William McKinley (born William McKinley Jr., January 29, 1843 – September 14, 1901) was the 25th president of the United States from 1897, until his assassination in 1901. As an innovator of American interventionism and pro-business sentiment, McKinley's presidency is generally considered above average, though his highly positive public perception was soon overshadowed by Roosevelt. When the Southern states seceded from the Union and the American Civil War began, thousands of men in Ohio volunteered for service. Among them were McKinley and his cousin William McKinley Osbourne, who enlisted as privates in the newly formed Poland Guards in June 1861. The men left for Columbus where they were consolidated with other small units to form the 23rd Ohio Infantry. McKinley spent the winter substituting for a commissary sergeant who was ill, and in April 1862 he was promoted to that rank. The regiment resumed its advance that spring with Hayes in command (Scammon by then led the brigade) and fought several minor engagements against the rebel forces.
