The Royal Family Order of Saints George and Constantine (Greek: Βασιλικό Οικογενειακό Τάγμα των Αγίων Γεωργίου και Κωνσταντίνου ) is an order of the Greek royal family.
 For the duration of its existence, it has been the second highest decoration awarded by the modern Greek state and the Greek crown, after the Order of the Redeemer.
 It was instituted in January 1936 by King George II in the memory of his grandfather (King George I) and his father (King Constantine I).
 The order is awarded only to men, while the corresponding Order of Saints Olga and Sophia is reserved for women.
 The order's design was influenced by the royal family's Danish origin, evoking the appearance of the Order of the Dannebrog.
 The order is not awarded since 1975 by the Greek state after the abolition of monarchy and today is awarded only by the Greek Royal Family.
In Canada, a number of sites and structures are named for royal individuals, whether a member of the past French Royal Family, British Royal Family, or present Canadian Royal Family thus reflecting the country's status as a constitutional monarchy under the Canadian Crown.

"Doomwar" is a 2010 event storyline published by Marvel Comics.

A royal family order is a decoration conferred by the sovereign of a royal family in a monarchy to female members of the royal family, since female members of the royal family traditionally do not wear the commemorative medals that men wear.
 Such an order is considered more of a personal memento than a state decoration, although it may be worn during official state occasions.
 The only way to know whom the order has been bestowed is to see the recipient wearing it.
The Royal Family Order of King Harald V of Norway is a Royal Family Order bestowed by the King of Norway upon female members of the Norwegian Royal Family.
 Unlike the other two Royal family orders, it is currently awarded.
Canadian royal tours in the 21st century carry on the tradition of the previous 300 years, either as an official tour, a working tour, a vacation, or a period of military service by a member of the Royal Family.
 Originally, official tours were events predominantly for Canadians to see and possibly meet members of their royal family, with the associated patriotic pomp and spectacle.
 However, nearing the end of the 20th century, such occasions took on the added dimension of a theme; for instance, the 2005 tour of Saskatchewan and Alberta by Queen Elizabeth II and Prince Philip, Duke of Edinburgh, was deemed to be a vehicle for Her Majesty and all other Canadians to honour "The Spirit of Nation Builders".
 Also, junior members of the Royal Family began to undertake unofficial "working" tours of Canada as well; in this method, royal figures are invited by provinces, municipalities, and other organizations to events which the latter fund without assistance from the federal government.
 Charles, Prince of Wales; Anne, Princess Royal; Prince Andrew, Duke of York; and Prince Edward, Earl of Wessex, and Sophie, Countess of Wessex, have all made several small tours in this fashion.
The Royal Family Order of King George IV was an honour bestowed as a mark of personal esteem on female members of the British Royal Family by King George IV.
 It was the first Royal Family Order issued in the United Kingdom.
 Prior to George IV's accession in 1820, both ladies and gentlemen of the Court, as well as female members of the royal family, had worn the Sovereign's portrait set in a jewelled frame.
 George IV formalised the order.
