A crisis over slavery and the survival of the Union developed into civil war, changing the structure of the country and advancing the abolition of slavery at the constitutional level.

An imagined nineteenth-century industrial street: a printing shop, pedestrians, carts and a distant steam railway form one continuous scene.

The story

The U.S. Civil War lasted from 1861 to 1865, with slavery at the heart of the crisis. Lincoln's Emancipation Proclamation took effect on January 1, 1863, but applied mainly to designated areas still in rebellion and did not immediately end slavery nationwide. The Thirteenth Amendment, ratified on December 6, 1865, prohibited slavery and involuntary servitude across the country, while retaining an exception for punishment following lawful conviction. Legal abolition did not immediately achieve racial equality, and postwar Reconstruction and struggles against discrimination continued. The map uses Washington, the federal capital, as a representative point.

Elsewhere in the world

Comparisons with Haitian independence in 1804, Brazilian abolition in 1888, and the U.S. Civil Rights Act of 1964 can show how rights to freedom emerged through different political and social processes.
