The significance of the Declaration of the Rights of Man and of the Citizen during the French Revolution lies in its establishment of fundamental principles regarding individual rights and the role of citizens in government. Adopted in 1789, the declaration proclaimed that all men are born free and equal in rights, emphasizing liberty, property, security, and resistance to oppression. It represented a radical shift from absolute monarchy to a focus on civil liberties and popular sovereignty. This document influenced not only the French Revolution but also future democratic movements worldwide, serving as a benchmark for human rights and contributing to the development of modern democratic ideals.
