Charles Oscar Paullin, Thirteenth Amendment, January 31, 1865, Vote on Passage of Resolution Submitting (1932)

President Abraham Lincoln understood that the Emancipation Proclamation would need to be followed by a constitutional amendment to solidify the abolition of slavery. In January of 1865, the 13th Amendment passed both houses of Congress, after initially passing the Senate but failing in the House of Representatives the year before. This map, created by Charles Pullin and included in the 1932 Atlas of the Historical Geography of the United States, depicts how House districts voted on the resolution to pass the amendment, with blue representing votes in favor and yellow representing votes against. The 13th Amendment states, “Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."
