The main coat of arms of Prussia, as well as the flag of Prussia, depicted a black eagle on a white background.

The black and white national colours were already used by the Teutonic Knights and by the Hohenzollern dynasty. The Teutonic Order wore a white coat embroidered with a black cross with gold insert and black imperial eagle. The combination of the black and white colours with the white and red Hanseatic colours of the free cities Bremen, Hamburg and Lübeck, as well as of Brandenburg, resulted in the black-white-red commercial flag of the North German Confederation, which became the flag of the German Empire in 1871.

Suum cuique ("to each, his own"), the motto of the Order of the Black Eagle created by King Frederick I in 1701, was often associated with the whole of Prussia. The Iron Cross, a military decoration created by King Frederick William III in 1813, was also commonly associated with the country. The region, originally populated by Baltic Old Prussians who were Christianised, became a favoured location for immigration by (later mainly Protestant) Germans (see Ostsiedlung), as well as Poles and Lithuanians along the border regions.
