History Main / RoyalBlood

!!!'''By Author:'''
* Commonplace in Creator/EdgarRiceBurroughs's works, especially the ''Literature/JohnCarterOfMars'' ones. [[RagsToRoyalty Though some don't know it]].
** In ''The Chessman of Mars'', Corpals "[[{{Necromancer}} that by commanding the spirits of the wicked dead gains evil mastery over the living]]" are said to be killable only by those of Royal Blood. And the weak and cowardly king cannot be deposed for a noble and brave nobleman; fortunately, he also has a brave and popular son whom he hasn't killed yet.
** In ''Literature/TheMadKing'', the hero is an American visiting the {{Ruritania}}n kingdom of Lutha, where his mother was born. Partway through the novel, he learns that his mother was a runaway member of the Luthanian royal family, and he himself is in line for the throne. This is a mixed blessing; it means he's got some chance with the Luthanian noblewoman he's fallen in love with, but it also stokes the king's paranoia about the hero being part of a plot to usurp him. [[spoiler:In the end, the king gets himself killed, and the hero marries the noblewoman and succeeds to the throne]].
* Invoked in Creator/GKChesterton's ''Magic'':
-->'''DUKE'''. Why, the Professor here who performs before the King [''puts down the programmes'']--you see it on the caravans, you know--performs before the King almost every night, I suppose...\\
'''CONJURER'''. [''Smiling.''] I sometimes let his Majesty have an evening off. And turn my attention, of course, to the [[BlueBlood very highest nobility]].
** ''Literature/TheNapoleonOfNottingHill'': This has been abandoned.
--->''To avoid the possible chance of hereditary diseases or such things, we have abandoned hereditary monarchy. The King of England is chosen like a juryman upon an official rotation list.''
* In Creator/UrsulaKLeGuin's works:
** In ''Literature/AlwaysComingHome'', it is stated that when the Condor's son was to be executed, no one dared to raise a hand against a man of Royal (near-divine, according to their ideology) Blood. Instead they gave him the chair, and said it was electricity that killed him.
** ''Literature/{{Earthsea}}'': In ''Literature/AWizardOfEarthsea'', Ged found an old man and woman stranded on an island. In the sequel ''Literature/TheTombsOfAtuan'', Tenar explains that they were a prince and princess, the last of their family, whom the God Emperor had abandoned at sea as infants as he feared to kill those of Royal Blood.
!!!'''By Work:'''

* There was a Literature/ChooseYourOwnAdventure book, ''Black Vein Prophecy'' where you are a member of a family of Royal Wizards.

* In Creator/RobertEHoward's Literature/ConanTheBarbarian story "Literature/ThePeopleOfTheBlackCircle", Yasmina is very proud of hers. It makes the BreakTheHaughty all the more humiliating.
-->''"But for all your stupidity, you are a woman fair to look upon. It is my whim to [[MadeASlave keep you]] for [[SexSlave my slave]]."\\
The daughter of a thousand proud emperors gasped with shame and fury at the word.\\
"You dare not!"\\
His mocking laughter cut her like a whip across her naked shoulders.''

* In Mary Stewart's ''Literature/TheCrystalCave,''since it's a retelling of the Arthurian story, only Arthur can claim the sword and hence the throne. [[/folder]]

* ''Anime/{{Daltanious}}'': Kloppen has a complex about being superior because he's the son of the last Emperor of Helios, before the empire fell. [[spoiler: To his horror, Kloppen finds out that he's a clone, and the real Prince of Helios is his ArchEnemy Harlin.]]

* ''Anime/MyOtome'': The members of the Windbloom royal family have the inherited ability to activate LostTechnology. This becomes important later, as some believe Mashiro to be an impostor, and therefore unable to activate the Harmonium. [[spoiler:While Mashiro was able to activate it a little, since she knew the song and had an Otome with her, she couldn't unlock its full power because she was indeed an impostor. ''Nina'', however, is the real Mashiro, and since she fills all three requirements (is a Windbloom, knows the song, and is an Otome), she unlocks its full power.]]
* ''Anime/CastleInTheSky'': The ancient floating city of Laputa was ruled by a royal family in its heyday, and only full-blooded members of that family could use its technology/magic fully. By the present day, the Laputan royal family has died out, with no known survivors. [[spoiler:Both Sheeta and the [[BigBad main villain]], Muska, are later revealed to be descendants of the Laputan royalty, making them (very distant relatives). Muska needs Sheeta (or more specifically, the necklace she wears that is a royal heirloom) in order to access the ruins of Laputa; once he succeeds, he intends to restore Laputa to its former glory and take over Earth as its ruler.]]

* In ''WesternAnimation/ThePrincessAndTheFrog'', Naveen has it on both sides of his family, according to Facilier -- who claims that he himself is royal on his mother's, though it's hard to tell whether he's serious.
