Today, especially after various critical evaluations of mainstream theories of International Relations (IR), it is common place to observe that IR discipline is Eurocentric. Natural outcome of this Eurocentric character of IR discipline has been the privileging of modern identity (and thus, modernity) and the marginalization of different cultures and identities as &quot / others&quot / . This thesis analyzes the relationship between the concepts of modern identity, national interest and difference within the framework of IR theory. The thesis asserts that IR discipline should solve the problem of exclusion of the &quot / other&quot / or suppression of differences since International Relations means first and foremost interaction with the &quot / Other&quot / . In order to solve this contradiction, I argue that IR theory should be deconstructed on the basis of a treatment of differences and heterogeneity. However, criticizing the creation of the &quot / others&quot / necessitates also the critique of modern identity since &quot / heterophobia&quot / is the result of the homogenizing character of European identity. Therefore, a deconstruction of the hegemony of modern identity in IR is the main concern of this thesis. The thesis finally argues that &ldquo / other worlds&rdquo / which leave room for different identities and other &quot / truths&quot / are also possible.

La pénétration des Scandinaves en Russie, qui s’insère dans un vaste mouvement d’échanges qui entre les VIIIe et XIIe siècles fait circuler hommes et biens, apparaît à bien des égards comme un stimulant économique et politique d’envergure dans l’émergence d’organisations politiques et sociales qui aboutirent au développement de centres proto-urbains et du premier État russe. L’objectif de cette étude est donc de s’attacher à travers le traitement des sources historiographiques scandinaves et leur croisement avec les corpus slavon, byzantin et arabo-persan, à l’appréhension des modalités de transport de ces Scandinaves qui empruntèrent la voie de l’Est. Ce traitement nous permettra alors en plus de mesurer la variété et la richesse des contacts et des types de voyages entrepris, de redessiner des itinéraires, et d’appréhender plus en détail de quelle manière l’historiographie envisageait la géographie russe ainsi que le voyage en ces régions. / The penetration of the Scandinavians in Russia, which takes place in this vast movement of exchanges between the eighth and twelfth centuries where men and goods where circulating around Europe, appears in many respects as a political and economic stimulus in the emergence of political and social organizations that led to the development of proto-urban centers and to the creation of the first Russian state. So the aim of this study is through the analyze of the Scandinavian historiography and its crossing with the Slavonic, Byzantine and Arabo-persian corpuses, to focus on the transport modalities of these Scandinavians who took the road to the East. This treatment will allow us to underline the wide variety of contacts and journeys undertaken, and in addition to reconstruct itineraries, and to understand in a better way how historiography dealt with Russian geography and with the journey across those regions as a pattern.
