McKinley was assassinated early in his second term, shot by Leon Czolgosz on September 6, 1901, and dying of his wounds on September 14. This led to sentiment favoring commemoration of his memory, and the Federal government officially adopted the name Mount McKinley in 1917, when Congress passed and President Woodrow Wilson signed into law "An Act to establish the Mount McKinley National Park in the territory of Alaska" (Public Act No. 353).
