It is a crucial issue which was often connected with emotions and political attitudes, when it was approached.

Or shall we see the Terror as an accident incompatible to democracy and the origins of the French Revolution?

Furthermore the essay will leave out the end of the `Great Terror` as well as the `White Terror`.
