Soviet Union
The Union of Soviet Socialist Republics, also known as the Soviet Union, was a transcontinental country that spanned much of Eurasia from 1922 until its dissolution in 1991. During its existence, it was the largest country by area, extending across eleven time zones and sharing borders with twelve countries, and the third-most populous country. A diverse multinational state, it was organized as a federal union of national republics, the largest and most populous being the Russian Soviet Federative Socialist Republic. In practice, its government and economy were highly centralized. As a one-party state governed by the Communist Party of the Soviet Union, it was the flagship communist state. Its capital and largest city was Moscow.
The Soviet Union's roots lay in the October Revolution of 1917. The new government, led by Vladimir Lenin, established the Russian SFSR, the world's first constitutionally communist state. The revolution was not accepted by all within the Russian Republic, resulting in the Russian Civil War. The Russian SFSR and its subordinate republics were merged into the Soviet Union in 1922. Following Lenin's death in 1924, Joseph Stalin came to power, inaugurating rapid industrialization and forced collectivization that led to significant economic growth but contributed to a famine between 1930 and 1933 that killed millions. The Soviet forced labour camp system of the Gulag was expanded. During the late 1930s, Stalin's government conducted the Great Purge to remove opponents, resulting in large scale deportations, arrests, and show trials accompanied by public fear. Having failed to build an anti-Nazi coalition in Europe, the Soviet Union signed a non-aggression pact with Nazi Germany in 1939. Despite this, in 1941 Germany invaded the Soviet Union in the largest land invasion in history, opening the Eastern Front of World War II. The Soviets played a decisive role in defeating the Axis powers while liberating much of Central and Eastern Europe. However, they suffered an estimated 27 million casualties, which accounted for most losses among the victorious Allies. In the aftermath of the war, the Soviet Union consolidated the territory occupied by the Red Army, forming satellite states, and undertook rapid economic development which cemented its status as a superpower.
Geopolitical tensions with the United States led to the Cold War. The American-led Western Bloc coalesced into NATO in 1949, prompting the Soviet Union to form its own military alliance, the Warsaw Pact, in 1955. Neither side engaged in direct military confrontation, and instead fought on an ideological basis and through proxy wars. In 1953, following Stalin's death, the Soviet Union undertook a campaign of de-Stalinization under Nikita Khrushchev, which saw reversals and rejections of Stalinist policies. This campaign caused ideological tensions with the PRC led by Mao Zedong, culminating in the acrimonious Sino-Soviet split. During the 1950s, the Soviet Union expanded its efforts in space exploration and took a lead in the Space Race with the first artificial satellite, the first human spaceflight, the first space station, and the first probe to land on another planet. In 1985, the last Soviet leader, Mikhail Gorbachev, sought to reform the country through his policies of glasnost and perestroika. In 1989, various countries of the Warsaw Pact overthrew their Soviet-backed regimes, leading to the fall of the Eastern Bloc. A major wave of nationalist and separatist movements erupted across the Soviet Union, primarily in Azerbaijan, Georgia and the Baltic states. In 1991, amid efforts to preserve the country as a renewed federation, an attempted coup against Gorbachev by hardline communists prompted the largest republics—Ukraine, Russia, and Belarus—to secede. On 26 December, Gorbachev officially recognized the dissolution of the Soviet Union. Boris Yeltsin, the leader of the Russian SFSR, oversaw its reconstitution into the Russian Federation, which became the Soviet Union's successor state; all other republics emerged as fully independent post-Soviet states. The Commonwealth of Independent States was formed in the aftermath of the disastrous Soviet collapse, although the Baltics would never join.
During its existence, the Soviet Union was one of the most advanced industrial states, producing many significant social and technological achievements and innovations. It had the world's second-largest economy and largest standing military. As a nuclear state, it wielded the largest arsenal of nuclear weapons in the world. As an Allied nation, it was a founding member of the United Nations as well as one of the five permanent members of the United Nations Security Council. Before its dissolution, the Soviet Union was one of the world's two superpowers through its hegemony in Eastern Europe and Asia, global diplomacy, ideological influence, military might, economic strengths, and scientific accomplishments.
