Abstract: (Expressions of authenticity in Interwar Romanian Literature): The Romanian interwar poetics of authenticity is characterised by the establishment of an aesthetic and ideological program that involves, on the one hand, the reconfiguration of literature through new forms of writing and, on the other hand, the revitalization of Romanian culture as such. At the same time, interwar Romanian authenticism is characterised by the inclusion and reconfiguration of a series of literary, philosophical and aesthetic influences from Europe (but not only) which will be translated into works of fiction or non-fiction (diaries, studies or treaties) whose aim is to strengthen the sense of identity, both individual and collective. In this paper, a series of prominent examples of Romanian literature (Mircea Eliade, Emil Cioran, Mihail Sebastian, Eugen Ionescu etc.) will be analysed through the lenses of European ideas that have permeated literary and philosophical discourse. Thus, this paper analyse the way in which interwar Romanian discourse (in its variety of forms) was influenced by the circuit of European ideas, which were (re)adapted to the Romanian reality and ethos of the time.
