Old Prussian (Prūsiska bila, "Prussian language") was the principal language of the West Baltic Pruzzians (also Aestii, Pruzzi), inhabitants of East Prussia until they were Germanized after the Teutonic Order conquest (1230s-1410s). Distinct from East Baltic Lithuanian and Latvian, Old Prussian shows archaic Indo-European features lost in those languages: preservation of nominative singular -s in some classes, simpler consonant alternations, and Germanic-style declension simplification. Reconstructed primarily from three surviving Catechisms (1545-1561) and the 14th-century Elbing Vocabulary. A modern Old Prussian revival movement, led by linguists since the 1980s, attempts to make Old Prussian a usable second language.
