ENForeign security policy of Lithuania, like that of other Baltic states, is closely related to the development of her political identity. The paper is an attempt to elucidate the interaction between Lithuania's developing identity, conceptualization of security and foreign security policy. The analysis is based on an assumption that Lithuania’s political reality may be conceptualized as an interplay at least of two competitive discourses: modernity and postmodemity, with each of these reflecting different discursive practices. The modernity discourse conceives the nation and the state as real ontological essences, while the postmodemity discourse grants no pre-discursive existence to the nation and treats the state as merely instrumental in respect of human rights. The article states that contemporary Lithuania, trying to become the center of regional cooperation, is moving towards postmodern liberal democratic state identity' assembling other states by force of the example to be followed. Keywords: Lithuania, modernity', postmodemity, discourse, identity', security', foreign policy.
