The East European Plain (also called the Russian Plain, or historically the Sarmatic Plain) is a vast interior plain extending east of the North European Plain, and comprising several plateaus stretching roughly from 25 degrees longitude eastward. It includes Volhynian-Podolian Upland on its westernmost fringe, the Central Russian Upland, and, on the eastern border, encompasses the Volga Upland. The plain includes also a series of major river basins such as the Dnieper Lowland, the Oka–Don Lowland, and the Volga Basin. At the southeastern point of the East European Plain are the Caucasus and Crimean mountain ranges. Together with the North European Plain (covering much of Belgium, the Netherlands, Denmark, Germany and Poland), and covering the Baltic states (Estonia, Latvia and Lithuania), European Russia, Belarus, Ukraine, Moldova, southeastern Romania, and, at its southernmost point, the Danubian Plain in Northern Bulgaria (including Ludogorie and Southern Dobruja), it constitutes the majority of the Great European Plain (European Plain), the greatest mountain-free part of the European landscape. The plain spans approximately 4,000,000 km (2,000,000 sq mi) and averages about 170 m (560 ft) in elevation. The highest point of the plain (480 metres (1,574.8 ft)) is in the Bugulma-Belebey Upland, in the Eastern part of the plain, in the elevated area by the Ural Mountains (priyralie).

The Grand Duchy of Lithuania was a sovereign state in northeastern Europe that existed from the 13th century, succeeding the Kingdom of Lithuania, to the late 18th century, when the territory was suppressed during the 1795 partitions of Poland–Lithuania. The state was founded by Lithuanians, who were at the time a polytheistic nation of several united Baltic tribes from Aukštaitija. By 1440 the grand duchy had become the largest European state, controlling an area from the Baltic Sea in the north to the Black Sea in the south.

The grand duchy expanded to include large portions of the former Kievan Rus' and other neighbouring states, including what is now Belarus, Lithuania, most of Ukraine as well as parts of Latvia, Moldova, Poland and Russia. At its greatest extent, in the 15th century, it was the largest state in Europe. It was a multi-ethnic and multiconfessional state, with great diversity in languages, religion, and cultural heritage.

Belarus, officially the Republic of Belarus, is a landlocked country in Eastern Europe. It is bordered by Russia to the east and northeast, Ukraine to the south, Poland to the west, and Lithuania and Latvia to the northwest. Belarus spans an area of 207,600 square kilometres (80,200 sq mi) with a population of 9.1 million. The country has a hemiboreal climate and is administratively divided into six regions. Minsk is the capital and largest city; it is administered separately as a city with special status.

For most of the medieval period, the lands of modern-day Belarus was ruled by independent city-states such as the Principality of Polotsk. Around 1300 these lands came fully under the Grand Duchy of Lithuania and subsequently by the Polish–Lithuanian Commonwealth; this period lasted for 500 years until the 1792-1795 partitions of Poland-Lithuania placed Belarus within the Russian Empire for the first time. In the aftermath of the Russian Revolution in 1917, different states arose competing for legitimacy amid the Civil War, ultimately ending in the rise of the Byelorussian SSR, which became a founding constituent republic of the Soviet Union in 1922. After the Polish-Soviet War (1918–1921), Belarus lost almost half of its territory to Poland. Much of the borders of Belarus took their modern shape in 1939, when some lands of the Second Polish Republic were reintegrated into it after the Soviet invasion of Poland, and were finalized after World War II. During World War II, military operations devastated Belarus, which lost about a quarter of its population and half of its economic resources. In 1945, the Byelorussian SSR became a founding member of the United Nations, along with the Soviet Union. The republic was home to a widespread and diverse anti-Nazi insurgent movement which dominated politics until well into the 1970s, overseeing Belarus's transformation from an agrarian to an industrial economy.

The Molotov–Ribbentrop Pact, officially the Treaty of Non-Aggression between Germany and the Union of Soviet Socialist Republics, and also known as the Hitler–Stalin Pact, the Berlin–Moscow Pact and the Nazi–Soviet Pact, was a non-aggression pact between Nazi Germany and the Soviet Union, with a secret protocol establishing Soviet and German spheres of influence across Eastern Europe. The pact was signed in Moscow on 24 August 1939 (backdated 23 August 1939) by Soviet Foreign Minister Vyacheslav Molotov and German Foreign Minister Joachim von Ribbentrop.

