The **National Alliance of Russian Solidarists** (abbr. **NTS**; [Russian](https://en.wikipedia.org/wiki/Russian_language): Народно-трудовой союз российских солидаристов (НТС), [romanized](https://en.wikipedia.org/wiki/Romanization_of_Russian): *Narodno-trudovoy soyuz rossiyskikh solidaristov*, [lit.](https://en.wikipedia.org/wiki/Literal_translation) 'People's Labor Union of Russian Solidarists') is a Russian anticommunist organization founded in 1930 by a group of young Russian [anticommunist](https://en.wikipedia.org/wiki/Anticommunist) [White émigrés](https://en.wikipedia.org/wiki/White_%C3%A9migr%C3%A9) in [Belgrade](https://en.wikipedia.org/wiki/Belgrade), [Serbia](https://en.wikipedia.org/wiki/Serbia) (then part of the [Kingdom of Yugoslavia](https://en.wikipedia.org/wiki/Kingdom_of_Yugoslavia)).

The organization formed in response to the older generation of Russian [émigrés](https://en.wikipedia.org/wiki/White_%C3%A9migr%C3%A9) (veterans of the [White movement](https://en.wikipedia.org/wiki/White_movement)) whom NTS-members perceived as stagnant and resigned to their loss in the [Russian Civil War](https://en.wikipedia.org/wiki/Russian_Civil_War) of 1917–1923. The young people who founded NTS decided to take an active role in fighting against [communism](https://en.wikipedia.org/wiki/Communism): by studying the newly emerging [Soviet culture](https://en.wikipedia.org/wiki/Culture_of_the_Soviet_Union) and the psyche of persons living in the [Soviet Union](https://en.wikipedia.org/wiki/Soviet_Union), and by developing a political program based on the concept of [solidarism](https://en.wikipedia.org/wiki/Corporatism#Corporate_solidarism). The organisation worked closely with the Nazis during the occupation of Russia, moving their headquarters to Berlin and acting as local administrators and collaborators.
