Ok, I admit, the unrivaled chief hero of the Revolution all of sudden revealing himself to be a reactionary and crowning himself 'First Citizen' or something (maybe even King, lol) is a little out there, but at least from an unprofessional view it seems as though Bonaparte looms like a colossus over the formative years of the Republic, he and his army seeming to save France on their own several times. I imagine there were points when Bonaparte, if he wished, could've just did what he wished and nobody would've had the strength to resist him. That he remained loyal to the constitution (insofar as he only got it changed through the odd referendum here and there) like Washington in America set a precedent that greatly strengthened the young democracy.
If he decided to march his army up to the corps législatif and ordered it dispensed, what might follow?
