Abstract EN:

From the second to the seventh century h, eighth to the thirtenth century J. C. , berber dynasties came into power in the maghrig. The dynasty historiography convied a message which tried to legitimate the power. While in the tenth century, the banu ziri endowed themselves with a yemeni descent, during the twelfth to the thirteenth century, the muwahhidun followed by the banu zayyan declared themselves as descendants from the prophet. The development within the genealogies led, on one part, to underline that the banu ziri, while refering to a yemeni descent, fitted into the struggles which opposed the various parties of the arab power, while on the other part, the following dynasties tended to the setting up of a caliphate power. The dynasty genealogies went with a speech which tried to justify the succession rules. Even though, berber tradition prefered the succession by the ancients, the dynasts commanded the succession by primogeniture. This way of handing over, which has been contested by the dynast family, was legitimated through the claim to the miracles which transcended tradition and made the founder enjoy of the ancestor virtues.
