->''"So, we lie. How did the nobles become [[BlueBlood noble]] in the first place? They took it! At a tip of the sword! I'll do it with a lance... A man can change his stars. I won't spend the rest of my life as nothing."''
-->-- '''William''', ''AKnightsTale''

A character wishes to become a knight but cannot, either because of gender, social class, or some other limitation. Thus they either lie about being a knight, or set out to become one in secret, often using a helmet to conceal their true identity. The character's motivation for becoming a knight can vary: sometimes they seek to prove themselves, sometimes they wish to escape another fate, or perhaps they aspire to the ideal and romance of becoming a KnightInShiningArmor or KnightErrant. Often will be known by a descriptive title like "BlackKnight" or similar, or may be using a suitably noble sounding alias. Generally the deceit can last a good while, whether in war or TheTourney.

The knight's identity may either be revealed, normally alongside AnAesop about prejudice, or remain a mystery and become some sort of legend that inspires the people. May also involve the character actually being knighted for real at the end for their heroism.

For this character to be the hero is a modern trope. In eras with actual knights, this character is very rare and a joke when he does appear, often a MilesGloriosus, because [[ValuesDissonance nobility was a God-given right and the lower classes were supposed to accept their lot in life]].

[[folder:Anime And Manga]]
* ''{{Yaiba}}'' has Frederick Luther III, who claims to be a knight. His behaviour in battle proves otherwise.
* Happens in ''Anime/SamuraiSeven'', which is a remake of ''Film/SevenSamurai'' (see below).
* Leopold Scorpos from ''LightNovel/ScrappedPrincess'' rides around the land like a KnightErrant, despite not technically having been knighted (which he also strives to be).

[[folder:Film]]
* ''AKidInKingArthursCourt'' reveals its master jouster Black Knight to be [[spoiler:[[SamusIsAGirl the princess]]!]]
* Two of these end up coming into ''AKnightsTale''. One is the classic struggling underdog, William Thatcher, the peasant who's masquerading as the knight Ulrich Von Lichtenstein, and the other is the royal in disguise, Sir Thomas Colville or Edward, the Black Prince, who just wants a chance to actually ''compete'' and earn something himself instead of being given everything because of his station.
* In the 1954 film, ''The Black Knight'', John, a blacksmith and swordsmith, is tutored at [[KingArthur Camelot]]. As a commoner, he can't hope to win the hand of Lady Linet, daughter of the Earl of Yeoniland, so he creates a secret alternate identity as the Black Knight.
* ''Film/ReturnOfTheJedi:'' Luke Skywalker declares himself ([[InsistentTerminology repeatedly]]) to be a Jedi Knight. [[DudeWheresMyRespect Not a single character takes his claim seriously]], due to the Jedi Order's [[ThePurge near-total destruction]] decades before, [[spoiler: until Emperor Palpatine's PreMortemOneLiner.]]
* In the ''Film/RobinHood2010'' movie, Robin takes over the identity of dead knight Robert Loxley.
* In ''Film/SevenSamurai'', Kikuchiyo (played by Toshiro Mifune) is the samurai equivalent. In caste-based feudal Japan, one has to be born into the samurai class, and his manners and [[TheReasonYouSuckSpeech mid-film epic rant]] make it clear that he was born a peasant. At one point he produces a family history scroll to prove to the other samurai that he is from a noble family, but it is obviously fake, bought, and/or stolen: according to its timeline, he would be thirteen years old, and 'Kikuchiyo' is a girl's name. It would be like a male European peasant proclaiming himself "Sir Susan".
* In ''Film/WilliamShakespearesRomeoAndJuliet'' Romeo dresses up as a knight who travels as a pilgrim to the shrine of Juliet.

