Kalmyks

 (Kalmyk: Хальмгуд, Xaľmgud; Mongolian: Халимагууд, romanized: Halimaguud; Russian: Калмыки, romanized: Kalmyki; archaically anglicised as Calmucks) are the only Mongolic-speaking people living in Europe, residing in the easternmost part of the European Plain. They are the only traditionally Buddhist people who are located within Europe. Through emigration, small Kalmyk communities have been established in, France, Germany, and the Czech Republic.
