William McKinley was the 25th President of the United States, serving from March 4, 1897, until his assassination on September 14, 1901, after leading the nation to victory in the Spanish-American War and raising protective tariffs to promote American industry.
During the Civil War, McKinley served on the staff of Colonel Rutherford B. Hayes, a fellow Ohioan who would become his lifelong mentor and friend. His ties to Hayes helped McKinley rise through Ohio's political ranks and win election to Congress in 1876, the same year Hayes was elected as the nation's 19th president. McKinley entered Ohio politics in 1869 and rose through the ranks as a Republican, winning election to the U.S. Congress in 1876.
