What caused the French Revolution? There were many causes of the French Revolution, the overall reason was because of the nations debt and the inequality among lower class people. The clergy and nobility declined revenue and that firmed them to start paying taxes. The commoners did not like this decision which resulted in the rise of food prices. With the nations debt this caused the price of everything to increase to make up for the unpaid taxes. People of the nation were refusing to pay taxes because of the already poor nation. The enlightenment philosophies that explained the equal rights of all people, encouraged the commoners to form their own legislative body. This gained support from the people of the poor who were uprisen about the Kings decision to ride the price of foods. With the commoners starting to gain the trust of the poor, this started problems as the king realized the effects they knew thoughts of the commoners were bringing. Overall the Revolution was not successful, after control was taken over by Napoleon Bonaparte, things seemed to be going well until challenges arose. They never were able to fully establish a constitutional monarch or even a representative government for France. The success of the whole Revolution was just the spread of enlightenment ideas beyond France.
