Old Prussian

Old Prussian was one of the Baltic languages , spoken by the original population of Prussia.

Old Prussian began to be written down in about the 12th century AD, when literate Germans and Poles began to move into Prussian territory. However, these new immigrants also caused a slow decline in the Old Prussian language as Prussians began to adopt the languages of the newcomers. Old Prussian probably ceased to be spoken in the 17th century or thereabouts.

A fair bit of literature in the Old Prussian language survives, and can still be read by the few scholars who have studied the language.

Further information is in the Old Prussian language article. The information here should probably be moved over to that page.
