Were there actually any peasants in the Estates General of 1789? Or was it merchants, etc. ?
It's hard to say. Many of the more obscure deputies had job titles that could be applied to a peasant, but it's hard to say exactly how well off they were. More than a dozen deputies were "laboureurs", which meant a landowning farmer, and a similar number were "cultivateurs" but in some cases they also have titles that are obviously high status. Either way, they were very much outnumbered by lawyers. Wealth and privilege would have been a big advantage during the election, by making the candidate a more attractive candidate by their education, and because of the strong and pervasive bias in favor of the upper class. The cities also had more deputies than the countryside.
