"The Khas, Magars, Gurungs, and Thakurs are the military tribes of the kingdom, from which the fighting element of the Nepalese army is drawn. They are the descendants of the aboriginal tribes who intermarried with Rajputs and other Hindus who took refuge from Muhammadan conquest in the hills of Nepal in the twelfth century.Since the Gurkha conquest, they have spread throughout the whole country, though their real habitat is to the west of the Valley of Nepal. It is to these tribes that the often misapplied term ‘ Gurkha or ‘ Gurkhali ' should be confined."
