Robert Young Hayne (November 10, 1791 – September 24, 1839) was an American politician. He served in the United States Senate from 1823 to 1832, as Governor of South Carolina 1832–1834, and as Mayor of Charleston 1836–1837.^[1] As Senator and Governor, he was a leading figure in the Nullification Crisis and, along with John C. Calhoun and James Hamilton Jr., a vocal proponent of the doctrines of states' rights, compact theory, and nullification; his 1830 debate in the Senate with Daniel Webster is considered a defining episode in the constitutional crisis which precipitated the American Civil War.
