->''"Respect has nothing to do with how long you've been on this Earth... but you're probably too young to understand that."''
-->-- '''Nudge the Pirate''' referring to '''Tetra''', ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]''

So you have a group of people, all adults, and probably badasses. Who will you leave in charge of the bunch? [[LargeAndInCharge Someone even bigger, more experienced, and tougher than they are]], right? Not this time--the leader is a person younger than all the rest, maybe even a kid. This usually shows that the young leader is smarter than his or her adult lackies, or that some manner of higher authority (usually their powerful parents) has placed them in charge. In any case, this usually makes for an interesting character dynamic.

Royalty fall under AChildShallLeadThem, while corporate versions are the GradeSchoolCEO. If a young leader (royal or otherwise) has established or expanded an empire, that's a YoungConqueror. A teacher in this position is PeerAsTeacher. If there are no adults, it's a TeenageWasteland.

[[folder:Anime & Manga]]
* ''Manga/{{Berserk}}:'' ChildMage Schierke is only about 13 by the Chapter of Elf Island according to the Official Guide Book, and yet most of the time she's the ''de facto'' leader of the party because she is wise and powerful beyond her years. Sure, Guts is the MagneticHero who attracted them together in the first place, and whose quest they're all a part of. But Schierke is the one who actually knows the way to their destination of Elfhelm, [[MissionControl coordinates everyone's combat]] through thought transference, and figures out a plan whenever they encounter some magical obstacle. Sometimes her youthful insecurity causes her to doubt herself, but when all's said and done her rational thinking and courage under pressure are what make her the rock whose stability everyone depends on.
* ''Manga/{{Bleach}}'':
** Hitsugaya is the Captain of the Tenth Division. He's a ChildProdigy with a biological age of approximately 12-13 years. Although he behaves far more maturely than children of his years would normally behave, it masks the obvious weaknesses of his young age. Aizen isn't fooled and exploits both the lack of emotional maturity and experience he knows Hitsugaya is hiding. This provokes a loss of self-control that leads to the defeat of every single captain opposed to him.
** Yachiru is the Eleventh Division Lieutenant. Although second-in-command of over two hundred warriors, her biological age is approximately 7-8 years. She tends to play up her youth and childishness and has a genuine SweetTooth that gets PlayedForLaughs. However, she's lieutenant for a reason; her power is phenomenal and when she becomes serious, she becomes dangerous. Even then, while her maturity is greater than a child of her years, it's never adult.
* ''Anime/CodeGeass'' has a 16 years old sub-Viceroy in season 1... A Viceroy as old as this in season 2... Someone who tells Zero he doesn't mind him being a student... Should we speak about empress of China? [[spoiler: Or [[Characters/CodeGeassLelouchLamperouge Emperor Lelouch?]] Empress Nunnally?]]
* In ''Manga/DeliciousInDungeon'', human knight and team leader Laios is the youngest member of the party after their encounter with the Red Dragon ended with them losing his younger sister.
* ''Anime/DoraemonNobitaAndTheTinLabyrinth'': The Hotel Burinkin is run entirely by ten-year-old Sapio and his alien bunny pet, Tap, due to Sapio's parents being abducted by the robot army led by Professor Napogistra. The Hotel itself is actually a front used by the human resistance to recruit allies for fighting against a RobotWar.
* ''Manga/FoodWars'': After the rebels win the Regiment de Cuisine against Central, Erina Nakiri becomes the new Dean of Tootsuki, at age 16 and while still midway through her first high school year. Somehow she manages to perform her duties smoothly while still continuing her own studies until she graduates, and then she becomes Dean full time.
* Situations like this arise occasionally in ''Manga/FullmetalAlchemist'', where [[HandicappedBadass Edward Elric]] is a fifteen-year-old [[ChildSoldier major]]; it becomes particularly noticeable when he interacts with Maria Ross and Denny Brosh, both of whom are adults and his underlings. Most of the series' adults take it in stride, though, since he's a TykeBomb and it's wartime.
* Loretta Cristiano is the head of the entire [[TheMafia Cristiano family]] in ''{{Manga/Gangsta}}'' at the age of 14, much to the shock of Alex, who initially assumes she's just a MafiaPrincess. Loretta is a tough cookie on her own who not only packs heat and knows how to use it but also gets help from her two [[BattleButler bodyguards]]..
