The dynastic succession regime was codified in the first Constitution of the independent Morocco and rehearsed in the following Constitutions with some modifications brought by the constitutional revision of May 23, 1980. Article 20 of the present Constitution holds that “The Moroccan Crown and the constitutional rights thereof shall be hereditary and handed down, from father to son, to descendants in direct male line and by order of primogeniture among the offspring of His MAJESTY KING HASSAN II, unless the King should, during his lifetime, designate a successor among his sons apart from the eldest one. In case of failing descendants in direct male line, the right of succession to the Throne shall, under the same conditions, be invested in the closest male in the collateral consanguinity”.
