The Kingdom of Saxony was abolished in 1918 when King Frederick Augustus III of Saxony abdicated. The succession law until the abolition of the monarchy was semi-Salic primogeniture and required the successor to be born of an equal marriage, approved in advance by the head of the house. Accordingly, the last undisputed male member of the family was Prince Albert of Saxony, who assumed the headship of the royal house and the title Margrave of Meissen upon the death of his brother the Margrave Maria Emanuel in July 2012. This was challenged, however, by his nephew Prince Alexander of Saxe-Gessaphe who also claimed the headship based on a 1997 agreement, and who is said to have reached an agreement with Albert just prior to the funeral of Maria Emanuel which recognised Alexander as the dynasty's heir. With the death of Albert in October 2012 the dispute continued with Prince Ruediger of Saxony, the only agnatic great grandson of the last King of Saxony, claiming the headship.
The conflict over the headship stems from the fact that the last undisputed head of the house Maria Emanuel, Margrave of Meissen, and the other princes of his generation either had no children or, in the case of Prince Timo, had children (including Prince Ruediger of Saxony) who were not recognised by Margrave Maria Emanuel as dynastic members of the Royal House of Saxony. The first designated dynastic heir of Maria Emanuel was his and Albert's nephew Prince Johannes of Saxe-Coburg and Gotha, only son of their youngest sister Princess Mathilde of Saxony by her marriage to Prince Johannes Heinrich of Saxe-Coburg and Gotha, dynast of a ducal branch of the House of Wettin senior patrilineally to the royal branch.
