The 20th century in its most acute form embodied the universal contradiction of all history: the interweaving of heroic and tragic, bright utopianism and bloody pragmatism in the fate of all mankind and the individual. Especially individuals who are bright, strong and free. This type of people includes the hero of the book - the Brazilian revolutionary, "knight of hope" Luis Carlos Prestes (1898-1990). The author fascinatingly talks about the life and struggle of Prestes, relying on rich archival material, including the archive of the Comintern, the experience of personal communication with many Latin American political figures, and wide international historical literature.