* ''Manga/JoJosBizarreAdventureGoldenWind'' ends with [[spoiler:the fifteen-year-old Giorno Giovanna as don of [[TheMafia Passione]].]]
* ''Anime/{{K}}'':
** The 24-year-old Munakata, the Blue King. Even though he's an adult, he has power over just about everything in the government, and the Prime Minister resents him for this at his age.
** In TheMovie ''Anime/KMissingKings'', [[spoiler: 12-year-old Anna Kushina becomes the new Red King and leader of the infamous urban gang HOMRA]].
* ''Manga/KaguyaSamaLoveIsWar''
** One minor example is Kozue "Makki-senhai" Makihara. She leads Shuchi'in Academy's Tabletop Games Club as its "Dictator For Life" despite being a freshman, presumably having beaten the club's founder [[ConstantlyChangingName Terako/Gigako/Megako]] in a board game. She was also previously called "senpai" before losing the "pai" in a penalty game. To a lesser extent, there's also the KendoTeamCaptain Kojima, who won his position the same way.
** Hayasaka is the head servant for Kaguya's estate, as she's been working there the longest despite only being a teenager. Heavily deconstructed by a later chapter showing that her daily schedule is ''incredibly'' busy and stressful, to the point that her job explicitly violates child labor laws, but the Shinomiya family can get away with it thanks to their [[ScrewTheRulesIHaveMoney enormous wealth]].
* In the Battle City arc of ''Anime/YuGiOh'' who does Seto Kaiba appoint comissioner of the tournament? His elementary school aged brother Mokuba. Slightly deconstructed in that we see Mokuba can have his emotions on a subject manipulated by other kids (during Joey's duel with Espa Roba, where he ''could'' have stopped the whole duel due to Espa's cheating but was talked into not doing so, merely stopping the cheating from continuing) and one time he tried to call out a competitor for wanting a second rare card after a win, his authority was not taken seriously until Seto showed up.
[[/folder]]

[[folder:Fan Works]]
* ''Fanfic/AllAssortedAnimorphsAUs'': Near the end of "What if Tom was infested by a member of the Yeerk Peace Movement?", [[spoiler:Aftran is declared the new Visser One after Edriss and Esplin are killed. She shares the responsibility of leading the Yeerk army with Tom, who's only seventeen.]]
* In ''Fanfic/AvengersInfiniteWars'', when the Peter Parker of the fic's main reality (who has spent over a year fighting in the Clone Wars and bonded with a symbiote) becomes part of the events of ''WesternAnimation/SpiderManIntoTheSpiderVerse'', he basically becomes the leader of the assembled group of Spider-People despite Peter B and Noir being adults, as his experience with the Avengers has given him a broader range of experience and skills compared to most Spiders (another alternate Peter depicted is a Jedi with spider-powers, but he has less explicit experience than Peter).
* In ''Fanfic/TheConfectionaryChronicles'', Hermione is essentially proclaimed to be Loki's {{High Priest}}ess by Loki himself before her tenth birthday, as she has performed rituals and left him offerings for months out of true belief in him as her god, but she initially considers herself just a regular priestess as she's never thought about including anyone else in her worship. However, that changes when [[spoiler:Fleur Delacour joins Hermione in conducting a ritual so that Fleur can offer thanks to Loki for bringing Hermione into her life, this ritual basically affirming Hermione as a High Priestess of Loki with Fleur as her acolyte despite Fleur being the older of the two]].
* In ''Fanfic/DaphneGreengrassAndTheBoyWhoLived'', as well as being in charge of the 'Order of the Lightning Bolt' (the name of Dumbledore's Army in this continuity), during the search for the horcruxes Harry takes charge of a joint operation with members of the Order of the Phoenix [[spoiler:when planning the attack on Malfoy Manor]], although he admits in hindsight that he was just channelling the illusion of confidence.
* ''Fanfic/GodOfWarChainsOfTheHeart'': Despite only being, at most, 19 or 20, Skjöldr's been named the leader of his village and is quickly growing to become one of the primary leaders of Midgard in the aftermath of Ragnarök. According to him, it's due to his close friendships with gods and Jötnar, making him a natural spokesperson for his people. Freya also notes that, despite his youth, he has a strong charisma alongside a genuine talent for leadership.
