Hey there! I'm happy to help!
The French Revolution ended up unifying France in the end it helped Napoleon Bonaparte come into power as he was a war hero in the Revolution that ended up becoming the French leader.
Napoleon being the leader led to the Napoleonic Wars, where the French basically started to beat up the other European countries. They had much more power now and had much more influence than other European countries at this point.
I hope that this helps! Have a wonderful day! :D
