TangutansTangutans (i.e. "Dwellers in houses"), a term formerly applied by the Mongolian nomads (dwellets in tents) to the Tibetans in general, but now restricted to the north-eastern branch or that race in the West Kansu uplands, the Roko-Nor, Tsaidam, and Upper Hoang-ho basins. This region is supposed to be the original home of the Tibetans, who migrated southwards to Lhassa about 400 B.C. In mediaeval times the Tangutans, who always call themselves Bod-pa, like all other Tibetans, rose to great power and established a strong kingdom, which about coincided with the limits of the Chinese province of Kansu taken in its widest sense. They are described by Prjevalsky as of somewhat gipsy-like appearance, above the mean height, with thickset figures, broad shoulders, large dark eyes, straight and even aquiline nose, long face, thick beard and whiskers, and tawny complexion.
