This chapter analyses the effects on political publishing of the party and state authorities’ urgent concerns about the language and form of Soviet propaganda, which emerged very soon after Stalin’s death, lasted throughout the post-Stalin period, and targeted Politizdat as political literature’s main producer. This major drive for more engaging propaganda gave rise, in the 1950s and 1960s, to unprecedented critique of the language of Politizdat’s previous publications, and then to the embrace of biography as the most lively and effective form of propaganda. The creation of the ‘Fiery Revolutionaries’ series initiated a large-scale, long-term experiment with the biography genre and with literary collaboration to revitalize political literature’s popular appeal: it was intended to produce evocative and emotionally involving portraits of a huge gallery of ‘revolutionaries’. The last part of this chapter traces the early, embattled years of the series between its creation in 1964 and its launch in 1968, the same year as the party’s ideological crackdown connected to the intervention in Czechoslovakia.