* In ''Fanfic/TheOtherSideMemoriaeterna'', Peter Parker becomes the majority stockholder in Stark Enterprises after Tony Stark, Pepper Potts, James Rhodes and Happy Hogan was killed in the Snap (''Film/AvengersInfinityWar''). That said, Peter makes it his first priority to appoint suitable acting heads of the company's various departments as he recognises that he isn't experienced enough to actually lead the company himself, even if he makes it clear to all that Stark Enterprises will focus all viable efforts on finding a way to restore those lost to the Snap. Outside of Stark Enterprises, Peter's status as the HopeBringer also leads to him basically taking charge of the remaining heroes' campaign to restore the Stones and undo the Snap, with even Doctor Strange affirming that Peter Parker is the best of them.
* ''Fanfic/SpiderManFindingHome'' sees Peter post-''Film/SpiderManNoWayHome'' meet and form a polyamorous relationship with Kate Bishop, Yelena Belova, [[spoiler:Felicia Hardy and Shuri]], as well as forming a new team as they investigate various crimes in New York. However, it takes until Chapter 33 for Peter to realise that he's basically the team leader even if Yelena's the more experienced one, [[spoiler:Felicia]] observing that Peter's the one best suited to keep them all focused for reasons beyond him being the core of the relationship.
* Downplayed in ''Fanfic/ThievesCanBeHeroes''. Izuku is a first-year high school student, making him younger than his fellow phantom thieves, who are all second-year and third-year students with the exception of Morgana, whose [[MysteriousPast age is unknown]]. At the same time, he holds a certain level of seniority over them as the first to manifest his Persona.
* In ''Fanfic/WhatTomorrowBrings'', [[spoiler:the original timeline's Edriss is placed into Taylor's brain, and she still has the rank of Visser One, so the Yeerk invasion is being [[SymbioticPossession co-led]] by a teenage girl]].
[[/folder]]

[[folder:Films -- Live-Action]]
* The titular Chuck, from ''Film/AmazingGraceAndChuck'', is only 12-years-old but he starts and leads a global anti-nuclear weapon movement that begins with athletes going on strike in protest and eventually expands to include most of the other children in the world standing in solidarity with his vow of silence. By the end of the film, his movement has grown so influential that he's essentially able to ''veto'' a seven-year disarmament treaty between the USSR and the USA because its not good enough. He forces the two world leaders to go back and agree to total disarmament ''immediately''.
* While all of Film/{{The Avengers|2012}} are adults, their leader is the youngest (not counting [[HumanPopsicle time served as Capsicle]]) member, ComicBook/CaptainAmerica. And with good reason; the discussion over who's going to be running the show consists of Iron Man asking Cap to "call it", Cap laying out a flawless strategy to kill everything alien within a ten-mile radius with a maximum of efficiency and a minimum of casualties, and the rest of the previously-squabbling Avengers doing ''exactly'' as they are told without so much as a quibble.
* In ''Film/GhostbustersAfterlife'', when Trevor and Phoebe Spengler learn that their grandfather was one of the original Ghostbusters, Phoebe's scientific interests lead to her basically being the unofficial leader of the new team in Summerville as they [[spoiler:fight to stop Gozer reawakening]].
* ''Film/MasterAndCommander'' depicted very young midshipmen as naval officers (true to history).
* After Cain captured, his protege Hob becomes the leader of his drug gang in ''Film/RoboCop2''. Hob is a boy no older than 12.
* In ''Film/SpiderManNoWayHome'', when Peter Parker [[spoiler:joins forces with [[Film/SpiderManTrilogy two alternate]] [[Film/TheAmazingSpiderManSeries versions of himself]], he ends up becoming the "leader" of their temporary team as they battle their villains on the Statue of Liberty as the only one of the three Spider-Men who actually has experience in a team, as opposed to just being a constant solo hero]].
* The Vietnamese drug dealer boss in ''Film/TropicThunder'' is no older than 10.
[[/folder]]

[[folder:Literature]]
* ''Literature/{{Animorphs}}'':
** At the end of the series, the group finally went to the Army for help. The adult soldiers still ended up deferring to Jake, who was the Animorphs' leader and had way more experience with the Yeerks than they did. He was only sixteen at the time.
** It happened even earlier when the kids finally revealed their [[WakeUpGoToSchoolSaveTheWorld double life]] to their parents and forced their whole families into hiding. The adults were kept informed and asked for advice, but the kids made it clear they would act independently.
