Anarchist Shoots President McKinley at Exposition
William McKinley, the 25th U.S. president, had led the nation through the Spanish-American War and was serving his second term amid growing industrial prosperity. On September 6, 1901, while greeting the public at the Temple of Music during the Pan-American Exposition in Buffalo, New York, he was approached by Leon Czolgosz, a 28-year-old unemployed anarchist. Czolgosz fired two shots from a revolver concealed under a handkerchief, striking McKinley in the abdomen. The president initially appeared stable after emergency surgery but succumbed to gangrene on September 14, becoming the third U.S. president assassinated in 36 years. Czolgosz was quickly tried, convicted, and executed later that year.
Why it matters: The assassination prompted heightened security measures for presidents and accelerated the rise of Vice President Theodore Roosevelt, whose progressive policies reshaped American politics and foreign affairs in the early twentieth century.
