The French Revolution was caused by the Monarchy in debt. The seven year battle of the American revolution the French government was deeply in debt. Then, philosophies that emphasizes the equality of all people. Commoners formed there own legislative body, which helped earn support from the poor who were upset the king raised the prices for food. Also there was social inequality. conflict between the Monarchy and nobility over the reforms of the tax system led to paralysis and bankruptcy.
The French Revolution was a success because Napolean completely outsmarted the French using there greed against them. Napolean knew that the French wanted to make there victory an exceptional victory, so Napolean acted like they were losing and he told his men to stop firing and act like they are losing the war so there whole army can come and start rushing them, not knowing the Russians were coming right behind them to ambush them from every direction. I gotta say that's a good victory. The French Revolution also failed to establish a constitutional monarchy or representative government. One of the most important outcomes of the French Revolution is that many citizens got a taste of liberty, equality, and power, however it didn't last long.
