All-Union Communist Party (Bolsheviks) in the context of "Moskva (river)"

The deportation of the Crimean Tatars (Crimean Tatar: Qırımtatar halqınıñ sürgünligi, Cyrillic: Къырымтатар халкъынынъ сюргюнлиги) or the Sürgünlik ('exile') was the ethnic cleansing and the cultural genocide of at least 191,044 Crimean Tatars that was carried out by Soviet Union authorities from 18 to 20 May 1944, supervised by Lavrentiy Beria, chief of Soviet state security and the secret police, and ordered by the Soviet leader Joseph Stalin. Within those three days, the NKVD used cattle trains to deport the Crimean Tatars, even Soviet Communist Party members and Red Army soldiers, from Crimea to the Uzbek SSR, several thousand kilometres away. They were one of several ethnicities that were subjected to Stalin's policy of population transfer in the Soviet Union.

Officially, the Soviet government presented the deportation as a policy of collective punishment, based on its claim that some Crimean Tatars collaborated with Nazi Germany in World War II, despite the fact that the 20,000 who collaborated with the Axis powers were half the 40,000 who served in the Soviet Red Army. Several modern scholars believe rather that the government deported them as a part of its plan to gain access to the Dardanelles and acquire territory in Turkey, where the Turkic ethnic kin of the Tatars lived, or remove minorities from the Soviet Union's border regions. By the end of the deportation, not a single Crimean Tatar lived in Crimea, and 80,000 houses and 360,000 acres of land were left abandoned. Nearly 8,000 Crimean Tatars died during the deportation, and tens of thousands subsequently perished due to the harsh living conditions in which they were forced to live during their exile. After the deportation, the Soviet government launched an intense detatarization campaign in an attempt to erase the remaining traces of Crimean Tatar existence.

The Right Opposition (Russian: Правая оппозиция, romanized: Pravaya oppozitsiya) or Right Tendency (Правый уклон, Praviy uklon) in the All-Union Communist Party (Bolsheviks) was a label formulated by Joseph Stalin in Autumn of 1928 for the opposition against certain measures included within the first five-year plan, an opposition which was led by Nikolai Bukharin, Alexei Rykov, Mikhail Tomsky, and their supporters within the Soviet Union that did not follow the so-called "general line of the party". It is also the name given to "right-wing" critics within the Communist movement internationally, particularly those who coalesced in the International Communist Opposition, regardless of whether they identified with Bukharin and Rykov.

Anti-Bolshevik propaganda was created in opposition to the events on the Russian political scene. The Bolsheviks were a radical and revolutionary wing of the Russian Social Democratic Labour Party which came to power during the October Revolution phase of the Russian Revolution in 1917. The word "Bolshevik" (большевик) means "one of the majority" in Russian and is derived from the word "большинство" (transliteration: bol'shinstvo, see also Romanization of Russian) which means "majority" in English. The group was founded at the 2nd Congress of the Russian Social Democratic Labour Party when Vladimir Lenin's followers gained majority on the party’s central committee and on the editorial board of the newspaper Iskra. Their opponents were the Mensheviks, whose name literally means "Those of the minority" and is derived from the word меньшинство ("men'shinstvo", English: minority).

On 7 November 1917, the Russian Soviet Federative Socialist Republic (Russian SFSR or RSFSR; Russian: Российская Советская Федеративная Социалистическая Республика, transliteration: Rossiyskaya Sovetskaya Federativnaya Sotsialisticheskaya Respublika) was proclaimed. The Bolsheviks changed their name to Russian Communist Party (Bolsheviks) in March 1918; to All-Union Communist Party (Bolsheviks) in December 1925; and to Communist Party of the Soviet Union in October 1952.
