Thurn and Taxis line of succession The House of Thurn and Taxis, a princely dynasty which was sovereign until mediatized in 1806 and its noble status de-recognized following the fall of the German Empire in 1918, exists through several extant lines descending from Alexander Ferdinand, 3rd Prince of Thurn and Taxis. The rule of succession is agnatic primogeniture, which only allowed males to succeed to the main princely title so long as male members of the family survive. The current Head of the House of Thurn and Taxis is Albert, 12th Prince of Thurn and Taxis, whose historic style is "His Serene Highness" Albert, Prince of Thurn and Taxis.
