The article is devoted to the book of the famous St. Petersburg historian A. B. Nikolaev, the subject of whose research was the work of the State Conference in Moscow, held in August 1917, on the eve of the speech of General L. G. Kornilov. For the first time in historiography, the work of this political forum is covered in such detail and thoroughly. The author comes to the conclusion that the State Conference was conceived by A.F. Kerensky and the Provisional Government as an attempt to develop a national consensus during its work. The results of the State Conference were contradictory, demonstrating the instability of the position of both A.F. Kerensky himself and the Provisional Government as a whole.
