Central Bureau of the Lithuanian Sections of the Russian Communist Party (Bolsheviks)
The Central Bureau of the Lithuanian Sections of the Russian Communist Party (Bolsheviks) (Lithuanian: RKP(b) Lietuvių sekcijų Centro Biuras) was an organization within the Russian Communist Party (Bolsheviks) that coordinated groups of Lithuanian party members across Soviet Russia in 1917–1921. The Central Bureau played a key role in the formation of the communist movement in Lithuania in the lead-up to the establishment of the first Lithuanian Soviet Republic in 1918, as there was no communist movement there at the time of the October Revolution.
