This question is about history:

what was revolutionary about the french revolution?

I need arguments and clear ideas about this topic. Thank you!

Beheading the king, replacing a thousand-year-old monarchy with a
republican system, killing thousands of people and finally covering
all of Europe with death and terror is rather revolutionary, I'd say.

Yes, Scriptor, but wasn't the Revolution all about avoiding doing your
own homework, but letting other people do it, thus building the French
middle class?

Indeed, Politicalguru! I believe that's how Napoleon became emperor as
a result of the Revolution - he had others who did his homework, for
ridiculously low pay.
