Illustrious Highness
The family was mediatized in 1806 and 1815, however without the loss of its equal-to-royal rank, and the two states were incorporated into Bavaria. In 1901, both branches received the Bavarian rank of Prince (only in primogeniture), with the title of Prince (Serene Highness) for the heads of the branches and the title of Count/Countess (Illustrious Highness) for all other members of the House.
