Benjamin Harrison was the 23rd President of the United States (1889–1893). Harrison, a grandson of President William Henry Harrison, was born in Ohio, and moved to Indianapolis, Indiana, at age 21, eventually becoming a prominent politician there. During the American Civil War, he served the Union as a Brigadier General in the XX Corps of the Army of the Cumberland. After the war he unsuccessfully ran for the governorship of Indiana and was later elected to the U.S. Senate by the Indiana legislature.
Harrison, a Republican, was elected to the presidency in 1888, defeating Democrat incumbent Grover Cleveland. He is to date the only U.S. president from Indiana and the only one to be the grandson of another president. He was also the great-grandson of Benjamin Harrison V, a founding father. Before ascending to the presidency, Harrison established himself as a prominent local attorney, Presbyterian church leader, and politician in Indianapolis, Indiana. During the American Civil War, he served in the Union Army as a colonel, and was confirmed by the U.S. Senate as a brevet brigadier general of volunteers in 1865. Harrison unsuccessfully ran for governor of Indiana in 1876. The Indiana General Assembly elected Harrison to a six-year term in the U.S. Senate, where he served from 1881 to 1887.
