What social and political changes resulted from the american and french revolutions?

It put new parties in power that in the American case would give them the independence to do as they wished. However, in the French case, afterwards, noone picked up the reigns for a few years, which plunged France into chaos. However, afterwards, they finally got a new leader, which threw them onto the global power playing board with the help of Napolean, which helped to make them into a Great Power.

Ifeel like this is a very good quesyion
