Salic law
A number of military conflicts in European history have stemmed from the application of, or disregard for, Salic law. The Carlist Wars occurred in Spain over the question of whether the heir to the throne should be a female or a male relative. The War of the Austrian Succession was triggered by the Pragmatic Sanction of 1713 in which Charles VI of Austria, who himself had inherited the Austrian patrimony over his nieces as a result of Salic law, attempted to ensure the inheritance directly to his own daughter Maria Theresa of Austria, that being an example of an operation of the "Semi-Salic law".
