ENThe aim of this article is to describe language situation of Polish minority in Lithuania with a special focus on education system. Our research is based on Rogers Brubaker’s theoretical conception, which mentions three sources of nationalism: national state, national minority and external national homeland, as well as the theory of public discourse, which states that the media (as the basis for interpretation and creation) influence social reality. We analyse public sources i.e. documents of the Polish Ministry of Foreign Affairs, newspaper articles looking for examples of nationalism coming from three sources: Polish minority in Lithuania, Lithuanian and Polish state.
