The presidency of William McKinley began on March 4, 1897, when William McKinley was inaugurated and ended with his death on September 14, 1901. He is best known for leading the nation to victory in the Spanish–American War (1898), taking ownership of the Republic of Hawaii, purchasing the Philippines, Guam and Puerto Rico. It includes the 1897 Dingley Tariff to protect manufacturers and factory workers from foreign competition, and the Gold Standard Act of 1900 that rejected free silver inflationary proposals. Rapid economic growth and a decline in labor conflict also marked the presidency. 'Well, I hardly know which to take first!' exclaims Uncle Sam in this May 18, 1898, editorial cartoon celebrating the spoils of victory.
