Warsaw Pact in the context of "Enlargement of NATO"

Romania is a country located at the crossroads of Central, Eastern and Southeast Europe. It borders Ukraine to the north and east, Hungary to the west, Serbia to the southwest, Bulgaria to the south, Moldova to the east, and the Black Sea to the southeast. It has a mainly continental climate, and an area of 238,397 km (92,046 sq mi) with a population of 19 million people. Romania is the twelfth-largest country in Europe and the sixth-most populous member state of the European Union. Europe's second-longest river, the Danube, empties into the Danube Delta in the southeast of the country. The Carpathian Mountains cross Romania from the north to the southwest and include Moldoveanu Peak, at an altitude of 2,544 m (8,346 ft). Bucharest is the country's capital, largest urban area, and financial centre. Other major urban areas include Cluj-Napoca, Timișoara, Iași, Constanța and Brașov.

Settlement in the territory of modern Romania began in the Lower Paleolithic, later becoming the Dacian Kingdom before Roman conquest and Romanisation. The modern Romanian state was formed in 1859 with the unification of Moldavia and Wallachia under Alexandru Ioan Cuza, becoming the Kingdom of Romania in 1881 under Carol I of Romania. Romania gained independence from the Ottoman Empire in 1877, formalised by the Treaty of Berlin. After World War I, Transylvania, Banat, Bukovina, and Bessarabia joined the Old Kingdom, forming Greater Romania, which reached its largest territorial extent. In 1940, under Axis pressure, Romania lost territories to Hungary, Bulgaria, and the Soviet Union. Following the 1944 Romanian coup d'état, Romania switched sides to join the Allies. After World War II, it regained Northern Transylvania through the Paris Peace Treaties. Under Soviet occupation, King Michael I was forced to abdicate, and Romania became a socialist republic and Warsaw Pact member. After the uniquely violent Romanian revolution in December 1989, Romania began a transition to liberal democracy and a market economy.

The Cold War was a period of global geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.

After the end of the Second World War in 1945, during which the US and USSR had been allies, the USSR installed satellite governments in its occupied territories in Eastern Europe and North Korea by 1949, resulting in the political division of Europe (and Germany) by an "Iron Curtain". The USSR tested its first nuclear weapon in 1949, four years after their use by the US on Hiroshima and Nagasaki, and allied with the People's Republic of China, founded in 1949. The US declared the Truman Doctrine of "containment" of communism in 1947, launched the Marshall Plan in 1948 to assist Western Europe's economic recovery, and founded the NATO military alliance in 1949 (matched by the Soviet-led Warsaw Pact in 1955). The Berlin Blockade of 1948 to 1949 was an early confrontation, as was the Korean War of 1950 to 1953, which ended in a stalemate.

The post–Cold War era is a period of history that follows the end of the Cold War, which represents history after the dissolution of the Soviet Union in December 1991. This period saw many former Soviet republics become sovereign states, as well as the introduction of market economies in Eastern Europe. This period also marked the United States becoming the world's sole superpower.

Relative to the Cold War, the period is characterized by stabilization and disarmament. Both the United States and Russia significantly reduced their nuclear stockpiles. Much of the former Eastern Bloc became democratic and was integrated into the world economy. In the first two decades of the period, NATO underwent three enlargements, and France reintegrated into the NATO command. Russia formed the Collective Security Treaty Organization to replace the dissolved Warsaw Pact, established a strategic partnership with China and several other countries, and entered the Shanghai Cooperation Organisation and BRICS alongside China, which is a rising power. Reacting to the rise of China, the United States began a gradual rebalancing of strategic forces to the Asia–Pacific region and out of Europe.

The term Third World arose during the Cold War to define countries that remained non-aligned with either NATO or the Warsaw Pact. The United States, Canada, Japan, South Korea, the Southern Cone, Western European countries and other allies represented the "First World", while the Soviet Union, China, Cuba, North Korea, Vietnam, and their allies represented the "Second World". This terminology provided a way of broadly categorizing the nations of the Earth into three groups based on political divisions. Due to the complex history of evolving meanings and contexts, there is no clear or agreed-upon definition of the Third World. Strictly speaking, "Third World" was a political, rather than economic, grouping.

Since most Third World countries were economically poor and non-industrialized, it became a stereotype to refer to developing countries as "third-world." In political discourse, the term Third World was often associated with being underdeveloped. China was labeled "Third World" for several decades in the 20th century before its robust development of the 21st century. Some countries in the Eastern Bloc, such as Cuba, were often regarded as Third World. The Third World was normally seen to include many countries with colonial pasts in Africa, Latin America, Oceania, and Asia. It was also sometimes taken as synonymous with countries in the Non-Aligned Movement. In the dependency theory of thinkers like Raúl Prebisch, Walter Rodney, Theotônio dos Santos, and others, the Third World has also been connected to the world-systemic economic division as "periphery" countries dominated by the countries comprising the economic "core".

