Hoover’s Polish archival collections, the largest and most comprehensive holdings on twentieth-century Poland outside Poland, now include the papers of another key figure in the process of transforming of the country from a Soviet satellite ruled by an authoritarian communist regime into an independent democratic republic. Stanisław Ciosek’s papers and photographs document mostly the years 1980–96, his tenure as minister of labor as well as a Central Committee and Politburo member, endeavoring to contain the rise of the Solidarity trade union movement, followed by nearly seven years of work for his erstwhile adversaries as the new Poland’s ambassador to Moscow.
