When was slavery abolished in usa?

Slavery was officially abolished in the United States by the 13th Amendment to the US Constitution, which was adopted on December 6, 1865.

The amendment states that “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.” This amendment followed the Emancipation Proclamation, which was issued by President Abraham Lincoln on January 1, 1863, during the American Civil War, and declared all slaves in the Confederate states “forever free.” However, the 13th Amendment officially abolished slavery throughout the entire United States, and it remains a significant milestone in American history.
