Soviet government in the context of Silayev's Government

The Soviet invasion of Poland was a military conflict by the Soviet Union without a formal declaration of war. On 17 September 1939, the Soviet Union invaded Poland from the east, 16 days after Nazi Germany invaded Poland from the west. Subsequent military operations lasted for the following 20 days and ended on 6 October 1939 with the two-way division and annexation of the entire territory of the Second Polish Republic by Nazi Germany and the Soviet Union. This division is sometimes called the Fourth Partition of Poland. The Soviet (as well as German) invasion of Poland was indirectly indicated in the "secret protocol" of the Molotov–Ribbentrop Pact signed on 23 August 1939, which divided Poland into "spheres of influence" of the two powers. German and Soviet cooperation in the invasion of Poland has been described as co-belligerence.

The Red Army, which vastly outnumbered the Polish defenders, achieved its targets, encountering only limited resistance. Some 320,000 Poles were made prisoners of war. The campaign of mass persecution in the newly acquired areas began immediately. In November 1939 the Soviet government annexed the entire Polish territory under its control. Some 13.5 million Polish citizens who fell under the military occupation were made Soviet subjects following show elections conducted by the NKVD secret police in an atmosphere of terror, the results of which were used to legitimise the use of force. A Soviet campaign of political murders and other forms of repression, targeting Polish figures of authority such as military officers, police, and priests, began with a wave of arrests and summary executions. The Soviet NKVD sent hundreds of thousands of people from eastern Poland to Siberia and other remote parts of the Soviet Union in four major waves of deportation between 1939 and 1941.Soviet forces occupied eastern Poland until the summer of 1941 when Germany terminated its earlier pact with the Soviet Union and invaded the Soviet Union under the code name Operation Barbarossa. The area was under German occupation until the Red Army reconquered it in the summer of 1944. An agreement at the Yalta Conference permitted the Soviet Union to annex territories close to the Curzon Line (which almost coincided with all of their Molotov–Ribbentrop Pact portion of the Second Polish Republic), compensating the Polish People's Republic with the greater southern part of East Prussia and territories east of the Oder–Neisse line. The Soviet Union appended the annexed territories to the Ukrainian, Byelorussian and Lithuanian Soviet Socialist Republics.

Mikhail Afanasyevich Bulgakov (/bʊlˈɡɑːkɒf/ buul-GAH-kof; Russian: Михаил Афанасьевич Булгаков, IPA: [mʲɪxɐˈil ɐfɐˈnasʲjɪvʲɪdʑ bʊlˈɡakəf] 15 May [O.S. 3 May] 1891 – 10 March 1940) was a Russian and Soviet novelist and playwright. His novel The Master and Margarita, published posthumously, has been called one of the masterpieces of the 20th century. He also wrote the novel The White Guard and the plays Ivan Vasilievich, Flight (also called The Run), and The Days of the Turbins.

Some of his works (Flight, all his works between 1922 and 1926, and others) were banned by the Soviet government, and personally by Joseph Stalin, after it was decided by them that they "glorified emigration and White generals". On the other hand, Stalin loved Bulgakov's dramatization of The White Guard, anodynely renamed The Days of the Turbins. The Soviet leader reportedly attended the play at least 15 times, even calling a theater to personally demand its production after the playwright's fall from favor. Despite Stalin's intercession in this and other matters Bulgakov was only briefly successful during his lifetime. After his death, especially once the publication of The Master and Margarita had been accomplished in 1966-67, his work was reassessed. He is now widely regarded as one of the great Russian authors of the 20th century.

Bolshevization of the Communist International has at least two meanings. First it meant to independently change the way of working of new communist parties, such as the Communist Party of Great Britain (CPGB) in the early 1920s. Secondly was the process from 1924 by which the pluralistic Communist International (Comintern) and its constituent Communist parties were increasingly subject to pressure by the Soviet government in Moscow. With the development within Soviet Communism of Marxism–Leninism under Joseph Stalin, this latter Bolshevization became more clearly Stalinization. The autonomy of national Communist parties was downplayed and the Comintern became a tool of Soviet foreign policy.

Patriarch Sergius I (Russian: Патриа́рх Се́ргий; born Ivan Nikolayevich Stragorodsky, Ива́н Никола́евич Страгоро́дский; January 23 [O.S. January 11] 1867 – May 15, 1944) was the 12th Patriarch of Moscow and all the Rus', from September 8, 1943 until his death on May 15, 1944. He was also the de facto head of the Russian Orthodox Church in 1925–1943, firstly as deputy Patriarchal locum tenens (1925–1937) subsequently as Patriarchal locum tenens (1937–1943).

Starting in 1927, he pursued a policy of unconditional loyalty to the Soviet government, which led to significant criticism of him and the separation of some lay people and clerics.

Eduard Ambrosis dze Shevardnadze (Georgian: ედუარდ ამბროსის ძე შევარდნაძე; 25 January 1928 – 7 July 2014) was a Soviet and Georgian politician and diplomat who governed Georgia for several non-consecutive periods from 1972 until his resignation in 2003 and also served as the final Soviet minister of foreign affairs from 1985 to 1991.

Shevardnadze started his political career in the late 1940s as a leading member of his local Komsomol organisation. He was later appointed its Second Secretary, then its First Secretary. His rise in the Georgian Soviet hierarchy continued until 1961, when he was demoted after insulting a senior official. After spending two years in obscurity, Shevardnadze returned as the First Secretary of a Tbilisi city district, and was able to charge the Tbilisi First Secretary at the time with corruption. His anti-corruption work quickly garnered the interest of the Soviet government and Shevardnadze was appointed as First Deputy of the Ministry of Internal Affairs of the Georgian SSR. He would later become the head of the internal affairs ministry and was able to charge First Secretary (leader of Soviet Georgia) Vasil Mzhavanadze with corruption.
