Mississippi Making History
I gathered this information about the 13th Amendment from Wikipedia.
The Thirteenth Amendment to the United States Constitution outlaws slavery and involuntary servitude, except as punishment for a crime. It was passed by the Senate on April 8, 1864, by the House on January 31, 1865, and adopted on December 6, 1865. On December 18, Secretary of State William H. Seward proclaimed it to have been adopted. It was the first of the three Reconstruction Amendments adopted after the American Civil War.
President Lincoln and other Republicans were concerned that the Emancipation Proclamation, which in 1863 declared the freedom of slaves in ten Confederate states then in rebellion, would be seen as a temporary war measure, since it was based solely on Lincoln’s war powers. The Proclamation did not free any slaves in the border states nor did it abolish slavery.
 Because of this, Lincoln and other supporters believed that an amendment to the Constitution was needed.
Why am I bothering to post information about an amendment that was written so very long ago? Take a look and listen at this link.
