|Opposition and resistance|
Abolition of slavery occurred as abolition in specific countries, abolition of the trade in slaves and abolition throughout empires. Each of these steps was usually the result of a separate law or action.
It should be noted that many of these changes were reversed in practice over the succeeding centuries.
While now illegal everywhere, slavery or practices akin to it continue today in many countries throughout the world.
