The Vatican and the Eastern Bloc: what the Vatican archives can reveal about Cold War Europe
Five years after the Vatican unsealed its archives on the pontificate of Pope Pius XII, historians are only beginning to uncover the depth of insight they offer into the post-war transformation of Eastern Europe. Far beyond matters of church history, these documents reveal how the Holy See navigated the rise of communism, supported persecuted Catholics behind the Iron Curtain, and responded to the upheaval of millions across the continent.
In March 2020, the Vatican Apostolic Archives opened to consultation a long-awaited treasure trove of documents spanning the neuralgic years of 1939–1958. Named the Vatican Secret Archive until 2019, its extensive holdings are housed in a „bunker” — an underground storage facility in Vatican City. While scholars around the world braced for revelations concerning the Holy See’s wartime diplomacy and the Holocaust, another equally compelling and underexplored story lies within: the history of Eastern Europe during one of its most turbulent transformations from the ruins of World War II to life under state socialism, as seen by the lens of the Vatican.
