Even the French revolution didn't just suddenly happen, hundreds of years of starting to understand how terrible monarchy was and building the knowledge of alternate systems among the general populace was required. The real change is people gaining more knowledge, gaining a better understanding of reality, themselves.

Maybe take some time away from math to learn about history and revolution. YOU don't really get it. The French revolution definitely wasn't people slowly learning that Monarchy is bad over hundreds of years. The Monarchy didn't have power because people didn't know better. Monarchies existed on purpose and they were maintained against the will of the lower class. They knew it was bad. The labor knew it was bad immediately. The society at whole didn't care that it was bad because it either didn't affect them or they benefited from it.
