Loi salique
In this form of succession, the succession is reserved first to all the male dynastic descendants of all the eligible branches by order of primogeniture, then upon total extinction of these male descendants to a female member of the dynasty. The only current monarchy that operated under semi-Salic law until recently is Luxembourg, which changed to absolute primogeniture in 2011. Former monarchies that operated under semi-Salic law included Austria (later Austria-Hungary), Bavaria, Hanover, Württemberg, Russia, Saxony, Tuscany, and the Kingdom of the Two Sicilies.
