Eastern Europe is a subregion of the European continent. As a largely ambiguous term, it has a wide range of geopolitical, geographical, ethnic, cultural, and socio-economic connotations. Its eastern boundary is marked by the Ural Mountains, whilst its western boundary is defined in various ways. Most definitions include the countries of Belarus, Russia, Ukraine, Moldova, and Romania while less restrictive definitions may also include some or all of the Balkans, the Baltic states, the Caucasus, and the Visegrád group.
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, Council of Europe, 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.
The European Union (EU) has expanded a number of times throughout its history by way of the accession of new member states to the Union. To join the EU, a state needs to fulfil economic and political conditions called the Copenhagen criteria, which require a stable democratic government that respects the rule of law, and its corresponding freedoms and institutions. According to the Maastricht Treaty, each current member state and the European Parliament must agree to any enlargement. The process of enlargement is sometimes referred to as European integration. This term is also used to refer to the intensification of co-operation between EU member states as national governments allow for the gradual harmonisation of national laws.
Europe, the westernmost portion of Eurasia, is often divided into regions and subregions based on geographical, cultural or historical factors. Since there is no universal agreement on Europe's regional composition, the placement of individual countries may vary based on criteria being used. For instance, the Balkans is a distinct geographical region within Europe, but individual countries may alternatively be grouped into South-eastern Europe or Southern Europe.
A raion is a type of administrative unit of several post-Soviet states. The term is used for both a type of subnational entity and a division of a city. The word is from the French rayon, and is commonly translated as "district" in English.
The politics of Europe deals with the continually evolving politics within the continent of Europe. It is a topic far more detailed than other continents due to a number of factors including the long history of nation states in the region as well as the modern day trend towards increased political unity amongst the European states.
Figures for the population of Europe vary according to the particular definition of Europe's boundaries. In 2018, Europe had a total population of over 751 million people. 448 million of that live in the European Union and 110 million live in European Russia, Russia being the most populous country in Europe.
Territorial changes of the Baltic states refers to the redrawing of borders of Lithuania, Latvia and Estonia after 1940. The three republics, formerly autonomous regions within the former Russian Empire and before that of former Polish–Lithuanian Commonwealth and as provinces of the Swedish Empire, gained independence in the aftermath of World War I and the Russian Revolution of 1917. After a two-front independence war fought against both Bolshevist Russian and Baltic German nationalist forces, the countries concluded peace and border treaties with Soviet Russia in 1920. However, with World War II and the occupation and annexation of these republics into the Soviet Union twenty years after their independence, certain territorial changes were made in favour of the Russian SFSR. This has been the source of political tensions after they regained their independence with the dissolution of the Soviet Union. Some of the disputes remain unresolved.
The post-Soviet states, also referred to as the former Soviet Union (FSU) 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" is sometimes used to refer to the post-Soviet states other than Russia.
Russians in the Baltic states is a broadly defined subgroup of the Russian diaspora who self-identify as ethnic Russians, or are citizens of Russia, and live in one of the three independent countries — Estonia, Latvia, and Lithuania — primarily the consequences of the USSR's forced population transfers during occupation. As of 2023, there were approximately 887,000 ethnic Russians in the three countries, having declined from ca 1.7 million in 1989, the year of the last census during the 1944–1991 Soviet occupation of the three Baltic countries.
The Adapted Conventional Armed Forces in Europe Treaty is a post–Cold War adaptation of the Treaty on Conventional Armed Forces in Europe (CFE), signed on November 19, 1999, during the Organization for Security and Co-operation in Europe's (OSCE) 1999 Istanbul summit. The main difference with the earlier treaty is that the troop ceilings on a bloc-to-bloc basis would be replaced with a system of national and territorial ceilings. Furthermore, the adapted treaty would provide for more inspections and new mechanisms designed to reinforce States Parties’ ability to grant or withhold consent for the stationing of foreign forces on their territory.
The Community for Democracy and Rights of Nations, also commonly and colloquially known as the Commonwealth of Unrecognized States, rarely as CIS-2, is an international organization in Eastern Europe and the South Caucasus of three breakaway states in the territory of the former Soviet Union, all of which have limited to no recognition from the international community.
The New Union Treaty was a draft treaty that would have replaced the 1922 Treaty on the Creation of the Union of Soviet Socialist Republics (USSR) to salvage and reform the USSR. A ceremony of the Russian SFSR signing the treaty was scheduled for 20 August 1991 but was prevented by the August Coup a day earlier.
The three Baltic countries, or the Baltic states – Estonia, Latvia, and Lithuania – are held to have continued as independent states under international law while under Soviet occupation from 1940 to 1991, as well as during the German occupation in 1941–1944/1945. The prevailing opinion accepts the Baltic thesis that the Soviet occupation was illegal, and all actions of the Soviet Union related to the occupation are regarded as contrary to international law in general and to the bilateral treaties between the USSR and the three Baltic countries in particular.
Russian-occupied territories in Georgia are areas of Georgia that have been occupied by Russia since the Russo-Georgian War in 2008. They consist of the regions of the Autonomous Republic of Abkhazia and the former South Ossetian Autonomous Region of Soviet Georgia, whose status is a matter of international dispute.
Cooperation between China and Central and Eastern European Countries is an initiative by the Chinese Ministry of Foreign Affairs to promote business and investment relations between China and 14 countries of Central and Eastern Europe : Albania, Bosnia and Herzegovina, Bulgaria, Croatia, the Czech Republic, Greece, Hungary, Montenegro, North Macedonia, Poland, Romania, Serbia, Slovakia, and Slovenia. Prior to their 2022 withdrawal, Estonia, Latvia, and Lithuania were members of the initiative.
Since the dissolution of the Soviet Union in 1991, Russia has been involved in territorial disputes with a number of other post-Soviet states. These disputes are primarily an aspect of the post-Soviet conflicts, and have led to some countries losing parts of their sovereign territory to what a large portion of the international community designates as a Russian military occupation. As such, these lands are commonly described as Russian-occupied territories, regardless of what their status is in Russian law. The term is applied to Georgia, Moldova, and Ukraine.
The road signs in the post-Soviet states Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan are largely similar to the Soviet road sign system, as these countries were part of the Soviet Union until its dissolution in 1991. However, in some countries of the former USSR, some road signs may look different from the Soviet ones. The Soviet Union was a signatory to the 1968 Vienna Convention on Road Signs and Signals. After the dissolution of the Soviet Union in 1991, most of the post-Soviet states adopted their own road sign standards. Many of them use road sign systems that inherited the road sign system used in the Soviet Union before 1991, but with some modifications, except for Estonia and Latvia that use completely different road sign systems. Estonia and Latvia have their own road sign systems, which are very different in design from the Soviet one. Modern road signs in Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan comply with the Vienna Convention on Road Signs and Signals as well as most European countries. Of the 15 former post-Soviet states, only Belarus, Russia and Ukraine have signed and ratified the Vienna Convention on Road Signs and Signals on behalf of the Soviet socialist republics. These 3 countries have ratified this convention on June 18, 1974.
