A talented engineer and member of the first Social Democratic circle in Russia, a socialite and a skilled underground conspirator, a financial genius of the Bolshevik Party and an organizer of arms supplies for the needs of the revolution - in all his roles, Leonid Krasin achieved brilliant success. Accustomed to taking risks and ready to pay for mistakes, he never became a blind tool in someone’s hands and did not act contrary to his own convictions. That is why in the Bolshevik leadership he always remained a “stranger among his own,” but managed to become a “friend among strangers” in the political establishment of the capitalist world. Leonid Krasin was among the few representatives of the “rogue” state with whom the heads of the Western powers were ready to negotiate and who managed to break through the “cordon sanitaire” around the Land of Soviets. He owes considerable credit for the diplomatic recognition of the RSFSR-USSR and the establishment of trade and economic cooperation with the West. The book, created on a vast array of sources, including archival ones, presents a living literary portrait of Leonid Krasin - a man not only multi-talented, but also able to fully to the extent possible to realize their talents in various spheres of political and public life.
