The post-Soviet states, also commonly known as the former Soviet Union (FSU) or former Soviet republics, are the 15 independent states that seceded from the Union of Soviet Socialist Republics in its dissolution in December 1991. They were also referred to as the Newly Independent States (NIS), notwithstanding that the Baltic states consider themselves to have resumed their pre–World War II sovereignty upon their separation from the Soviet Union.

The 15 post-Soviet states are typically divided into the following five groupings. Each of these regions has its own common set of traits, owing not only to geographic and cultural factors but also to that region's history in relation to Russia. In addition, there are a number of de facto independent, but internationally unrecognized states (see the section Separatist conflicts below).

The dissolution of the Soviet Union took place as a result and against the backdrop of general economic stagnation, even regression. As the Gosplan, which had set up production chains to cross SSR lines, broke down, the inter-republic economic connections were also disrupted, leading to even more serious breakdown of the post-Soviet economies.

The Soviet Union (Russian: Советский Союз, tr. Sovetsky Soyuz), officially the Union of Soviet Socialist Republics (USSR; Russian: Сою́з Сове́тских Социалисти́ческих Респу́блик, tr. Soyuz Sovetskikh Sotsialisticheskikh Respublik; IPA: [sɐˈjus sɐˈvʲetskʲɪx sətsɨəlʲɪˈstʲitɕɪskʲɪx rʲɪsˈpublʲɪk] ( listen); abbreviated СССР, SSSR), was a constitutionally socialist state that existed in Eurasia between 1922 and 1991.

The Soviet Union was a single-party state ruled by the Communist Party from its foundation until 1990. A union of 15 subnational Soviet republics, the Soviet state was structured under a highly centralized government and economy.

The Russian Revolution of 1917 caused the downfall of the Russian Empire. Following the Russian Revolution, there was a struggle for power between the Bolshevik party, led by Vladimir Lenin, and the anti-communist White movement. In December 1922, the Bolsheviks won the civil war, and the Soviet Union was formed with the merger of the Russian Soviet Federative Socialist Republic, the Transcaucasian Socialist Federative Soviet Republic, the Ukrainian Soviet Socialist Republic and the Byelorussian Soviet Socialist Republic.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.