** A few years after the war, Jake is recruited by the US Army to train Special Forces teams in the use of morphing technology. {{Justified|Trope}} in that Jake legitimately is among the most experienced morphers in ''existence'', but he still remarks on how weird it is that full grown men, decorated military veterans at that, are saluting him and calling him "Sir".
* ''Literature/AscendanceOfABookworm'': At some point in the story, Myne ends up with a retinue of servants. Myne is seven years old by this time, the youngest of the servants is eight, and two out of the five servants are adults (older than fifteen for the setting's purpose). Later on, Myne gets put in charge of an orphanage, again with a few of the kids there being older than her.
* A subtle case in the first act of ''Literature/AClockworkOrange'', where fifteen-year-old [[SociopathicHero sociopath]] Alex is the youngest of his gang, and also their ruthless leader; this probably has something to do with the fact that he can single-handedly beat them all. Of course, his affinity for [[KickTheDog Kicking The Dog]] get him [[TheDogBitesBack betrayed in the long run]].
* Gifted young children in ''Literature/EndersGame'' undergo TrainingFromHell to become lead officers in the fleet. The protagonist Ender was age 9 when he became Commander of the entire fleet.
* ''Literature/FullMetalPanic'' has sixteen year old Teletha "Tessa" Testarossa as the commanding officer of a high-tech submersible carrier. The given justification is by her being a TeenGenius and a "Whispered" besides. Most of the "Black Technology" that went into the submarine came from the recesses of her brain and are ill-understood by others, making her an essential human resource to its optimal function.
* ''Literature/HiveMind2016'': Common in the Hive, because imprinting means that somebody may come out of Lottery fully prepared to run a research unit or be an administrator at age 18. Amber has a telepath unit at her beck and call at age 18, while Nicole is in charge of Amber's liaison team at age 19.
* ''Literature/TheSagaOfDarrenShan'': [[spoiler: Darren, a half-vampire who looks 12 even though he's actually about 20 years old at the time]] becomes a Vampire Prince, one of the five absolute rulers of the clan. This, for a position that a 120-year-old was considered too young for. But there are four other Princes -- their enemy clan has only one absolute Lord, and he's the same age as [[spoiler: Darren]].
* Most young leaders of groups in ''Literature/ASongOfIceAndFire'' get there by means of also being AChildShallLeadThem (any boy lord or boy king), or YoungConqueror (Daenerys Targaryen, along with a few in the history books). One of the only exceptions is [[spoiler:Jon Snow, Lord Commander of the Night's Watch]], who is voted to his position. His friend tells him that he's not the youngest (who was ten when voted in), but he's up there.
* The Pope (His Holiness Alessandro XVIII, 399th Pope) in ''Literature/TrinityBlood''. He's a 13 year old when he appears.
* ''Literature/TheUnwillingWarlord'': Sterren is around eighteen or nineteen when he's shanghaied into becoming the Warlord, [[spoiler:not much older for the following positions]], and ends up advising or ordering around people considerably older than him.
* Happens a couple times in the ''Literature/WarriorCats'' series. Scourge takes over the city cats when he's only a kit, simply because of his [[AsskickingLeadsToLeadership fighting skill]] and being the most bloodthirsty cat. In the first series, main character Fireheart is noted to be an extremely young leader; Bluestar made him deputy at a young age, and the warrior code states that deputy succeeds leader. If his training had taken the usual six-moons length, he would have been a warrior for only two moons at the age he became deputy.

[[folder:Live-Action TV]]
* In Season 2 of ''Series/The100'', the Ark survivors are theoretically led by their Chancellor, but it's teenager Clarke who forges an alliance with the Grounder army that's surrounded them, making her the Ark's ''de facto'' leader when dealing with the Grounders.
* Parodied in the ''Series/BlackadderTheThird'' episode "[[Recap/BlackadderS3E1DishAndDishonesty Dish and Dishonesty]]" where UsefulNotes/WilliamPittTheYounger is depicted as a [[ImprobableAge teenager]] who's appointed the [[UsefulNotes/TheMenOfDowningStreet Prime Minister]] "right in the middle of exams."[[note]]Real-life Pitt the Younger actually became youngest British PM ever at the ripe old age of 24.[[/note]]
* This happens a lot in the Franchise/DisneyChannelLiveActionUniverse:
** In ''Series/AustinAndAlly'', Ally (15) is head of the mall merchants' association, with no explanation given as to why.
