リトアニア共産党
The party was working illegally until 1940. During the same year, the party amalgamated with the Communist Party of the Soviet Union (Bolsheviks). By the time of the formation of the Lithuanian SSR, the Communist Party of Lithuania (LKP) was headed by Antanas Sniečkus. In 1940, the LKP merged into the CPSU(b). The territorial organisation of the party in Lithuania was called Communist Party of Lithuania (bolshevik) (LK(b)P). In the Lithuanian territorial organisation, the first secretary of the Central Committee of the party (always a Lithuanian) was de facto governor of the country. The second secretary was always a Moscow-appointed Russian. In 1952 the name of the old Lithuanian party, LKP, was re-adopted.
