Пруссы
Old Prussians, Baltic Prussians or simply Prussians (Old Prussian: "prūsai"; or "Prußen"; ; ; ; ; ) were an indigenous tribe among the Baltic peoples that inhabited the region of Prussia, at the south-eastern shore of the Baltic Sea between the Vistula Lagoon to the west and the Curonian Lagoon to the east. The Old Prussians, who spoke an Indo-European language now known as Old Prussian and worshipped pagan deities, lent their name, despite very few commonalities, to the later, predominantly Low German-speaking inhabitants of the region.
