Illustrious Highness
After the Reichsdeputationshauptschluss in 1803, with many others of the nobility, the members of the house were named as "Standesherren", and the family with once sovereign "territorial" lordship had to forfeit its judicial and legal rights, but retained its social and cultural standing as a sovereign "family" mediatized to Saxony. In 1818, the House petitioned the German Confederation to recognize the family; in 1828 the Parliament vouchsafed the personal and family rights that had been abrogated in 1806. The House was granted two seats in the Upper House of the Kingdom of Saxony in 1831. In 1878 they lost their last rights of partial sovereignty, however the King of Saxony decreed that all members of the family were to be known as Illustrious Highness, while members of the princely lines were a Serene Highness.
