Constitutional revolutions refer to significant changes in a country's political structure that result in the establishment or alteration of a constitution. These revolutions often arise from widespread demands for democratic governance, civil rights, and the rule of law. They can lead to the creation of new governmental frameworks that reflect the will of the people, as seen in various historical contexts. Examples of constitutional revolutions include the American Revolution and the French Revolution, both of which sought to replace monarchical systems with democratic principles. These movements typically involve popular uprisings, political debates, and the drafting of new legal documents that define the rights and responsibilities of citizens and the government.
