Based on archival documents from the Russian State Archive of Contemporary History, the article examines the final period of the journal Problems of Peace and Socialism during the years of Perestroika. By the mid-1980s, the magazine, which had been published in Prague since 1958, had become the only permanent institution of multilateral ideological cooperation within the international communist movement. It functioned as an instrument of the USSR’s soft power, grounded in the ideological and intellectual collaboration of leftist representatives. Attempting to balance Moscow’s interests with the contemporary agenda, by the 1980s the publication had almost completely lost its controversial character. Despite the fact that prominent Marxist scholars and professional journalists contributed to the articles, its materials did not resonate with a broad readership. Attempts to reform the magazine in line with Perestroika ideas were supported by the majority of parties involved in its publication, as evidenced by international meetings held by the editorial board. However, time had been lost, and the journal, which had primarily served as a political instrument in the USSR’s international politics, could not survive the crisis of the world communist movement, the decline of Marxist philosophy, and the collapse of the socialist bloc.
