Who was the Last King of Saxony?
Line of succession to the former Saxon thrones
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 Rüdiger of Saxony, the only agnatic great grandson of the last King of Saxony, claiming the headship.
Princess Frederica Caroline of Saxe-Coburg-Saalfeld
Princess Frederica Caroline of Saxe-Coburg-Saalfeld, Duchess in Saxony (24 June 1735 – 18 February 1791) was a princess of Saxe-Coburg-Saalfeld by birth and through marriage the last Margravine of Brandenburg-Ansbach and Bayreuth.