Central and Eastern Europe is a geopolitical term encompassing the countries in Northeast Europe (primarily the Baltics), Central Europe (primarily the Visegrád Group), Eastern Europe, and Southeast Europe (primarily the Balkans), usually meaning former communist states from the Eastern Bloc and Warsaw Pact in Europe, as well as from former Yugoslavia. Scholarly literature often uses the abbreviations CEE or CEEC for this term. The Organisation for Economic Co-operation and Development (OECD) also uses the term "Central and Eastern European Countries" (CEECs) for a group comprising some of these countries. This term is sometimes used as an alternative to the term "Eastern Europe," for more neutral grouping.

The Socialist Republic of Romania (Romanian: Republica Socialistă România, RSR) was a communist state that existed officially in Romania from 1947 to 1989 (see Revolutions of 1989). From 1947 to 1965, the state was known as the Romanian People's Republic (Republica Populară Romînă, RPR). The country was an Eastern Bloc state and a member of the Warsaw Pact with a dominant role for the Romanian Communist Party enshrined in its constitutions. Geographically, RSR was bordered by the Black Sea to the east, the Soviet Union (via the Ukrainian and Moldavian SSRs) to the north and east, Hungary and Yugoslavia (via SR Serbia) to the west, and Bulgaria to the south.

As World War II ended, Romania, a former Axis member which had overthrown their pro-Axis government, was occupied by the Soviet Union as the sole representative of the Allies. On 6 March 1945, after mass demonstrations by communist sympathizers and political pressure from the Soviet representative of the Allied Control Commission, a new pro-Soviet government that included members of the previously outlawed Romanian Workers' Party was installed. Gradually, more members of the Workers' Party and communist-aligned parties gained control of the administration and pre-war political leaders were steadily eliminated from political life. In December 1947, King Michael I was forced to abdicate and the People's Republic of Romania was declared.

The Romanian revolution (Romanian: Revoluția română) was a period of violent civil unrest in Romania during December 1989 as a part of the revolutions of 1989 that occurred in several countries around the world, primarily within the Eastern Bloc. The Romanian revolution started in the city of Timișoara and soon spread throughout the country, ultimately culminating in the drumhead trial and execution of longtime Romanian Communist Party (PCR) General Secretary Nicolae Ceaușescu and his wife Elena, and the end of 42 years of Communist rule in Romania. It was also the last removal of a Marxist–Leninist government in a Warsaw Pact country during the events of 1989, and the only one that violently overthrew a country's leadership and executed its leader; according to estimates, over one thousand people died and thousands more were injured.

Following World War II, Romania found itself inside the Soviet sphere of influence, with Communist rule officially declared in 1947. In April 1964, when Romania published a general policy paper worked out under Gheorghe Gheorghiu-Dej's instructions, the country was well on its way of carefully breaking away from Soviet control. Nicolae Ceaușescu became the country's leader the following year. Under his rule, Romania experienced a brief waning of internal repression that led to a positive image both at home and in the West. However, repression again intensified by the 1970s. Amid tensions in the late 1980s, early protests occurred in the city of Timișoara in mid-December on the part of the Hungarian minority in response to an attempt by the government to evict Hungarian Reformed Church pastor László Tőkés. In response, Romanians sought the deposition of Ceaușescu and a change in government in light of similar recent events in neighbouring nations. The country's ubiquitous secret police force, the Securitate, which was both one of the largest in the Eastern Bloc and for decades had been the main suppressor of popular dissent, frequently and violently quashing political disagreement, ultimately proved incapable of stopping the looming, and then highly fatal and successful revolt.

The 2014 Winter Olympics, officially called the XXII Olympic Winter Games (Russian: XXII Олимпийские зимние игры, romanised: XXII Olimpiyskiye zimniye igry) and commonly known as Sochi 2014 (Сочи 2014), were an international winter multi-sport event that was held from 7 to 23 February 2014 in Sochi, Russia. Opening rounds in certain events were held on 6 February 2014, the day before the opening ceremony.

These were the first Olympic Games under the International Olympic Committee (IOC) presidency of Thomas Bach. Both the Olympics and Paralympics were organised by the Sochi Organizing Committee (SOOC). Sochi was selected as the host city on 5 July 2007, during the 119th IOC Session held in Guatemala City. It was the first Olympics to be held in a CIS state and former Warsaw Pact state after the Revolutions of 1989 and the collapse of the Soviet Union in 1991. The Russian Soviet Federative Socialist Republic previously hosted the Summer Olympics in 1980.
