The monograph is devoted to the history of the integration of the three Baltic states into Euro-Atlantic structures. The main stages of this process are considered - from the formation of a course towards joining two key international institutions of the Western community as the main priority of their foreign policy to the inclusion of Latvia, Lithuania and Estonia in the work of EU bodies and NATO structures as full members of these organizations. The important role played by the support of the neighboring countries of Northern Europe in this process is noted.
