The Declaration of the Rights of Man and Citizen was approved on August 26, 1789 by the National Assembly. This declaration was a declaration of the rights men should have in the country of France. The Declaration of the Rights of Man and Citizen has argued to have been another document which laid the foundations for the human rights we know today (Other than our constitution). Nationalism became an emerged in the Revolution and spread throughout Europe and promoted change. The most significant of these changes was democracy.
On Apr. 20, 1792, France declared war on Austria. The French armies lacked organization and good leadership so they were flawed in this way. Austrian and Prussian forces crossed the frontier and began to march on Paris. The duke issued a manifesto threatening to raze Paris should the royal family be harmed. This manifesto angered the French and contributed to the suspension of the king. The comte de Rochambeau, commanding the northern sector, and the marquis de Lafayette, commanding the center, resigned. Their able successors, the generals Dumouriez and Kellermann, turned the tide when they repulsed the invaders at Valmy.
The abolition of the feudal system took place on September 21 1792. This took power away from the first and second estates and gave equality to the third. This was a step to starting the revolution because the wealthy no longer had power. The wealthy were frustrated about this because they no longer had power over the third estate, and there were no more estates.
The Reign of Terror was a period of time where Robespierre ruled the country and changed many things about society. He closed all religious institutions (Catholic and Protestant Churches) and outlawed the practice of religion. Robespierre took the day Sunday out of the calendar because he wanted this to enforce the banning of worship. Robespierre changed the entire calendar and changed the units of time. He also removed all traces of the past and archived art. He did this in order to shelter the people and enforce the ideas of the Enlightenment on them.
Robespierre's fall happened a little under a year after he took power. This happened because the people were sick of his strict rule. He was executed after he was overthrown. This played an important role in the revolution because it depicts the fact that strict dictatorship does not solve revolution, rather fuels it.
