Document 2: Greek royal family: The Greek royal family (Greek: Ελληνική Βασιλική Οικογένεια) is a branch of the House of Glücksburg that reigned in Greece from 1863 to 1924 and again from 1935 to 1973. Its first monarch was George I, the second son of King Christian IX of Denmark. He and his successors styled themselves "Kings of the Hellenes". Most members of the dynasty (aside from the last king to reign, Constantine II and his queen consort, Anne-Marie of Denmark) hold the title "Prince or Princess of Greece and Denmark" with the style "Royal Highness", except Marina, Consort of Prince Michael, and their daughters Princess Alexandra and Princess Olga.

Document 6: Dynastic order: A dynastic order, monarchical order, or house order, is an order under royal patronage, bestowed by the head of a currently or formerly sovereign royal family as legitimate fons honorum. These are often considered part of the cultural patrimony of the royal family. They are orders of chivalry, and orders of merit just as those distributed by sovereign states, but dynastic orders were often founded or maintained to reward service to a monarch, or the monarch's subsequent dynasty. An example of this difference is seen between the Royal Victorian Order, in which appointments are made as a personal gift of the sovereign, thus is a dynastic order, and the Order of the British Empire, in which appointments are made by the sovereign on the basis of recommendations by the Prime Minister, and thus a national order.

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.

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.
Document 14: Order of Menelik II: The Order of Menelik II is an Ethiopian order established in 1924 by then-Regent Tafari Makonnen, during the reign of Empress Zewditu I, to honor the memory of Emperor Menelik II.

Document 15: Order of Prince Danilo I: The Order of Prince Danilo I of Montenegro (Montenegrin: Орден Књаза Данила I, Orden Knjaza Danila I) was an order of the Principality, and later Kingdom, of Montenegro. It is currently granted as a dynastic honor by the undisputed head of the House of Petrović-Njegoš, Nicholas Petrović Njegoš II. Although no longer a state order, recognition is indicated by the acceptance of the former President of Montenegro, Filip Vujanović. More formal recognition by the Republic of Montenegro is implicit in the 2011 "Law on the Status of the Descendants of the Petrović Njegoš Dynasty", which recognizes the current crown prince as head of the Royal Family and specifically sanctions the use of the royal family's heraldic symbols. The act also provides the Crown Prince housing and a pension and has been noted as conferring a sort of "quasi restoration" of the throne. In a May 15th "Pobjeda" newspaper interview, Prince Nikola cited Article 3 of this law as the basis for his May 5th re-institution of the Order, which he emphasized was "historically an extremely valuable Montenegrin decoration." He went on to explain that the order can be awarded to Montenegrin nationals and worthy foreigners on two general grounds: (1), for support and affirmation of Montenegrin independence and the royal tradition of the Petrovic Njegos dynasty, and (2) to those whose "scientific or social work contributed to the development of culture, art and science." The Order has since been bestowed on a number of high dignitaries internationally. In an April 17, 2016 visit to Rome, HRH Prince Nikola II Petrovic Njegoš met with Pope Francis and other high Vatican officials bestowing the dynastic honor on the Cambodian ambassador, His Highness Prince Sisowath Ravivaddhana Monipong, the Montenegrin ambassador to the Holy See Veselin Šuković, as well as the U.S. Ambassador to the Holy See Kenneth Francis Hackett, and the ambassador of Hungary HIRH Eduard von Habsburg-Lothringen, among several other Vatican officials and Italian nobles. The official Representative of the Royal House and the order is H.E. Giuseppe Tedischi GCDO, who also has the Vatican charge "Addetto di Anticamera di Sua Santità," or Officer of Antechamber of His Holiness.
