ENWith the formation of the ideological basis of the Lithuanian national movement in the second half of the 19th century, a fairly great attention was paid to the legal and cultural interpretation of the GDL heritage. In personal correspondence on the pages of "Aušra" and "Varpas", Lithuanian figures of culture were lively discussing the benefit and harm of the GDL heritage for Lithuanian national culture. Besides, there was a tendency to „Lithuanize" that heritage, denying a positive role of polish culture. The ideologists of the Lithuanian national movement, being aware of the importance of the GDL self-independence, accentuated the right of Lithuanians as a historical nation to a political existence, and in the interpretations of cultural heritage dominated a cultural model formulated by S. Daukantas. The reception of the GDL heritage was perceived in a very practical way - as an argument, which confirmed the primary Lithuanian basis of the GDL and culture. Later, it was variously modified, depending on the political circumstances. The judgement of the GDL cultural heritage was similar to the outlook of the Middle and East European nations - Hungarians, Czechs, Croatians - on its early, multinational feudal states. Lithuanian specialists in literature and linguists seem to have greatly contributed to the analysis of the Lithuanian forms of the GDL cultural heritage, as if fixing the principle formulated by the followers of "Aušra" to investigate ethnic Lithuanian core. In Soviet times, the GDL history would often serve for the illustration of „international friendship". At present, an attempt is made to comprehend the development of Lithuanian cultural model in the context of multicultural and continuously emerging new alternatives. The problems of the GDL cultural heritage are attempted to be analyzed in a similar way.
