Early 1861---A very different 13th Amendment

MARCH 2, 1861:       

 In a last-ditch effort to placate the slaveholding States, the U.S. Congress approves a 13^th Constitutional amendment (“The Corwin Amendment”) that prohibits Congress from abolishing or interfering with slavery as a domestic institution in any State. The amendment is ratified by only two States, Ohio and Maryland, and it never becomes effective.
