Benjamin Harrison was an American politician and lawyer who served as the 23rd president of the United States from 1889 to 1893. He was a grandson of the ninth president, William Henry Harrison, creating the only grandfather–grandson duo to have held the office. 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.
