France's establishment of a representative government was significant as it marked a pivotal shift from absolute monarchy to a system where power derived from the will of the people. The French Revolution catalyzed this change, promoting ideals of liberty, equality, and fraternity. The introduction of the Declaration of the Rights of Man and of the Citizen underscored the principles of popular sovereignty, leading to the creation of the National Assembly. This transformation influenced other nations, inspiring movements toward democracy and national sovereignty.
