peasants chłopi, but not Jews Żydzi, could and did rise to official ennoblement in Commonwealth society, although Charles-Joseph, 7th Prince of Ligne, while trying to obtain Polish noble status, is supposed to have said in 1784, According to heraldic sources 1,600 is the total estimated number of all legal ennoblements throughout the history of Kingdom of Poland and Polish–Lithuanian Commonwealth from the 14th century onward, half of which were enacted in the final years of the late 18th century.
