Why was France more susceptible to revolutionary sentiment in the 18th and 19th centuries than other countries were?

You had the Poles too(don't know much about Poland/Lithuania, it's my blind spot in Euro history but it sure wasn't a monarchy),
Oh no, it was a monarchy alright. The kings might have had no power, but they weren't gotten rid of. That is until Poland's neighbours carved it up and swallowed the pieces. And even when attempting Polands restoration that came with kings again.
