The 13th Amendment is perhaps the most important amendment in American history.

Thomas Jefferson, who left a particularly complex legacy regarding slavery, signed a law banning the importation of enslaved people from Africa in 1807.

The 13th Amendment to the United States Constitution abolished slavery and involuntary servitude, except as punishment for a crime.

The amendment was passed by Congress on January 31, 1865, and ratified by the required 27 of the then 36 states on December 6, 1865 and proclaimed on December 18. The House of Representatives passed the 13th Amendment (S.J. Res. 16) by a vote of 119 to 56.

Ratified in 1865, it was the first of three "Reconstruction amendments" that were adopted immediately following the Civil War.

The 13th Amendment to the Constitution did not end discrimination against those who had been enslaved and blacks. Together with the 14th and 15th Amendments, also ratified during the Reconstruction era, the 13th Amendment sought to establish equality for black Americans.
