The celebrations of the millennium of Christianity and the beginnings of the Polish state, as a result of deep political conflict, could not be organized jointly by the State and Church. Centuries of belonging to the Christian community were opposed to the twentieth-century history of socialist Poland, acknowledged in propaganda material as “the crowning of all the nation’s historical development.” It was no different in Warmia and Masuria, where the presentation and interpretation of Polish heritage (concerning the Polishness of these lands and their general development after 1945), aimed to distance society from the Church, including participation in the millennium celebrations, in the case of Olsztyn province, organised in Frombork, with the participation of Cardinal Stefan Wyszyński. The aim was to counter attacks on the Church and the clergy, and especially the propaganda campaign related to the post-war period. The competing, secular celebration of the Millennium of Poland was organized in Lidzbark Warmiński, with the participation of the highest, partyadministrative provincial authorities.
