## Reasons for Slavery Being Abolished

At the forefront of the Age of Enlightenment, slavery's extinction coincides with the new concept of equality, influenced by the American, French and the Bolshevik revolutions. The idea of the working class being equal to the upper class was an idea that the working class endorsed, and considering the working class was over 90% of the population, it was the decision of the majority. With the addition of working class representatives in British parliament, labor laws were soon enforced. Britain's position of a colonial superpower likely influenced smaller countries' position on the matter.
