In December 1981, when Poland’s communist authorities declared martial law and arrested thousands of Solidarity activists, two distinguished Polish diplomats protested by renouncing their allegiance to the Moscow-dominated government in Warsaw and seeking political asylum in the United States. One was Romuald Spasowski, ambassador to the United States; the other was Zdzisław Rurarz, Poland’s ambassador to Japan. The Spasowski papers came to Hoover nearly two decades ago, the Rurarz archives only now. That both collections ended up here and not in Poland or elsewhere reflects the donors’ confidence in the strength and the credibility of the Hoover Archives, which are already home to the largest and most comprehensive holdings on modern Poland outside Poland.
