Lipka Tatars
Small populations of Polish Lipka Tatars still exist and still practice Islam. Some Polish towns, mainly in northeastern Poland (in Podlaskie Voivodeship) have mosques. Tatars arrived as mercenary soldiers beginning in the late 14th century. The Tatar population reached approximately 100,000 in 1630 but the 2002 census showed only 447 people declaring this ethnicity.
