Prussians

Prussians, Old Prussians, or Peuczi, the western division of the Lithuanians (q.v.), who originally occupied the region between the Vistula and Niemen - that is, part of West and the whole of East Prussia. As a separate nationality these Prussians became extinct or absorbed in the surrounding German populations about 250 years ago. Of their Lithuanian dialect, which died out towards the middle of the 17th century, nothing survives except a vocabulary of over 800 words dating from the beginning of the 15th century, and a translation of the German catechism published in 1561. Prussian was of more archaic type than Lettic, and even preserved some forms older than those of Lithuanian itself.
