The 1952 steel strike was a strike by the United Steelworkers of America against U.S. Steel and nine other steelmakers. The strike was scheduled to begin on April 9, 1952, but President Harry S Truman nationalized the American steel industry hours before the workers walked out. The steel companies sued to regain control of their facilities. On June 2, 1952, in a landmark decision, the United States Supreme Court ruled in Youngstown Sheet & Tube Co. v. Sawyer, 343 U.S. 579 (1952), that the president lacked the authority to seize the steel mills. The Steelworkers struck to win a wage increase. The strike lasted 53 days, and ended on July 24, 1952, on essentially the same terms the union had proposed four months earlier.
On February 9, 1950, Senator Joseph McCarthy denounced the administration of President Harry S Truman for permitting known communists to remain in the employment of the United States government. The incident sparked a four-year period of anti-communist policies and attitudes which came to be known as McCarthyism. The accusations by McCarthy and others put the Truman administration on the political defensive, and led President Truman to seek ways in which he might prove he was not "soft on communism."
On June 25, 1950, North Korea invaded South Korea, touching off the Korean War. American wartime mobilization agencies, including the recently formed National Security Resources Board (NSRB), were dormant. President Truman attempted to use the NSRB as the nation's military mobilization agency. The president quadrupled the defense budget to $50 billion, and the NSRB placed controls on prices, wages and raw materials. Inflation soared and shortages in food, consumer goods and housing appeared.
