According to a widely accepted interpretation of the "Conversion", Pribina was initially the ruler of an independent polity which was centered on Nitra. For instance, Barford writes that Pribina "was apparently prince of Nitra". Pribina's assumed realm is described as the "first demonstrable Slavic state north of the middle Danube" by Lukačka. Lukačka also says that Pribina had a retinue and that most its members "certainly descended from the former tribal aristocracy" but some of them "could have come from the free strata of the mass of the people". Richard Marsina says that it "can hardly be unambiguously decided whether Pribina was a prince of a greater tribe or of two or three smaller joined tribes". He adds that Pribina may have belonged to the second or third generation of the heads of this polity, which emerged in the valleys of the rivers Hron, Nitra, and Váh.
