The Russian Empire is intensively preparing for an already close world war. At the outfitting walls of the shipyards are the latest battleships, the army is training at an accelerated pace before future battles, but most importantly, Empress Olga managed to form a new edition of the Entente, based not on a confusion of bilateral agreements, but on one multilateral agreement, which clearly stipulates the areas of responsibility of the parties. This time, the Russian army will act strictly in accordance with pre-war plans and based solely on its own interests, and the issue of the Black Sea Straits should be resolved long before the guns rumble on the European fields. At the same time, a clear and harmonious plan has already been grossly violated at least once and so far no one knows whether this violation will turn out to be good or not. Leaving the forced resignation, the Bulgarian prince Ferdinand, renounces not only for himself, but also for all his children, and for the Bulgarian throne, after some perturbations, they choose the husband of the Serbian princess Elena (almost queen) Mikhail Alexandrovich Romanov, part-time beloved brother of the Russian empress. This decision of the Bulgarian deputies-electors is tantamount to a bucket of kerosene generously poured on the embers of Balkan politics.
