13th Amendment: Abolition of Slavery (1865)Passed by Congress on January 31, 1865, and ratified on December 6, 1865, the 13th Amendment abolished slavery in the United States. Lincoln recognized that the Emancipation Proclamation would have to be followed by a constitutional amendment in order to guarantee the abolishment of slavery.He insisted that passage of the 13th Amendment be added to the Republican Party platform for the upcoming 1864 Presidential election. His efforts met with success when the House passed the bill in January 1865 with a vote of 119–56. On February 1, 1865, President Abraham Lincoln approved the Joint Resolution of Congress submitting the proposed amendment to the state legislatures. The necessary number of states (three-fourths) ratified it by December 6, 1865. With the adoption of the 13th Amendment, the United States found a final constitutional solution to the issue of slavery. The 13th Amendment, along with the 14th and 15th, is one of the trio of Civil War amendments that greatly expanded the civil rights of Americans.
Note: A portion of Article IV, section 2, of the Constitution was superseded by the 13th Amendment.
