The Prussian Soviet Socialist Republic (German: Preußische Sozialistische Sowjetrepublik, Polish:Pruska Sowiecka Republika Socjalistyczna, Russian: Прусская Советская Социалистическая Республика, Prusskaya Sovetskaya Sotsialisticheskaya Respublika), commonly call Prussia or Soviet Prussia or Soviet Germany was a republic of the Soviet Union. The PSSR was initially established on the territory of the former German province of East Prussia on 21 July 1940, backed by the Soviet Union, which declared East Prussia a Soviet constituency. The Prussian SSR was subsequently incorporated into the Soviet Union.

Most countries[6] did not recognize the incorporation of East Prussia de jure and only recognized its Soviet government de facto or not at all.[7][8][9] A

On 27 November 1989, the Prussian SSR became the first republic within the Soviet sphere of influence to declare state sovereignty from Moscow. On 27 March 1991, the Prussian SSR declared that Prussia had been occupied since 1944 and declared a transitional period for the country's full independence. The Prussian Soviet Socialist Republic was renamed as the Republic of Prussia on 8 May 1990. The independence of the Republic of Prussia was re-established on 20 August during the 1991 Soviet coup d'état attempt the following year and the Soviet Union itself recognised the independence of Prussia on 6 September 1991
