Anti-slavery refers to the movement and efforts aimed at ending the practice of slavery, where individuals are forced to work without pay and are treated as property. This movement gained significant momentum in the 18th and 19th centuries, particularly in Europe and North America, as people began to recognize the moral and ethical implications of enslaving others. Key figures in the anti-slavery movement include Frederick Douglass, an escaped slave who became a prominent activist, and William Wilberforce, a British politician who played a crucial role in abolishing the slave trade in Britain. The movement ultimately led to the abolition of slavery in many countries, promoting human rights and equality.
