Union of Slavic Forces of Russia
The Union of Slavic Forces of Russia (USSR; Russian: Союз славянских сил Руси; СССР; Soyuz slavyanskikh sil Rusi, SSSR), also known by various other names, are a network of conspiracy theory-oriented political groups across Russia and the post-Soviet states whose supporters believe that the dissolution of the Soviet Union was illegal and invalid and that the USSR (or Russian Empire) continues to exist as a legal entity in international law; as a result, they believe the present Russian Federation illegitimate. Adherents promote various conspiracy theories.
