threats. McCarthyism went further: it used unsubstantiated accusation, bypassed due process and used fear to silence legitimate dissent. The distinction matters for understanding why McCarthy eventually lost support: most Americans could be anti-Communist without endorsing witch-hunts.
The Legacy of McCarthyism
Even after McCarthy’s fall, the damage he had done to American political culture persisted for years. The blacklist in Hollywood continued into the early 1960s. Federal loyalty boards kept operating. People remained reluctant to join organisations or express unorthodox views for fear of being denounced. Some historians argue that McCarthyism permanently narrowed the range of acceptable political speech in America, making it harder to advocate progressive causes without being labelled subversive. Others point out that the institutions ultimately functioned as intended: the Senate censured McCarthy, the free press exposed him, and the courts gradually rolled back the most extreme measures. The debate about the scale of McCarthyism’s long-term damage to American civil liberties remains an active area of historical inquiry.
