ENLithuanian geographer professor Kazys Pakštas (1893) is notable for his titanic work in different fields of Lithuanian geography. Pakštas has built several visions of the future of Lithuanian nation and its survival in the changing 20th century. All projects of Pakštas were unreal not only in the 1930 n 1940s but also nowadays, except for one, which had a real geopolitical base n the idea of Baltoscandia. The term eBaltoscandiai was first used as a geographical term by the Swedish geographer, professor Sten de Geer in the 1920s. After establishing the Geographical Society in Lithuania in 1933, Pakštas delivered many lectures on the Baltoscandian issue in geographical societies and universities in Stockholm, Oslo, Copenhagen, Helsinki, Tallinn, and Riga in 1933 n 1934. In his views, Pakštas turns to the idea of Baltoscandia as a cultural- geographical, economic, and political-military union. In the article, the most significant characteristics presented by Pakštas that marked the borders of the modern Baltoscandia as a geographical and cultural region will be analyzed.
