a people spread over nearly the whole of northern Africa west of Egypt, from whom the name Barbary is derived. The chief branches into which the Berbers are divided are, first, the Amazirgh, or Amazigh, of northern Morocco, numbering from 2,000,000 to 2,- 500,00C. They are for the most part quite independent of the Sultan of Morocco, and live partly under chieftains and hereditary princes and partly in small republican communities. Second, the Shulluh, Shillooh, or Shellakah who number about 1,450,000, and inhabit southern Morocco. They are more highly civilized than the Amazirgh. Third, the Kabyles in Algeria and Tunis, who are said to number 1,000,000; and fourth, the Berbers of the he Sahara, who inhabit the oases. Among the Sahara Berbers the most remarkable are the Beni-Mzak and the Tuaregs. To these might be added the Guanches of the Canary Islands, now extinct, but undoubtedly of the same race. The Berbers generally are about the middle height; their complexion is brown, and sometimes almost black, with brown and glossy hair. They are sparely built, but robust and graceful; the features approach the European type. Their language has affinities to the Semitic group, but Arabic is spoken along the coast. They are believed to represent the ancient Mauritanians, Numidians, Gætulians, etc. The Berbers live in huts or houses, and practice various industries. Thus they smelt iron, copper, and lead; manufacture gun barrels, implements of husbandry, etc., knives, swords, gunpowder, and a species of black soap. Some of the tribes breed mules, asses, and stock in considerable numbers, others practice agriculture.
Aiton's Encyclopedia (1910)
ber'bers, a people spread over northern Africa, particularly along the southern shore of the Mediterranean. They have a brown complexion, with dark, glossy hair, and are active and robust. Their language and features are akin to the Egyptians, rather than to the Arabs, by whom they have been, in a way, subjugated. They number five or six million and are found chiefly in Algiers, Morocco, and the Sahara, their chief stronghold being the northern Sahara and the Atlas Mountains. The Berbers vary greatly. Many tribes preserve an independence akin to that of Bedouin Arabs. Others have settled down to agriculture, and have become an industrious, skillful race, quite able to manufacture their own guns, powder, and soap. They perform a large part of the agricultural work in Algiers, and are famous raisers of cattle and goats. The mountain tribes that give the Sultan of Morocco so much trouble by carrying off prisoners to be held for ransom are of this race. See Algiers ; Vandal 2026 Editor's Note: The Berbers call themselves Amazigh — "free people" — and after a century of pressure to Arabize, their language has been officially recognized at last: Tamazight became an official language of Morocco in 2011 and of Algeria in 2016, and is now taught in schools and written in the ancient Tifinagh script.
