Established royal families of Europe regarded the Bonaparte family as "parvenu" royalty. She despised her brother-in-law as a parvenu and for his callousness towards his grandchildren. Le Paysan parvenu is an unfinished novel by Pierre de Marivaux. Maybe they did this out of envy, unable to endure the boasting parvenu. Other interpretations have seen in the two protagonists caricatures of political corruption and "parvenu" morals. In 1735 another novel, "Le Paysan parvenu", was begun, but this also was left unfinished. A parvenu is a person who is a relative newcomer to a socioeconomic class.
