Abolition of slavery timeline

Proclamation of the Abolition of Slavery in the French Colonies 1849, by Francois Auguste Biard. Versailles Palace

The abolition of slavery occurred at different times in different countries, and sometimes occurred sequentially in more than one stage: for example, as abolition of the trade in slaves in a specific country, and then as abolition of slavery throughout empires. Each step was usually the result of a separate law or action. This timeline shows abolition laws or actions listed chronologically.

This article also covers the abolition of serfdom.

Although slavery is now abolished de jure in all countries, some practices akin to it continue today in many places throughout the world.

Ancient times

• 9-12 A.D.: Wang Mang, first and only emperor of the Xin Dynasty, usurped the Chinese throne and instituted a series of sweeping reforms, including the abolition of slavery and radical land reform from 9-12 A.D.^[3][4]
