Wilmot Proviso (Amendment to HR 534, 29th Congress), August 8, 1846

Representative David Wilmot proposed the controversial amendment to the appropriations bill ending the Mexican War. Known as the Wilmot Proviso, his amendment would have prohibited slavery in any territory acquired from Mexico. Passed by the House, but not by the Senate—where southern opposition was stronger—the proviso intensified the sectionalism that precipitated the Civil War.
