The Lipka Tatars (Lipka – refers to Lithuania, also known as Lithuanian Tatars; later also – Polish Tatars, Polish-Lithuanian Tatars, Lipkowie, Lipcani, Muślimi, Lietuvos totoriai) are a Turkic ethnic group who originally settled in the Grand Duchy of Lithuania at the beginning of the 14th century. The first Tatar settlers tried to preserve their shamanistic religion and sought asylum amongst the non-Christian Lithuanians. Towards the end of the 14th century, another wave of Tatars – this time, Muslims, were invited into the Grand Duchy by Vytautas the Great. These Tatars first settled in Lithuania proper around Vilnius, Trakai, Hrodna and Kaunas and later spread to other parts of the Grand Duchy that later became part of Polish–Lithuanian Commonwealth. These areas comprise parts of present-day Lithuania, Belarus and Poland. From the very beginning of their settlement in Lithuania they were known as the Lipka Tatars. While maintaining their religion, they united their fate with that of the mainly Christian Polish–Lithuanian Commonwealth. From the Battle of Grunwald onwards the Lipka Tatar light cavalry regiments participated in every significant military campaign of Lithuania and Poland. The Lipka Tatar origins can be traced back to the descendant states of the Golden Horde, the Crimean Khanate and Kazan Khanate. They initially served as a noble military caste but later they became urban-dwellers known for their crafts, horses and gardening skills. Throughout centuries they resisted assimilation and kept their traditional lifestyle. While they remained very attached to their religion, over time they lost their original Tatar language, from the Kipchak group of the Turkic languages and for the most part adopted Belarusian, Lithuanian and Polish. There are still small groups of Lipka Tatars living in today's Belarus, Lithuania and Poland, as well as their communities in the United States. Name The name Lipka is derived from the old Crimean Tatar name of Lithuania. The record of the name Lipka in Oriental sources permits us to infer an original Libķa/Lipķa, from which the Polish derivative Lipka was formed, with possible contamination from contact with the Polish lipka "small lime-tree"; this etymology was suggested by the Tatar author S. Tuhan-Baranowski. A less frequent Polish form, Łubka, is corroborated in Łubka/Łupka, the Crimean Tatar name of the Lipkas up to the end of the 19th century. The Crimean Tatar term Lipka Tatarłar meaning Lithuanian Tatars, later started to be used by the Polish–Lithuanian Tatars to describe themselves. In religion
