The Roman Court or Papal Curia was reformed by the papal bull Pontificalis Domus issues by Pope Paul VI in 1969. It abolished the role of the old Roman nobility at the papal court with the exception of the position of Prince Assistant to the Papal Throne. The titles abolished, such as the Grand Master of the Sacred Apostolic Hospice and Marshal of the Holy Roman Church and the Sacred Conclave, remain heredity but are now purely honorary.

This position of Prince Assistant had been shared jointly by the Princes Orsini and Colonna,^[1] but the former was deprived of the title by Pope Pius XII after he obtained a divorce and the title was conferred upon Prince Torlonia, Prince of Fucino, Canino and Musignano of the Torlonia family.

The Prince Assistants are representatives of the Roman nobility, who serve at the feet of the Throne immediately next to the cardinal deacon who stands to the right of the pope. They alternate in fulfilling the functions of the office and no one can substitute for them. Their principal function is to serve on the occasion of official visits by a head of state.

The reforms of 1969 also abolished the various categories of Secret Chamberlains of the Cape and Sword and changed this title to Gentlemen of His Holiness. Other offices were abolished altogether, but officeholders were reassigned.
