6 September – On this day

President William McKinley is shaking hands at the Pan-American Exhibition in Buffalo, New York, when a 28-year-old anarchist named Leon Czolgosz approaches him and fires two shots into his chest.

Czolgosz attempted to fire a third shot, but was wrestled to the ground by McKinley’s bodyguards. Other presidential attendants rushed McKinley to the hospital where they found two bullet wounds: one bullet had superficially punctured his sternum and the other had dangerously entered his abdomen. He was rushed into surgery, but his early good prognosis did not hold, his condition worsened, and on 14 September, McKinley died from gangrene that had gone undetected in the internal wound. Vice President Theodore Roosevelt was immediately sworn in as president.
