One of the most important result of the French Revolution was that Political power shifted to the bourgeoisie (Middle class people).

The Great French Revolution of 1789 not only overthrew the monarchy in France, but ultimately led to the destruction of the Old Order across Europe.

The bourgeoisie gained an enormous amount of political power when the National Assembly issued the Declaration of the Rights of Man, and drafted a new constitution for France.
