Abstract

In order to realize the meaning of the major historical events and the essence of contemporary initiatives in the context of the Baltic Sea Region (BSR), this paper identifies the following issues: – efforts of the Polish diplomacy to create a stable form of political and military cooperation in the subregion of the Baltic Sea and Eastern European region in the interwar period; – not a successful attempt to integrate The Triple Baltic Entente by the Baltic States (Lithuania, Latvia and Estonia); – presentation of the factors that determine the effective and successful partnerships emerging in the BSR in the early twenty-first century, with particular emphasis on the initiatives taken by Poland and Baltic states; – efforts of Poland and the Baltic states to jointly cope with the formation of „unity of brotherhood” in BSR. Last but least, the article presents an analysis of the Polish foreign policy at the beginning of the century and the general directives for the newly established Baltic countries (Lithuania, Latvia and Estonia).
