Pomestie, "service landholding," was a parcel of land (hopefully inhabited by rent-paying peasants, later serfs [see Serfdom]) in exchange for which the holder (not owner) had to render lifelong service to the state, typically military service, but occasionally service in the government bureaucracy.
Change from Appanage to Pomestie: Take all princes land and give it out to Lords for use in order to get military service from them. He can dismiss them whenever he wants -> enlarges his army. Peasants forced into serfdom through debt service.
