Benjamin Harrison was an American lawyer and politician 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, and a great-grandson of Benjamin Harrison V, a founding father who signed the United States Declaration of Independence.
Harrison was born on a farm by the Ohio River and graduated from Miami University in Oxford, Ohio. After moving to Indianapolis, he established himself as a prominent local attorney, Presbyterian church leader, and politician in 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.
A Republican, Harrison was elected to the presidency in 1888, defeating the Democratic incumbent, Grover Cleveland.
