Robespierre ruled only parts of France, and for only a brief period. He was a cruel fanatic, a revolutionary who only destroyed.
Unlike Napoleon, Robespierre was not a builder or innovator, and he had none of Napoleon's magnanimity to balance his destructive side.
That is true.
Robespierre was a kind of Khomeini of his era: a bloodthirsty „theocrat“ who could destroy but was unable to build, unable to compromise.
That was going to be his undoing.
