The collection contains documents relating to the investigation into the assassination of Pyotr Stolypin. Stolypin (1862-1911), after having served as governor of the provinces of Grodno (1902) and Saratov (1903-1906), was appointed in April 1906 as Minister of the Interior and in July 1906 was named chairman of the Council of Ministers in which capacity he served until his assassination. He headed the Russian government at a time of massive protests by workers and peasants against the autocracy. Though firm in suppressing the protests and repressing revolutionary groups, he managed to introduce governmental, economic, and agrarian reforms aimed at improving conditions for farmers. Stolypin's policies irritated not only revolutionaries but many people in positions of power. After surviving several attempts on his life, Stolypin was shot by Dmitrii Bogrov, a leftist radical and agent of Okhrana, in Kiev on 14 September 1911, and died from his wounds four days later. The documents concern the course of the investigation, and the sentencing to death of Bogrov.
