vaults. Unlike in Jerba, the distinctive minarets in this region are tall and have a square base, tapering towards the end and crowned with "horn"-like corners. Culture and arts Social context The traditional social structure of the Berbers has been tribal. A leader is appointed to command the tribe. In the Middle Ages, many women had the power to govern, such as Dihya and Tazoughert Fatma in the Aurès Mountains, Tin Hinan in the Hoggar, Chemci in , in the Aurès. Lalla Fatma N'Soumer was a Berber woman in Kabylie who fought against the French. The majority of Berber tribes currently have men as heads of the tribe. In Algeria, the el Kseur platform in Kabylie gives tribes the right to fine criminal offenders. In areas of Chaoui, tribal leaders enact sanctions against criminals. The Tuareg have a king who decides the fate of the tribe and is known as Amenokal; it is a very hierarchical society. The Mozabites are governed by the spiritual leaders of Ibadism and lead communal lives. During the crisis of Berriane between the Maliki and Ibadite movements, the heads of each tribe began talks to end the crisis and resolved the problem. In marriages, the man usually selects the woman, and depending on the tribe, the family often makes the decision. In contrast, in the Tuareg culture, the woman chooses her future husband. The rites of marriage are different for each tribe. Families are either patriarchal or matriarchal, according to the tribe. Traditionally, men take care of livestock. They migrate by following the natural cycle of grazing, and seeking water and shelter. They are thus assured of an abundance of wool, cotton, and plants used for dyeing. For their part, women look after the family and handicrafts – first for their personal use, and secondly for sale in the souqs in their locality. Visual arts The Berber tribes traditionally weave kilims (tapestry-woven carpets), whose designs maintain the traditional appearance and distinctiveness of the region of origin of each tribe, which has in effect its own repertoire of drawings. The plain weave textile designs include a wide variety of stripes and, more rarely, geometrical patterns such as triangles and diamonds. Additional decorations such as sequins or fringes, are typical of Berber weave in Morocco. The nomadic and semi-nomadic lifestyle of the Berbers is suitable for weaving kilims. In Algeria, the cloak-like kachabia is typical Berber masculine
