Ratified in December 1865, it specifically states that neither slavery nor involuntary servitude, except as punishment for a crime, shall exist within the United States, or any place subject to their jurisdiction. This amendment was a significant milestone in American history, marking the formal end of legal slavery and a fundamental shift towards civil rights for African Americans.

The other amendments mentioned focus on different aspects of rights and liberties. The 15th Amendment addresses voting rights, ensuring that the right to vote cannot be denied based on race. The 19th Amendment guarantees women the right to vote, representing a significant victory for women's suffrage.
