Abstract: (Culture and Ideology in Interwar Romania: the Role of Books as means of Propaganda) In recent historiography as well as for the general public, the interwar period represents an attractive terrain and a relatively easy scholarly objective. Beyond the systematic analyses of the broad phenomena in that period (society, culture, politics, economy), there are still many under-researched aspects, especially those relating to the micro-levels of everyday life. The country project after the Great Union of 1918 entailed major structural transformations which were internalized in different ways by the society: on the one hand in accordance with legitimate aspirations articulated at community level, on the other as a result of the increasingly deteriorated socio-political climate. This paper aims to investigate a slightly more particular context, which has not often found itself in the middle of historiographical macro-narratives, at least in the Romanian scientific literature. We will try to analyze the scenario of various political instrumentalization attempts of the relationship between ideology and culture and, as a subsidiary, we will highlight the propagandistic potential of written materials, especially those of books. Without aiming at exhaustive interpretations of a complex and multi-layered historical context such as the interwar period, we will insist both on the internal socio-political conditions and on the external geo-political pressures in an attempt to obtain a more veracious radiography of those times.
