The answer to the question: Why would those who started the French Revolution and created the famous "Declaraction of the Rights of Man and of the Citizen", say that the revolution was not successful, would be, that despite the document and what it said, how it established the rights of people, their freedom, and sought to initiate the passage from absolute monarchy to democracy, the truth was that in France, this Declaration did not change their reality, especially not in government style. This means, the French went from being ruled by King Louis XVI, to being ruled again by the military dictatorship, and later kingship, of Napoleon Bonaparte.

Explanation:

The "Declaration of the Rights of Man and of the Citizen" was among the first documents ever created where the civil rights, and civil liberties of people, as well as the ideal of democracy vs. monarchy, was set down in paper. Set by the French National Constituent Assembly, in 1789, after the French Revolution, its intention was to establish the framework that would now rule the fates of the French people, who were supposed to be now free from violence, the violation of their rights, and from the absolute monarchy. In reality, after the Revolution France did not have a simple passage from confrontation into peace, and in the end, their goverment passed from being led by Louis XVI, to the hands of Napoleon Bonaparte, who assumed the control of a military dictatorship, and would later be crowned as emperor. So the changes proposed by the Declaration, were in truth, not met, until much later.

Explanation:The Declaration of the Rights of Man and of the Citizen (French: Déclaration des droits de l'homme et du citoyen de 1789), set by France's National Constituent Assembly in 1789, is a human civil rights document from the French Revolution.[1]

The Declaration was drafted by the Abbé Sieyès and the Marquis de Lafayette, in consultation with Thomas Jefferson.[2] Influenced by the doctrine of "natural right", the rights of man are held to be universal: valid at all times and in every place, pertaining to human nature itself. It became the basis for a nation of free individuals protected equally by the law. It is included in the beginning of the constitutions of both the Fourth French Republic (1946) and Fifth Republic (1958) and is still current. Inspired by the Enlightenment philosophers, the Declaration was a core statement of the values of the French Revolution and had a major impact on the development of freedom and democracy in Europe and worldwide.[3]

The 1789 Declaration, together with the 1215 Magna Carta, the 1689 English Bill of Rights (1689), the 1776 United States Declaration of Independence, and the 1789 United States Bill of Rights, inspired in large part the 1948 United Nations Universal Declaration of Human Rights