Tripartite discussions between the Soviet Union, the United Kingdom and France had broken down after the Soviet Union was excluded from the Munich Agreement in September 1938. Joseph Stalin, the General Secretary of the Communist Party of the Soviet Union, had indicated that the USSR was willing to support Czechoslovakia militarily if France did so as well. Subsequently, rapprochement between Soviet Union and Nazi Germany began in early 1939. Later that year the Soviet-German pact was agreed, committing both sides to neither aid nor ally itself with an enemy of the other for the following 10 years. Under the Secret Additional Protocol of 23 August 1939, Germany and the Soviet Union agreed to partition Poland; Latvia, Estonia, Finland and Bessarabia were allotted to the Soviet sphere, while Lithuania – apart from the Vilnius region, whose "interests" were recognized – lay in the German sphere (Lithuania – including the Vilnius region, but excluding a strip of land – was only transferred to the Soviet sphere by the 28 September 1939 Boundary and Friendship Treaty). In the west, rumored existence of the Secret Protocol was proven only when it was made public during the Nuremberg trials.

The Baltic states—Estonia, Latvia and Lithuania—were occupied and annexed by the Soviet Union in 1940 and remained under its control until its dissolution in 1991. For a period of several years during World War II, Nazi Germany occupied the Baltic states after it invaded the Soviet Union in 1941.

The initial Soviet invasion and occupation of the Baltic states began in June 1940 under the Molotov–Ribbentrop Pact, made between the Soviet Union and Nazi Germany in August 1939, before the outbreak of World War II. The three independent Baltic countries were annexed as constituent Republics of the Soviet Union in August 1940. Most Western countries did not recognise this annexation, and considered it illegal. In July 1941, the occupation of the Baltic states by Nazi Germany took place, just weeks after its invasion of the Soviet Union. The Third Reich incorporated them into its Reichskommissariat Ostland. In 1944, the Soviet Union recaptured most of the Baltic states as a result of the Red Army's Baltic Offensive, trapping the remaining German forces in the Courland Pocket until their formal surrender in May 1945.

The Uralic languages (/jʊəˈrælɪk/ yoor-AL-ik), sometimes called the Uralian languages (/jʊəˈreɪliən/ yoor-AY-lee-ən), are spoken predominantly in Europe and North Asia. The Uralic languages with the most native speakers are Hungarian, Finnish, and Estonian. Other languages with speakers above 100,000 are Erzya, Moksha, Mari, Udmurt and Komi spoken in the European parts of the Russian Federation. Still smaller minority languages are Sámi languages of the northern Fennoscandia; other members of the Finnic languages, ranging from Livonian in northern Latvia to Karelian in northwesternmost Russia; the Samoyedic languages and the other members of the Ugric languages, Mansi and Khanty spoken in Western Siberia.

The name Uralic derives from the family's purported "original homeland" (Urheimat) hypothesized to have been somewhere in the vicinity of the Ural Mountains, and was first proposed by Julius Klaproth in Asia Polyglotta (1823).

The Baltic states or the Baltic countries is a geopolitical term encompassing Estonia, Latvia, and Lithuania. All three countries are members of NATO, the European Union, the Eurozone, and the OECD. The three sovereign states on the eastern coast of the Baltic Sea are sometimes referred to as the "Baltic nations", less often and in historical circumstances also as the "Baltic republics", the "Baltic lands", or simply the Baltics.

All three Baltic countries are classified as high-income economies by the World Bank and maintain a very high Human Development Index. The three governments engage in intergovernmental and parliamentary cooperation. There is also frequent cooperation in foreign and security policy, defence, energy, and transportation.

The post-Soviet states, also referred to as the former Soviet Union or the former Soviet republics, are the independent sovereign states that emerged/re-emerged from the dissolution of the Soviet Union in 1991. Prior to their independence, they existed as Union Republics, which were the top-level constituents of the Soviet Union. There are 15 post-Soviet states in total: Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine, and Uzbekistan. Each of these countries succeeded their respective Union Republics: the Armenian SSR, the Azerbaijan SSR, the Byelorussian SSR, the Estonian SSR, the Georgian SSR, the Kazakh SSR, the Kirghiz SSR, the Latvian SSR, the Lithuanian SSR, the Moldavian SSR, the Russian SFSR, the Tajik SSR, the Turkmen SSR, the Ukrainian SSR, and the Uzbek SSR. In Russia, the term "near abroad" (Russian: ближнее зарубежье, romanized: bližneye zarubežye) is sometimes used to refer to the post-Soviet states other than Russia.

Following the transition period and cessation of the existence of the Soviet Union, post-Soviet states and the international community de facto and de jure recognized Russia as the only continuator state to the Soviet Union as a whole, rather than to just the Russian SFSR including UN and UNSC membership (see agreements in Succession, continuity and legacy of the Soviet Union). The other post-Soviet states were recognized as successors only to their corresponding Union Republics and to international treaties concluded by the Soviet Union. All 12 post-Soviet states are successors of the Soviet Union, but not continuators.
