The book of Yu. Buranov and V. Khrustalev tells about the tragic fate of the royal family after the February coup. The fall of the Romanov dynasty was the beginning of the path to the death of not only the royal family, but also many grand dukes executed in 1918-1919. Most of the materials cited in this publication were first published by the authors in a book published in 1933-1934 in Germany. But the questions posed by them are not yet answered. The fall of the Romanov dynasty, which began with the abdication of two "crowned" brothers, was the beginning of the path to the death of not only the royal family killed in Yekaterinburg, but also a whole group of grand dukes executed in 1918-1919 in Perm, Alapaevsk, Tashkent and Petrograd.
