The subject of this book was the birth and development of the FRG’s energy trade relations with the Soviet Union. It examined how and when the exchange of energy sources and equipment of energy industry between the two states arose and developed, and how and how much it was influenced by domestic and international political dynamics. In this analysis, the supra-state and superpower decision-making levels were considered, as well as the domestic level and the role of national companies. Upon completion of the analysis, it can be confirmed that Germany’s long-standing energy dependence on Russia has its roots in the 1950s, when the first relations were established.
