Document 2: List of leaders of the Soviet Union: Under the 1977 Constitution of the Union of Soviet Socialist Republics (USSR), the Chairman of the Council of Ministers was the head of government and the Chairman of the Presidium of the Supreme Soviet was the head of state. The office of the Chairman of the Council of Ministers was comparable to a prime minister in the First World, whereas the office of the Chairman of the Presidium was comparable to a president in the First World. In the Soviet Union's seventy - year history there was no official leader of the Soviet Union office, but during most of that era there was a de facto top leader who usually led the country through the office of the Premier or the office of the General Secretary of the Communist Party of the Soviet Union (CPSU). In the ideology of Vladimir Lenin the head of the Soviet state was a collegiate body of the vanguard party (see What Is to Be Done?).
Document 3: Germans: After World War II, eastern European countries such as the Soviet Union, Poland, Czechoslovakia, Hungary, Romania and Yugoslavia expelled the Germans from their territories. Many of those had inhabited these lands for centuries, developing a unique culture. Germans were also forced to leave the former eastern territories of Germany, which were annexed by Poland (Silesia, Pomerania, parts of Brandenburg and southern part of East Prussia) and the Soviet Union (northern part of East Prussia). Between 12 and 16,5 million ethnic Germans and German citizens were expelled westwards to allied-occupied Germany.

The Kazakh ASSR and Kirghiz ASSR were transformed into the Kazakh and Kirghiz Soviet Socialist Republics. The Karakalpak Autonomous Socialist Soviet Republic was transferred to the Uzbek SSR.
Document 5: Dissolution of the Soviet Union: In February 20, 1988, after a week of growing demonstrations in Stepanakert, capital of the Nagorno-Karabakh Autonomous Oblast (the Armenian majority area within Azerbaijan Soviet Socialist Republic), the Regional Soviet voted to secede and join with the Soviet Socialist Republic of Armenia. This local vote in a small, remote part of the Soviet Union made headlines around the world; it was an unprecedented defiance of republic and national authorities. On February 22, 1988, in what became known as the "Askeran clash", two Azerbaijanis were killed by Karabakh police. These deaths, announced on state radio, led to the Sumgait Pogrom. Between February 26 and March 1, the city of Sumgait (Azerbaijan) saw violent anti-Armenian rioting during which 32 people were killed. The authorities totally lost control and occupied the city with paratroopers and tanks; nearly all of the 14,000 Armenian residents of Sumgait fled.

Document 12: East Prussia: After the expulsion of the German population ethnic Russians, Belarusians, and Ukrainians were settled in the northern part.
