The correct answer to this open question is the following.
Some of the new ideas that became very popular after the Enlightenment led to people challenging their forms of government and exposing inequalities in their nations.
Among them were the ideas of natural rights, the social contract, and the division of powers in a government under the system of checks and balances.
These ideas came from brilliant minds who were very influential in further independence and revolutionary movements. We are talking about thinkers and philosophers such as Baron of Montesquiou, Jean-Jaques Rosseau, Thomas Hobbes, John Locke, and Voltaire.
These thinkers influenced independence movements like the American Revolutionary War and the French Revolution.