** Logan in ''Series/ShakeItUp'' has the power to hire and fire employees at the [[BurgerFool kebab shop]].
** In season three of ''Series/KickinIt'', Jack has been hired as an instructor at the karate dojo. (Both characters played by Creator/LeoHoward, coincidentally or not.)
%%* Series/DoogieHowserMD to his staff.
* ''Series/TheFalconAndTheWinterSoldier'': Karli Morgenthau is the leader of the terrorist group called the Flag Smashers, despite the fact she is only a teenager.
* ''Series/GameOfThrones'':
** In season 6, Sansa and Jon petition [[BreakoutCharacter Lady Lyanna Mormont]] of Bear Island, the unexpected heir of the holding. She's quite in charge, taking no crap from anyone... and she's also just ten years old. She has the wherewithal to accompany her pledged soldiers to the Stark camp, gives Ramsay Bolton a withering DeathGlare when they parley before the battle, and when her side wins, she gives a room full of her fellow lords, all adult men, [[TheReasonYouSuckSpeech quite the dress-down]] for being [[FairWeatherFriend fair-weather friends]] to their ancestral lieges, [[RoyalsWhoActuallyDoSomething House Stark]], and then becomes [[spoiler:Jon Snow's kingmaker]].
** Due to being the highest-ranking person in Winterfell, Robb Stark has authority over a whole mess of experienced knights and retainers. Despite this, others underestimate him due to his youth. This dynamic is brought to the fore in "The Pointy End" when he calls his bannermen and begins to march south. In particular, it causes some tensions with Greatjon Umber but the Greatjon changes his mind when Grey Wind bites a few of his fingers off. Later, the Greatjon is the first in the Northern/Riverlands army to declare Robb as the King in the North.
** Bran Stark commands the respect of virtually everyone under his rule, despite being a crippled ten year old. After Robb died, he could be considered the true King in the North.
** When we see Cley Cerwyn, he seems barely out of his teens, but leading House Cerwyn.
* ''Series/{{Merlin|2008}}'' has got into this since Uther's death in season 4. Granted, Arthur is in his early 20s, but he's still younger than all of his knights and advisors and such.
* One episode of ''Series/StarTrekTheNextGeneration'' was about Wesley, 15 year old Acting Ensign, being given his first command position as leader of an away mission. Everyone else on the team were actual ensigns, much older than he and have already graduated from Starfleet Academy.
[[/folder]]

[[folder:Podcasts]]
* The Boyar Hermine is introduced in the prologue to ''Podcast/TheAdventureZoneEthersea'' as a "young girl" (it's unclear ''how'' young, but context suggests she's probably in her early teens) who is intelligent, of BlueBlood, and wields an incredible amount of charisma. This means it is quite easy for her to convince people to follow her, and she has a tendency to go behind the Council's back and do things her way. Over the course of the prologue, despite holding no official position in the government, she gains enough respect and influence in the community that she eventually is able to lead a non-violent coup against the increasingly-useless Council, with the support of not just one of the most respected men in the community, but much of the general populace as well.
[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/DarkChronicle'', the head researcher at Lunatic Wisdom Laboratory in Monica's time is Dr. Nobb, who looks to be about ten years old. According to him, Luna Lab is a strict meritocracy, where brainpower trumps age.
* The high lama of Angri-La from ''VideoGame/DragonQuestXI'' is a young boy. It was noted that many protested this choice initially but he has proven himself very capable.
* ''VideoGame/Fallout4'':
** The Brotherhood of Steel are led by "Elder" Arthur Maxson, who is a mere 20 years old. He seems to have ascended the hierarchy as a sort of return to form for the Brotherhood after the Eastern chapter's altruism and Western chapter's stubbornness saw the Brotherhood nearly annihilated. Maxson likely got the job because he is a direct descendant of the Brotherhood's founder, Roger Maxson.
** If the player sides with the Institute, Father will attempt to install the player as his successor. The player's age isn't hardwired anywhere, but the story assumes the player character is biologically within a year or two of having had their first child. The other members of Institute leadership are all in at least their fifties. Though this is possibly a subversion, since the player character spent 210 years as a HumanPopsicle and is technically older than any of them, including Father.
** Completing all the Minutemen quests will have Preston name the Sole Survivor as General of the Minutemen, most of whom appear decidedly older than the Sole Survivor. Of course, since Preston keeps giving you radiant quests after that and none of the other Minutemen even acknowledge their rank much less accept orders from them, they seem more like an AuthorityInNameOnly.
