The chronological framework of the monograph is much wider than the period indicated in the title, when many Russian people realized the perniciousness of the protracted political and internecine struggle and began to unite to expel the interventionists and jointly decide the fate of the tsarist throne. The Appendix to the work contains biographies of the most prominent participants in those events and publishes the most important archival documents related to the Zemsky Sobor. For historians, teachers, students.
