The study of science popularization in dictatorships, such as Franco’s regime, offers a useful window through which to review definitions of controversial categories such as “popular science” and the “public sphere.” It also adds a new analytical perspective to the historiography of dictatorships and their totalitarian nature. Moreover, studying science popularization in these regimes provides new tools for a critical analysis of key contemporary concepts such as nationalism, internationalism, democracy, and technocracy.

In the late 1940s in Spain, a group of young scholars, most of them newly appointed university lecturers, gained control of Arbor, the promotional journal of the Consejo Superior de Investigaciones Científicas, the institution that General Franco had founded after the Spanish Civil War to organize Spanish science. This group constituted the intellectual core of the more reactionary, Catholic traditionalist faction of Franco’s regime, and they coveted greater political power, in competition with other factions of the regime. Lacking the opportunity (...) to launch an overt political campaign within a dictatorship, the group started a fight for the cultural conquest of Spain. In this cultural struggle for hegemony, journals, magazines, cultural associations, publishing houses, newspapers, and cultural centers became their weapons. By analyzing this faction’s views on and activities within the popularization of science, particularly regarding theories of evolution, this article argues that popular discourse on science played a critical role in the cultural struggle both as a “safe” channel in which to forward their claims and as a tool to gather popular attention through topics of general interest. A covert political campaign was conducted through the popularization of science and this, in turn, fueled the construction of a public sphere for science in a dictatorial context. Scientific popularization became a much-appreciated tool to achieve cultural hegemony and, as such, it also became a central element in constructing and legitimating the ideological foundations of Franco’s regime.
