ENThe paper is an attempt at summarising Józef Mackiewicz’s views concerning the idea of resurrection of the statehood of the Grand Duchy of Lithuania in the interwar period. Its objective is to present the cultural and political foundations for the project in question that were present in deliberations of the so-called ‘Vilnius natives’ but also sources that are basically absent in the domestic thought in the form of a geopolitical profit and loss account that Mackiewicz brings to the fore. The paper also discusses the reasons (the ‘carnival of nationalisms’) due to which the accomplishment of Mackiewicz’s vision, as well as of similar projects implying enhanced integration and cooperation between the states of Eastern Europe, was impossible in the existing political conditions. Keywords: Grand Duchy of Lithuania, geopolitics, nationalism, interwar era, Eastern Europe. [From the publication]
