The French revolution was very important for France, but also for the rest of the world.
The reason why it had such big influence was that the French people with their revolution showed the world that the power of the nation is in the people, and if everyone sticks together the leaders can not do anything against them.
That prompted lot of revolutions around the world, big portion of which will similar outcomes, while some, unfortunately, ended up in a situation similar or even worse prior to their revolutions.
