What developments in France and the US attempted to assure the implementation of this concept of government?

In both France and the United States, the Enlightenment ideals significantly influenced the development of democratic governance. In the U.S., the Constitution and the Bill of Rights established a framework for protecting individual liberties and limiting governmental power. Meanwhile, the French Revolution sought to implement these principles through the Declaration of the Rights of Man and of the Citizen, which emphasized equality and popular sovereignty. Both nations focused on creating systems of checks and balances to prevent tyranny and ensure the voice of the people in government.
