Series of compromises in 186061 intended to forestall the American Civil War .
Sen. John J. Crittenden proposed constitutional amendments that would reenact provisions of the Missouri Compromise and extend them to the western territories, indemnify owners of fugitive slaves whose return was prevented by antislavery elements in the North, allow a form of popular sovereignty in the territories, and protect slavery in the District of Columbia. The plan was rejected by president-elect Abraham Lincoln and narrowly defeated in the Senate.
