The Declaration of the Rights of the Peoples of Russia (Russian: Деклара́ция прав наро́дов Росси́и) was a document promulgated by the Bolshevik government of Russia on November 15 (November 2 by Old Style), 1917 (signed by Vladimir Lenin and Joseph Stalin).
The document proclaimed:
The meaning of the Declaration is still disputed in Russian historiography. In 1917 the Bolshevist thinking was still largely idealistic, dominated by vague ideas of "universal happiness". Also, at that moment Bolsheviks believed that the World revolution was imminent, so they did not care much about loss of territories.
However, in the cold-war western literature, it is often argued that in fact Lenin and Stalin agreed to liberate mostly the territories they had no sovereignty over since Russia had lost them to Central Powers in 1915 and 1916. Many historians suggest that the purpose of the document was to limit the public dissent after Russia lost most of its western areas and try to complicate the matters behind the front lines.
But in reality, the declaration had the effect of rallying some ethnic non-Russians behind the Bolsheviks. Latvian riflemen were important supporters of Bolsheviks in the early days of Russian Civil War and Latvian historians recognize the promise of sovereignty as an important reason for that. White Russians did not support self-determination and, as a result, few Latvians fought on the White side.
Actually, the right of secession was soon exercised by many nations that earlier had been incorporated into Imperial Russia. Many areas in Russia itself were also declared independent republics. Bolshevist Russia would, however, attempt to establish Soviet power in as many of those as possible. All three Baltic states experienced wars between Soviet governments aiming to establish a Communist state allied with Bolshevist Russia and non-Communist governments aiming for an independent state. The Soviet governments received direct military support from Russia. After the non-Communist side won, Russia recognized them as the legitimate governments of the Baltic states in 1920.
