On October 2, 1957, Polish Foreign Minister Adam Rapacki proposed the denuclearization of Central Europe (East and West Germany, Poland, and Czechoslovakia). This collection features materials from 1958 and 1959, the height of discussions concerning the Rapacki Plan, drawn from volumes of Polskie dokumenty dyplomatyczne, a series produced by the Polish Institute of International Affairs. The collection offers insights into Poland’s greatest diplomatic initiative of the late 1950s, one which Warsaw hoped would fundamentally alter the dynamics of European security and carve out a larger role for Poland on the international stage. For an overview of the collection, see Ryan Musto's essay "Polish Perspectives on the Rapacki Plan for the Denuclearization of Central Europe," from Sources & Methods.
