General M.K. Dieterichs (1874–1937) was an active participant in the Russo-Japanese War and the First World War, as well as many events of the Russian Civil War. In the summer of 1922, at the Zemsky Council in Vladivostok, Diterichs was elected ruler of Primorye and governor of the Zemsky army. Dieterichs played an important role in the investigation of the crime committed in Yekaterinburg on July 17, 1918 - the murder of the Royal Family. His book about this atrocity became a bibliographic rarity during the author’s lifetime. Dieterichs was the first to come to the conclusion that the regicide occurred due to a deep split in government and society, a lack of a sense of statehood and patriotism among the so-called public, the “Western boyars.” All this led to February and October 1917, and then to the regicide. But the real tragedy of the dynasty, according to the author, was that the Russian people themselves refused allegiance to it, breaking the kiss of the cross given at the Zemsky Sobor of 1613.
