Schuyler Colfax Jr. was an American journalist, businessman, and politician who served as the 17th vice president of the United States from 1869 to 1873, and prior to that as the 25th speaker of the House of Representatives from 1863 to 1869. Originally a Whig and later a Republican, he was the U.S. Representative for Indiana's 9th congressional district from 1855 to 1869.
Colfax was known for his opposition to slavery while serving in Congress, and was a founder of the Republican Party. During his first term as speaker he led the effort to pass the Thirteenth Amendment to the United States Constitution, which abolished slavery. When it came before the House for a final vote in January 1865, he emphasized his support by casting a vote in favor—by convention the speaker votes only to break a tie. Chosen as Ulysses S. Grant's running mate in the 1868 election, the pair won easily over Democratic Party nominees Horatio Seymour and Francis Preston Blair Jr. As was typical during the 19th century, Colfax had little involvement in the Grant administration. In addition to his duties as president of the U.S. Senate, he continued to lecture and write for the press while in office.