* By the time of ''VideoGame/FinalFantasyXIII2'', Hope (whose age ranges from 24-27) has become this. Each time you see him [[spoiler: even 400 years into the future]] he is the unquestioned Director of the Academy (and basically all of humanity by default). According to the prequel novel ''Final Fantasy XIII-2 Fragments Before'', Hope joined the Academy at 17 and became Director of it two years later at only 19 years old.
* ''VideoGame/FireEmblemPathOfRadiance'':
** Tormod is the leader of the Laguz emancipation army despite being somewhere between 12-14 when it forms, and only 15-17 by the time ''VideoGame/FireEmblemRadiantDawn'' rolls around.
** Sanaki is only ten years old (thirteen in ''Radiant Dawn'') and the Empress of Begnion, the largest country on the Tellius continent.
* ''VideoGame/{{GreedFall}}'' has three leaders, all fairly young for the positions they hold.
** De Sardet, at 23, is a Legate to the Congregation of Merchants and basically chief diplomat on the island of Teer Fradee.
** Their cousin, Constantin d'Orsay, is Governor of the Congregation city on the island, New Serene, at only 24 years old.
** Vasco, not even 25 years old, is Captain of his own ship. Furthermore, several people state he's been a Captain for several years at this point.
* Tetra in The ''VideoGame/TheLegendOfZeldaTheWindWaker'', a girl not much older than Link who leads a crew of pirates. It's explained that the adult pirates respect her for having taken on the captain's responsibilities at a very young age, following the death of her mother (their former captain).
* ''Videogame/LikeADragon:
** ''VideoGame/YakuzaLikeADragon'': Downplayed trope, but to rise to Governor of Tokyo at age 42 the way Ryo Aoki did is quite a feat. This was one of his strengths due to being younger and more charismatic than the typical elder statesmen of Japan.
** Daigo Dojima became [[TheDon Chairman of the Tojo Clan]] at the age of 30. In ''Like a Dragon'', he's actually the same age as Ichiban and Aoki.
* ''Franchise/MassEffect'':
** The player's original party members rise to increasingly higher positions of authority over the series due to their [[AsskickingLeadsToLeadership accomplishments]], making most of them an example because the squadmates skew unusually young, with most being in their early-mid 20s (or [[Really700YearsOld their species' equivalent)]]. The first game takes place in 2183, while Garrus was born in 2157 (making him 25-26), Ashley in 2158 (24-25), Tali in 2161 (21-22), and Liara in 2077 (105-106, but she herself says that's "barely more than a child" by her species' standards, and her social position, physical appearance, and mental development all appear consistent with a human in their early 20s). By the third game, three years later in-universe, they're respectively a general (or at least someone generals listen to and salute), a special forces colonel-equivalent, an admiral, and a crime boss of an NGOSuperpower. Joker was also born in 2155 (27-28), and though he doesn't get as high a formal position, he's still the AcePilot of his navy's most advanced warship (at the time).
** [[PlayerCharacter Commander Shepard]]'s formal rank of Commander (a colonel equivalent) is already an improbable rank for someone born in 2154 (making them 28-29 in the first game), but their [[AlmightyJanitor informal influence]] is more on the level of a general officer combined with a kingmaker politician. Also, since they [[BackFromTheDead don't experience]] the nearly two-year time skip between the first and second games, it's entirely possible that they end the series not having yet turned 30. Already absurdly young by real-world standards, made even more so by the fact that this takes place in a futuristic setting where a healthy human can live to 150.
* Major Ocelot in ''VideoGame/MetalGearSolid3SnakeEater'', aside from already being the rank of major, is in charge of an entire unit ''named after him'', and is a complete MagnificentBastard with ImprobableAimingSkills... at age 20.
* ''VideoGame/TheSecretWorld'': The head of the Dragon Faction is the Golden Child, a ten year old with prophetic powers. He has led the organization for centuries, and each time he dies the organization finds his reincarnation and re-instate him.
* Ion in ''VideoGame/TalesOfTheAbyss'' was named Fon Master (the equivalent of the Pope) before he was even twelve. Things get even more extreme when it's revealed that [[spoiler: Ion is actually a clone of the original Ion who died, making the current Ion mentally ''two years old''.]]
