But there is one significant problem among the northern neighbours of Poland - chauvinism, which had a chance to be reborned after the fall of the Soviet Union. Hidden over the years, its biggest enemy found in Polishness and now is the main unifying factor for Lithuanians. They have Polishness complex, which is the result of historical claims between two countries and also identifying Polishness with prestige. The subject of presented analysis; relations between Poland and Lithuania; was examined on the strength of mimetic theory of French anthropologist René Girard (1923-). Keywords: chauvinism, divide and rule, Lithuania, mimetic rivalry, nationalism, Poland, scapegoat.