Etymology
The word soviet is derived from the Russian word , meaning 'council', 'assembly', 'advice', ultimately deriving from the proto-Slavic verbal stem of vět-iti, related to Slavic věst, English wise. The word sovietnik means 'councillor'. Some organizations in Russian history were called council. In the Russian Empire, the State Council, which functioned from 1810 to 1917, was referred to as a Council of Ministers.The soviets as workers' councils first appeared during the 1905 Russian Revolution. Although they were quickly suppressed by the Imperial army, after the February Revolution of 1917, workers' and soldiers' soviets emerged throughout the country and shared power with the Russian Provisional Government. The Bolsheviks, led by Vladimir Lenin, demanded that all power be transferred to the soviets, and gained support from the workers and soldiers. After the October Revolution, in which they seized power from the Provisional Government in the name of the soviets, Lenin proclaimed the formation of the Russian Socialist Federal Soviet Republic.
During the Georgian Affair of 1922, Lenin called for the Russian SFSR and other national soviet republics to form a greater union which he initially named as the Union of Soviet Republics of Europe and Asia. Joseph Stalin initially resisted Lenin's proposal but ultimately accepted it, and with Lenin's agreement he changed the name to the Union of Soviet Socialist Republics, although all republics began as socialist soviet and did not change to the other order until 1936. In addition, in the regional languages of several republics, the word council or conciliar in the respective language was only quite late changed to an adaptation of the Russian soviet and never in others, e.g. Ukrainian SSR.
СССР is the abbreviation of the Russian-language cognate of USSR, as written in Cyrillic letters. The soviets used this abbreviation so frequently that audiences worldwide became familiar with its meaning. After this, the most common Russian initialization is Союз ССР which essentially translates to Union of SSRs in English. In addition, the Russian short form name Советский Союз is also commonly used, but only in its unabbreviated form. Since the start of the Great Patriotic War at the latest, abbreviating the Russian name of the Soviet Union as СС has been taboo, the reason being that СС as a Russian Cyrillic abbreviation is associated with the infamous Schutzstaffel of Nazi Germany, as SS is in English.
In English-language media, the state was referred to as the Soviet Union or the USSR. The Russian SFSR dominated the Soviet Union to such an extent that, for most of the Soviet Union's existence, it was colloquially, but incorrectly, referred to as Russia.
History
The history of the Soviet Union began with the ideals of the Bolshevik Revolution and ended in dissolution amid economic collapse and political disintegration. Established in 1922 following the Russian Civil War, the Soviet Union became a one-party state under the Communist Party. Its early years under Lenin were marked by the implementation of socialist policies and the New Economic Policy, which allowed for market-oriented reforms.The rise of Joseph Stalin in the late 1920s ushered in an era of intense centralization and totalitarianism. Stalin's rule was characterized by the forced collectivization of agriculture, rapid industrialization, and the Great Purge, which eliminated perceived enemies of the state. The Soviet Union, one of the Big Four Allied powers alongside the United States, the United Kingdom, and China, played a crucial role in the Allied victory in World War II. It paid a tremendous human cost with millions of Soviet citizens dying in the conflict.
The Soviet Union emerged as one of the world's two superpowers, leading the Eastern Bloc in opposition to the Western Bloc during the Cold War. This period saw the USSR engage in an arms race, the Space Race, and proxy wars around the globe. The post-Stalin leadership, particularly under Nikita Khrushchev, initiated a de-Stalinization process, leading to a period of liberalization and relative openness known as the Khrushchev Thaw. However, the subsequent era under Leonid Brezhnev, sometimes referred to as the Era of Stagnation, was marked by economic decline, political corruption, and a rigid gerontocracy. Despite efforts to maintain the Soviet Union's superpower status, the economy struggled due to its centralized nature, technological backwardness, and inefficiencies. The vast military expenditures and burdens of maintaining the Eastern Bloc further strained the Soviet economy.
In the 1980s, Mikhail Gorbachev's policies of glasnost and perestroika aimed to revitalize the Soviet system but instead accelerated its unraveling. Nationalist movements gained momentum across the Soviet republics and the control of the Communist Party weakened. The failed coup attempt in August 1991 against Gorbachev by hardline communists hastened the end of the Soviet Union, which formally dissolved on 26 December 1991, ending nearly seven decades of Soviet rule.
