The book is devoted to one of the insufficiently studied problems of the political history of the Russian diaspora - the post-revolutionary movements and organizations of the first wave of emigration. The history of the emergence and development of post-revolutionary organizations and their ideology is considered, the problem of developing by post-revolutionary thinkers the concept of a "third way" for the development of Russia, alternative to liberalism and communism, stands out. The scientific study of this topic at such a level and in such a volume is carried out for the first time in Russian historiography.
