Loi salique
The Salic law, or agnatic succession, restricted the pool of potential heirs to males of the patrilineage, and altogether excluded females of the dynasty and their descendants from the succession. The Salic law applied to the former royal or imperial houses of Albania, France, Italy, Romania, Yugoslavia, and Prussia/German Empire. It currently applies to the house of Liechtenstein, and the Chrysanthemum Throne of Japan.
