This paper offers a theoretical framework for the analysis of the effect of “national narratives” on political discourse in the domestic and international arenas. First, the paper qualifies national narratives as a distinct genre of political discourse, which is driven by the will to expand its influence on states’ discourse within and beyond the political domain. Second, the paper claims that dominant national narratives are being expanded due to their unique structure, which enables their multiplicity in the social arena. This structure is being analyzed in light of the fractal geometry. The idea is that a concise version of national story is being multiplied in variations across people, organizations and places producing a self-similarity structure of discourse. This geometrical structure plays an important role in spreading the core elements of national stories, while at the same time adapting them to the change of conditions, circumstances and contexts. This framework can be used to understand how dominant national narratives are multiplied and echoed in states discourse, and how similarities and dissimilarities between national narratives of different states can affect the communication between states both in elite and peoples’ levels. The framework can also help us understanding the dynamic of changes in national narratives, and their potential effect on national and international political discourse.
