Descripción:

This was a bill that would haven taken place during the Mexican-American War. If it were to have been passed it would have made it illegal to have slavery in territory the U.S. took as a result of war. This event contributed to the Civil War, because it would have caused a lot of controversy on the balance between the slave and free states.