* ''VideoGame/VampireTheMasqueradeBloodlines'', due to its setting as a city where traditional vampire hierarchies aren't well-established, has a few examples:
** Gary Golden is the Primogen of the Los Angeles Nosferatu, and became a vampire about 40 years ago. For reference, 40 years as a vampire is the average age of a starting PlayerCharacter in [[TabletopGame/VampireTheMasquerade the tabletop game]].
** Gary's immediate superior [=LaCroix=], the Prince of Los Angeles, is about 190 and is noted to be unusually young for a Prince.
** Nines Rodriguez has barely 50 years under his belt as a vampire and is the 'leader' (or at least the public face) of the L.A. Anarchs. In his case it's justified, as Anarchs don't really care about seniority (or hierarchies at all). Nines is skilled, passionate and cool enough to make people want to join his cause and that's really all that it takes. It also helps that Anarch vampires traditionally do not live long due to being the weakest of the sects; making it to fifty when the Sabbat, the Kuei-Jin ''and'' the Camarilla all want you dead is downright impressive.

[[folder:Western Animation]]
* In ''WesternAnimation/AvatarTheLastAirbender'', [[spoiler: Zuko becomes the Fire Lord after wresting the position away from Azula during the Agni Kai, when he is 16 years old. The comics deconstruct this trope thoroughly as Zuko is still vastly inexperienced in the art of ruling.]]
* ''WesternAnimation/DinosaurTrain'': When the Conductor falls ill, his nephew Gilbert volunteers to take over conducting on the Dinosaur Train. Unfortunately, he keeps having to consult the manual due to his inexperience, and he's so short that he has to stand on top of a book and jump to pull down the projector screen.
* In ''WesternAnimation/TheSimpsons'' episode "Bart the Murderer", Fat Tony attempts to invoke this trope during Bart's trial for the murder [[spoiler: (actually, just the disappearance)]] of Principal Skinner. (Of course, it was Bart who was working for Tony.) The attempt backfires when [[spoiler: Skinner himself comes into the courtroom and explains that he had simply gotten trapped under a pile of his old newspapers while cleaning out his garage.]]
* Master Cyclonis, the EvilOverlord and leader of the Talons, from ''WesternAnimation/StormHawks'', who's only about the same age as the majority of the Storm Hawks (being in their teens). When she and Aerrow first meet, they're both surprised at how young the other is.
* ''WesternAnimation/TheTransformers:'' Hot Rod, upon becoming Rodimus Prime. Exact age is unclear, but Hot Rod is clearly quite young by Cybertronian standards, and even the burst of maturity that comes of becoming Prime doesn't exactly temper his brash nature. There's also the crushing responsibility of the role ''and'' the burden of having to replace Optimus Prime.

[[folder:Real Life]]
* UsefulNotes/AlexanderTheGreat was made a general at 18 and a king at 20. Though his authority was inherited, he very quickly proved his worth by proceeding to conquer the Persian Empire, one of the largest and most powerful nations in the world at the time. Imagine a college student steamrolling from northern Greece to India in an undefeated twelve-year campaign.
* We're not certain due to poor record-keeping back in those days, but the youngest person to become Pope was probably one of John XI, John XII, Gregory V, or Benedict IX. These four from the 10th and 11th centuries were somewhere in the 18-25 range when they were elected Pope (in Benedict IX's case, elected the first time).
* Luke Ravenstahl, mayor of UsefulNotes/{{Pittsburgh}} from 2006 to 2014, was first elected to the City Council in 2003 at the age of 23. Two years later he became President of the City Council, and when Mayor Bob O'Connor died in 2006, he became interim mayor. Ravenstahl won a special election the following year at age 26.
* Stevens T. Mason, the first Governor of UsefulNotes/{{Michigan}}, was elected in 1835 at the age of ''24''--too young to be elected to the federal Congress in Washington. As such, he was called "the Boy Governor", "The Young Hotspur", and "The Stripling", as well as other less-than-salutary nicknames when a border dispute with Ohio delayed Michigan's entry to the Union by a year.
* UsefulNotes/JoeBiden was elected to the US Senate thirteen days before his 30th birthday; 30 is the minimum age to serve in the Senate. Shortly after he took his seat, UsefulNotes/HenryKissinger mistook him for a staffer.
* UsefulNotes/JohnFKennedy and UsefulNotes/LyndonJohnson were 29 and 28 years old respectively when they were first elected to the House of Representatives. Kennedy was mistaken for an elevator officer multiple times early in his career.
