Government of the Soviet Union in the context of "USSR"

The Union of Soviet Socialist Republics (USSR), commonly known as the Soviet Union, was a transcontinental country that spanned much of Eurasia from 1922 until it dissolved 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. An overall successor to the Russian Empire, it was nominally organized as a federal union of national republics, the largest and most populous of which was the Russian SFSR. In practice, its government and economy were highly centralized. As a one-party state governed by the Communist Party of the Soviet Union (CPSU), 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 would suffer 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.

The General Secretary of the Central Committee of the Communist Party of the Soviet Union was the leader of the Communist Party of the Soviet Union (CPSU). From 1924 until the country's dissolution in 1991, the officeholder was the recognized leader of the Soviet Union. Prior to Joseph Stalin's accession, the position was not viewed as an important role in Vladimir Lenin's government and previous occupants had been responsible for technical rather than political decisions.

Officially, the General Secretary solely controlled the Communist Party directly. However, since the party had a monopoly on political power, the General Secretary de facto had executive control of the Soviet government. Because of the office's ability to direct both the foreign and domestic policies of the state and preeminence over the Soviet Communist Party, it was the de facto highest office of the Soviet Union.

The 1991 Soviet coup attempt, also known as the August Coup, was a failed attempt by hardliners of the Communist Party of the Soviet Union (CPSU) to forcibly seize control of the country from Mikhail Gorbachev, who was Soviet president and General Secretary of the CPSU at the time. The coup leaders consisted of top military and civilian officials, including Vice President Gennady Yanayev, who together formed the State Committee on the State of Emergency (Russian: ГКЧП, romanized: GKChP). They opposed Gorbachev's reform program, were angry at the loss of control over Eastern European states and fearful of the New Union Treaty, which was on the verge of being signed by the Soviet Union (USSR). The treaty was to decentralize much of the central Soviet government's power and distribute it among its fifteen republics; Boris Yeltsin's demand for more autonomy to the republics opened a window for the plotters to organize the coup.

The GKChP hardliners dispatched KGB agents who detained Gorbachev at his dacha but failed to detain the recently elected president of a newly reconstituted Russia, Boris Yeltsin, who had been both an ally and critic of Gorbachev. The GKChP was poorly organized and met with effective resistance by both Yeltsin and a civilian campaign of anti-authoritarian protesters, mainly in Moscow. The coup collapsed in two days, and Gorbachev returned to office while the plotters all lost their posts. Yeltsin subsequently became the dominant leader and Gorbachev lost much of his influence. The failed coup led to both the immediate collapse of the CPSU and the dissolution of the USSR four months later.

From 1930 to 1952, the government of the Soviet Union, on the orders of Soviet leader Joseph Stalin and under the direction of the NKVD official Lavrentiy Beria, forcibly transferred populations of various groups. These actions may be classified into the following broad categories: deportations of "anti-Soviet" categories of population (often classified as "enemies of the people"), deportations of entire nationalities, labor force transfer, and organized migrations in opposite directions to fill ethnically cleansed territories. Dekulakization marked the first time that an entire class was deported, whereas the deportation of Soviet Koreans in 1937 marked the precedent of a specific ethnic deportation of an entire nationality.

In most cases, their destinations were underpopulated remote areas (see Forced settlements in the Soviet Union). This includes deportations to the Soviet Union of non-Soviet citizens from countries outside the USSR. It has been estimated that, in their entirety, internal forced migrations affected at least 6 million people. Of this total, 1.8 million kulaks were deported in 1930–31, 1.0 million peasants and ethnic minorities in 1932–39, whereas about 3.5 million ethnic minorities were further resettled during 1940–52.

The Soviet bureaucracy played a crucial role in the governance and administration of the USSR. A class of high-ranking party bureaucrats, known as the nomenklatura, formed a de facto elite, wielding immense power over public life.

World War II in the Kingdom of Yugoslavia began on 6 April 1941, when the country was invaded and swiftly conquered by Axis forces and partitioned among Germany, Italy, Hungary, Bulgaria and their client regimes. Shortly after Germany attacked the USSR on 22 June 1941, the communist-led republican Yugoslav Partisans, on orders from Moscow, launched a guerrilla liberation war fighting against the Axis forces and their locally established puppet regimes, including the Axis-allied Independent State of Croatia (NDH) and the Government of National Salvation in the German-occupied territory of Serbia. This was dubbed the National Liberation War and Socialist Revolution in post-war Yugoslav communist historiography. Simultaneously, a multi-side civil war was waged between the Yugoslav communist Partisans, the Serbian royalist Chetniks, the Axis-allied Croatian Ustaše and Home Guard, Serbian Volunteer Corps and State Guard, Slovene Home Guard, as well as Nazi-allied Russian Protective Corps troops.

Both the Yugoslav Partisans and the Chetnik movement initially resisted the Axis invasion. However, after 1941, Chetniks extensively and systematically collaborated with the Italian occupation forces until the Italian capitulation, and thereon also with German and Ustaše forces. The Axis mounted a series of offensives intended to destroy the Partisans, coming close to doing so in the Battles of Neretva and Sutjeska in the spring and summer of 1943.

The Moscow Kremlin, commonly known as just the Kremlin, is a fortified complex in Moscow, Russia. Located in the centre of the country's capital city, the Moscow Kremlin comprises five palaces, four cathedrals, and the enclosing Kremlin Wall along with the Kremlin towers. In the complex is the Grand Kremlin Palace, which was one of the royal residences of the Tsar of Russia, and now is the residence of the president of the Russian Federation. The Moscow Kremlin overlooks the Moskva River to the south, Saint Basil's Cathedral and Red Square to the east, and Alexander Garden to the west.

In the Russian language, kreml' denotes a 'fortress within a city', and there are many historical cities with Kremlin of their own. However, the Moscow Kremlin, the best known, also serves an international-politics metonym that identifies the Government of Russia. During the Cold War (1947–1991), the term The Kremlin meant the Government of the Soviet Union and the term Kremlinology meant the study of the decisions of the Soviet leaders and of Russian and Soviet politics. When open to the public, the Kremlin of Moscow offers supervised tours of the Moscow Kremlin Museums.
