`  This article lacks some important data. First, term Old Prussians was created by german historians in 19 century (by Johannes Voigt ?) to separate novadays Prussians and Prussians of the past. Second, Old Prussians not named itselves as Prussians, it was exonym, Bartians named themselves as Bartians, Sambians - as Sambians etc. Old Prussian were organized into one or less ethnicity in the Monastic state of the Teutonic Knights, in the same time germans in this state begun to name itselves as Prussians. Third, etimology of name Prussians is unclear, one theory says it is related to frisians. Anyway, main meaning Prussians refers to inhabitans of former Prussia and I wonder why when is typed ``Prussians`` redirects to Old Prussians, and when is typed: ``Bavarians`` appears disambiguation page with links to Bavaria, but not to ancient Boii tribe?  `