* UsefulNotes/WilliamPittTheYounger first became [[UsefulNotes/TheMenOfDowningStreet Prime Minister]] at 24. He died in office during his second premiership at the age of 46.
* Compared to the American and Russian Revolutions, the generation of UsefulNotes/TheFrenchRevolution is unique for the fact that (mostly) men between their late 20s and late 30s ran it.
** UsefulNotes/LouisXVI was 20 years old when he became King, 34 when the Revolution started and 38 when he was killed. Georges Danton and Camille Desmoullins were in their early 30s. UsefulNotes/MaximilienRobespierre was 36 when he was killed. Louis Antoine de Saint-Just was 25 when he made his political debut and 26 when he was killed.
** Likewise, due to the dearth of senior officers (both because many of those promoted under Louis XVI had emigrated, and because the Republic's armies were massive compared to the previous royal army), many of the generals who fought the Revolutionary Wars were in their twenties. General Thiébault lampshades this in his Memoirs, saying that his own promotion to general at 30 was nothing exceptional at this time.
** UsefulNotes/NapoleonBonaparte was 26 and lacked experience as a commander-in-chief when he was put at the head of the Army of Italy.[[note]]The other generals, in particular André Masséna and Pierre Augereau who were more than ten years his senior and already had well-established reputations, did not appreciate being put under the orders of a "boy" like him, but they were soon forced to acknowledge that he was not half bad himself.[[/note]] He became Emperor at the age of 33.
* UsefulNotes/MuammarGaddafi took control of UsefulNotes/{{Libya}} through a coup d'état in 1969 when he was around 27 (his birthdate is unclear).
* Kim Jong Un took over as the dictator of UsefulNotes/NorthKorea after the death of his father in 2011; according to domestic sources, he was less than a month shy of his thirtieth birthday at the time,[[note]]Other sources claim that he was born either one or two years later.[[/note]] making Jong Un the current world's youngest state leader.
* The 2011 Canadian federal election saw many ridings that had traditionally voted Liberal or Bloc Québécois change over to voting NDP (the so-called "Orange Crush" had the NDP gaining a net sixty-seven seats from the last election, in 2008). It's fairly common practice to field younger, less experienced candidates in ridings where they're not expected to win, and apparently even the New Democrats themselves were a bit surprised by how many of their new [=MPs=] weren't even thirty when they took their seats (whereas only one NDP MP younger than thirty had gotten elected in 2008). The riding of Sherbrooke elected the first ever teenage MP in Canadian history, NDP candidate Pierre-Luc Dusseault, who noted later that he had planned to work at a local golf course for his summer job. (Dusseault had his twentieth birthday days before the 41st Parliament was called.)
** In another example of this trope from the opposite end of the political spectrum that same year, Andrew Scheer (who himself had been a Conservative Party MP since 2004, when he was twenty-five) was elected speaker -- that is, final authority -- of the House of Commons less than two weeks after his thirty-second birthday. Although Scheer lost the speakership with the Conservative government's defeat in 2015, he would play the trope straight again by getting elected leader of his party one week after his thirty-eighth birthday in 2017.
* In 2018, Alexandria Ocasio-Cortez was a 28-year-old bartender and waitress, just four years above the minimum age to run for the United States Congress (she was 29 when she took office), when she scored a major upset victory in the Democratic Party primary against Joe Crowley, who represented New York's 14th Congressional District and was considered one of the leading figures in the party. The fact of her age, combined with her upset of Crowley and her reputation as a left-wing populist firebrand, made her one of the most high-profile figures in the Democratic Party even before the ForegoneConclusion that was the actual election (New York's 14th being stridently Democratic-leaning), and was immediately seen as the ''de facto'' leader of a group of four newly-elected left-wing Congresswomen known as "the Squad" even though she was the youngest of them by seven years.
** Two years later in the other major party, 25-year-old Madison Cawthorn, a real estate firm owner from North Carolina, defeated army veteran Moe Davis in a bid to represent the state's 11th District. Taking office just five months older than the cutoff age, he was the youngest serving politician to have a seat in a major office in the United States government. However, he lost his primary come the following election and only served one term in the House.
* UsefulNotes/MikhailGorbachev was a relative example of this when he became the leader of [[UsefulNotes/SovietRussiaUkraineAndSoOn the Soviet Union]] in 1985. Being 54 years old at the time, he was not young as such, but he was the youngest member of the Politburo.
