Today those who are recognized by the government are entitled to royal titles and styles (manner of address), and perform official engagements and ceremonial duties of state.
The extended family of the King (Swedish: Sveriges kungliga familj) consists of other close relatives who are not royal and thus do not represent the country officially.
An exceptional case is that of Saint Bridget (1303–1373) who outside of Sweden became known as the Princess of Nericia,[1] a title which appears to have been a noble, rather than a royal one, since she was not the daughter of a king.
Until the 1620s Swedish provinces were granted as territorial appanages to royal princes which, as dukes thereof, they governed semi-autonomously.
Beginning during the reign of Gustav III, and as codified in § 34 of the 1772 Instrument of Government, provincial dukedoms have existed in the royal family as nominal non-hereditary titles only, without any inherent property ownership or trust attached to them; although several members of the royal family have maintained a special public connection to, and sometimes a secondary residence in, "his or her duchy".
