The article is dedicated to the Muslims in Poland, with a special focus on their institutional representation. This religious minority encircles a diverse populace in terms of the path in Islam they adhere to, ethnicity, country of origin, but also the legal status they have in Poland. It includes Muslim Tatars, former students from Arab countries who have been living in this country for decades, as well as transient groups war refugees from Chechnya, Afghanistan or the Balkans, esp. Bosnia and Herzegovina. The author argues that institutionalized entities of religious character which associate Muslims in the country, organize their presence in religious terms and represent them, reflect major divisions within the Muslim populace in the country. A key factor is the duration of their settlement – it is concomitant to, if not more important than, tensions between the Sunnis and Shiites.
