Bedouins [1]

Arabs who lead a nomadic life in the desert and subsist by the pasture of cattle and the rearing of horses, the one element that binds them into a unity being community of language, the Arabic namely, which they all speak with great purity and without variation of dialect; they are generally of small stature, of wiry constitution, and dark complexion, and are divided into tribes, each under an independent chief.
