The aim of this article is to describe regionalism in the Warmia and Mazuria region. Although the majority of indigenous inhabitants emigrated from the region after 1945, some intellectuals who did not leave Poland established several organizations that focused on activities which may be described as ‘old regionalism’. Taking into account the political context, they tried to save the regional culture. After 1989 (the beginning of the transition period in Poland) new organizations were founded. Their members try to create a new type of regional culture and identity – a synthesis of cultures and identities of all cultural and ethnic groups living in Warmia and Mazuria. These new kinds of activities should be called ‘new regionalism’.
