The nomadic Amazigh people trace their African roots back to 2000 B.C.E. (Nomads are peoples who have no fixed place of residence and wander from place to place usually with the seasons or as food sources become scarce.) Over the years since then, their dress has changed with the influences of invading cultures. Influenced by the past colonization of ancient Romans, whose power was felt in the region from about 509 B.C.E. to 476 C.E., many Amazigh continue to wear a haik, a large cloth wrapped around the body in a fashion similar to a Roman toga. When Arabs conquered their territory in the twelfth century C.E., the Amazighs were influenced by the Muslim religion.
