Robespierre first entered the chat: https://en.wikipedia.org/wiki/Reign_of_Terror

Then Napoleon followed.

Make of it what you will.

[EDIT: for the downvoters - the folks who got guillotined in France were definitely bad, but the Terror was very real and very awful. It tends to be a trend with the noble overthrowers that after the initial wins they then get excited to go lop the heads off anyone else that might have ever bothered them. Be careful what you wish for.]
