The German revolution of 1918, the abolition of the Treaty of Brest-Litovsk and the rebirth of Polish state rose again the problem of Russia’s West territories (Lithuanian and Belorussian). Bolsheviks proclaimed the right of nations to self-determination but did not want to lose control over these territories. In opposition to the Polish federative conception, they decided to create the buffer Soviet states and proclaimed the Lithuanian Soviet Republic in December 1918 and in January 1919 the Socialist Soviet Republic of Belorussia. Their plan was to redress the Polish territorial claims to these supposedly independent states. Soviet politicians were ready to let Poland have only the Bialystok district on condition that they recognize the Soviet governments and establish diplomatic relations. In addition, in this period they negotiated with Entente’s representative and hoped to be recognized by the great powers. The consolidation of the Belorussian and Lithuanian Republics was a result of disagreement of national problems in the Belorussian government and its discussions with the Lithuanian communists. The territory of Belorussia was reduced. The plans of Soviet establishment were canceled by Polish intervention.
