One of the key problems of the state historical policy in the Kaliningrad region during the Soviet period was related to the attitude to the local pre-war historical and cultural heritage, it was partly the memory of the life and activities of the outstanding philosopher and educator Immanuel Kant. The purpose of this article is to identify the prerequisites, factors and stages of integration of Kant’s name and image into the regional culture of memory and commemorative activity. The scientific novelty of the study is determined by the fact that the commemoration of the philosopher is first considered throughout the Soviet period of the region’s history. In the first post-war decade, the key condition for the formation of Kant’s commemoration traditions in the young Soviet region was ensured, that is, his tomb was preserved and taken under state protection in the mid-1950s. It became a place of attraction for Kaliningrad residents and guests of the city. In the 1960s–1970s, the philosopher’s grave was included in excursion routes and tourist guides, respect for his memory was used as an argument in the propaganda system, a tradition of scientific study of Kant’s heritage was formed in the region, and Kaliningrad State University became a center of such research. Under strict restrictions on the study and popularization of pre-war history, Kantian topics were perceived by a part of local intelligentsia as an allowed opportunity to share the “secrets” of the German past of the Kaliningrad land. At the same time, the position of regional authorities was characterized by contradictions, and initiatives to commemorate the philosopher were repeatedly met with resistance instigated by the regional committee of the CPSU. In the years of perestroika Kant’s image was perceived as a “bridge” connecting epochs and cultures. The work on the preparation of restoring the monument to the philosopher began, the plans of the regional branch of the Soviet Culture Fund included a “Kantian” programme of events, Kant became a character in the first popular narratives about the prewar history of the region. The process of integration of the “outstanding ‘fellow countryman’”, “Kaliningrad philosopher” into the regional culture by the end of the Soviet period was considerably accelerated.
