Final answer:
The Enlightenment political revolutions brought about ideas of natural rights, liberty, and equality, which led to a growing criticism of the institution of slavery. Enlightenment thinkers argued for the abolition of slavery based on the principles of human rights and freedom. The abolitionist movement emerged as a result, eventually leading to the end of slavery in many parts of the world.
Step-by-step explanation:
The Enlightenment political revolutions had a significant impact on the institution of slavery and social distinctions. The Enlightenment brought about ideas of natural rights, liberty, and equality, which led to a growing criticism of the institution of slavery. Enlightenment thinkers such as John Locke and Jean-Jacques Rousseau argued that all individuals should have certain inalienable rights, including the right to freedom. These ideas and debates sparked the abolitionist movement in various countries, leading to the eventual abolition of slavery in many parts of the world. However, it is important to note that the Enlightenment ideals of rights and freedoms coexisted with racial injustices, and the complete eradication of slavery took many years of continued struggle.
