Low Prussian dialect

Low Prussian (German: Niederpreußisch), sometimes known simply as Prussian (Preußisch), is a moribund dialect of Northern Low German that developed in East Prussia. Low Prussian was spoken in East and West Prussia and Danzig up to 1945. In Danzig it formed the particular city dialect of Danzig German. It developed on a Baltic substrate through the influx of Dutch- and Low German-speaking immigrants. It supplanted Old Prussian, which became extinct in the 18th century.

Simon Dach's poem Anke van Tharaw was written in Low Prussian.
