I'm sorry but you're an ignorant sob who doesnt know a first thing about Poland or polish history, there were a LOT of aristocratic titles that were coupled with administrative power.
Voivod, starost, count, prince, governor, baron, chamberlain, royal chaser, royal guardian, grand lithuanian guardian, grand crown guardian, grand field guardian.
I'm sorry, but it's a real shame for someone who calls himself a "historian" to say things like that ...
The only noble title officialy recognized in the Royal Republic was the title of
szlachcic. Then the Sejm at the Union of Lublin gathering in 1569 had recognized to a handful of Lithuanian families (among them Czartoryski, for example) the use of their traditional title of prince. Hence, the rich and famous families of the Crown, like the Potocki family, had never enjoyed the title of prince in the times if the First Republic except for a few cases in which the Sejm occasionally granted such a title to someone in recognition of their merits to the Fatherland (the most prominent case of this practice was the Poniatowski family).
All the
szlachta, which used to follow almost exactly the same path of habits and traditions across the whole Polish Commonwealth, from Poznań to the deepest forests of Lithuania to the farest fields of Ukraine, regardless of their religion or wealth status, were very eager in stressing the fact that their formal status of noblemen was equal to to the formal status of their wealhy noble countrymen who enjoyed the posts of voivods, starosts etc (these had their real prices to be paid for if someone wanted them). Hence the very popular in these times (and well-known until our time) saying:
Szlachcic na zagrodzie równy wojewodzie,
which underlined the fact that wojewoda is only a simple nobleman, someone exactly like them, who may be richer than they are, but is equal to them in terms of citizenship.
In 1921, in its first Constitution of the Republic, the Polish State abandoned the idea of recognizing any titles except for professional, scientific and the like ones.
And what is being said in the family circles while celebrating the 90-th anniversary of an aunt who happens to be proud of being of the Rzewuski family, is a completely different story ...