[[folder:Literature]]
* Alanna in the first half of ''Literature/SongOfTheLioness'' pretends to be a boy named Alan so that she can train for knighthood. After she earns her shield the lie becomes known and she leaves in search of adventure. Her knighthood is recognized, though, since one's worth to be a knight is ''really'' decided by a minor EldritchAbomination that approves of her.
* In ''ASongOfIceAndFire''
** Brienne of Tarth isn't allowed to be a knight because she's a woman, but she fights and acts like knights are supposed to act better than most of the real ones. This has gained her, on the whole, very little respect.
** It's implied that Dunk, the hero of the "Literature/TalesOfDunkAndEgg" short stories, was never actually knighted by his master. He claims that his master knighted him before he died, but he is repeatedly afflicted by unexplained guilt when the issue gets raised. Ironically, he might be an ancestor to Brienne, given that his arms appear in her father's keep.
** Mystery Knights are tournament competitors who refuse to give their real names, making it ambiguous as to whether they're true knights or not. There are a few examples of people who aren't knights entering the lists as mystery knights, including Barristan Selmy when he was still a squire. There's some evidence that "The Knight of the Laughing Tree" at the Tourney at Harrenhal was actually [[SweetPollyOliver a disguised Lyanna Stark]].
** Ser Osmund Kettleblack, claims he was knighted by "Ser Robert... Stone," which is about as generic and untraceable a name as MrSmith.
* ''Literature/DonQuixote de la Mancha'' who reads novels about Chivalry and sets out to revive chivalry as a self-proclaimed knight. This example is PlayedForLaughs (before the onset of CerebusSyndrome) as in the time ''Don Quixote'' takes place, wandering knights no longer exist.
** Bear in mind, however, that Don Quixote's status as a member of the landed gentry is not in question (he's an ''hidalgo''); it's the whole "knight-in-shining-armor" thing that qualifies him.
** To elaborate: Don Quixote is truly GenreSavvy at ChivalricRomance books. Chapter III shows him aware of this trope and he tries to defy it when he insists to [[ThePresentsWereNeverFromSanta an innkeeper (who he thinks is a castellan)]] [[{{Knighting}} to knight him after he has watched his armor in the castle chapel -- that is, in the stable of the inn]]. So DonQuixote believes he has averted this trope. However, ''Las partidas de Alfonso el Sabio'', the spanish chivalry code, states that a man cannot be knighted if he is too poor or if he is knighted as a joke… so, Don Quixote, being an ImpoverishedPatrician [[{{Irony}} trying to defy this trope, only has enforced it]].
* In EdmundSpenser's ''Literature/TheFaerieQueene'', Braggadocio. A MilesGloriosus whose name is the origin of the noun.
[[/folder]]

[[folder:Live Action TV]]
* ''Series/SamuraiSentaiShinkenger'' and ''Series/PowerRangersSamurai'' use samurai instead of knights, but the situation's the same. Where the Rangers came from long lineages of samurai, the SixthRanger is an old friend of the Red Ranger's; teaching himself to fight and building his own gear to fill a promise to help his buddy. The Rangers are reluctant to involve him in the fighting at first, but they soon accept his help.
* Lancelot in ''{{Series/Merlin}}''. He isn't a noble, so he can't become a knight, but lies about it to enter the tournament. Uther finds out and only spares his life because he believes Lancelot killed the griffin. Later, Arthur knights him for real. Gwaine zig zags the trope: He is a noble but does not reveal that, so he can't be a knight and eventually gets exiled after trying to stop a couple of guys impersonating knights with magic (further examples of the trope). Later, he gets knighted like Lancelot did.
** Arthur also hires a commoner to act as a knight and enter the jousting tournament. While the commoner, William, would show his face in between jousts it would be Arthur, with his face covered, who actually did the jousting. Arthur does this to show he can win a jousting tournament without any favoritism due to his station.
* The ''{{House}}'' episode ''Knight Fall'' starts in a medieval reenactment community. A knight collapses in battle. While in the hospital William tells how he tries to live by the knight's code of honor.

[[folder:Video Games]]
* Mazoga the Orc from ''VideoGame/TheElderScrollsIVOblivion'' says she's a knight, she just sort of decided she'll call herself that one day when her best friend was murdered - deciding she was a knight and taking an oath to avenge him. If she survives the two quests on which she accompanies you, she'll have a chance to become a real knight (as will you) when the local count is impressed by her and your honorable attitude.
* Sterkenburg Cranach in the ''Arland'' trilogy of the ''Franchise/{{Atelier}}'' series. He ''was'' an actual knight in ''VideoGame/AtelierRorona'', but between that game and ''Videogame/AtelierTotori'', Arland has changed from monarchy into a Republic, and disbanded the knights. He travelled the lands trying to find the disappeared former king, while keep calling himself a knight. He continues this in ''VideoGame/AtelierMeruru''.
