EXPLANATIONS BELOW
Concept note-1: -Passed by Congress on January 31, 1865, and ratified on December 6, 1865, the 13th Amendment abolished slavery in the United States.
Concept note-2: -With the ratification of the Thirteenth Amendment, four million African Americans-almost a third of the population of the South-became permanently free and slavery was abolished in the United States: Section 1.
Concept note-3: -The Emancipation Proclamation described enslaved people as “all persons held as slaves” and tells them to abstain from all violence (except in self-defense) and to labor for reasonable wages. The 13th Amendment describes ending “slavery or involuntary servitude, except as punishment for a crime."
Concept note-4: -The 13th Amendment was necessary because the Emancipation Proclamation, issued by President Abraham Lincoln in January of 1863, did not end slavery entirely; those ensllaved in border states had not been freed.
