The armed uprising of 1932 is the largest in the history of Mongolia of the twentieth century. What caused it? On whom did the rebels rely, and who supplied them? Why was the uprising crushed? The study of previously unknown Russian archives in combination with previously published and unpublished Mongolian materials made it possible to answer these questions. The book gives a reconstruction of the uprising and the measures to suppress it. Unique photographs are given, as well as copies of some Soviet archival documents.
