Young Conqueror

""The only person with whom I felt any kinship with died three hundred years before the birth of Christ. Alexander of Macedonia, or Alexander the Great, as you know him. His vision of a united world... well, it was unprecedented. I wanted... needed to match his accomplishments, and so I resolved to apply antiquity's teaching to our world, today. And so began my path to conquest. Conquest not of men, but of the evils that beset them.""

- Adrian Veidt, Watchmen

Youthful idealism can be a beautiful thing. There are few things audiences love more than the idea of a gifted teenager (or sometimes simply a young adult) who can see what's wrong with the world and, after initially feeling overwhelmed and powerless in the face of a Crapsack World, deciding that they need to do something about it.

In some cases, may obtain or be born with some special power to help them achieve their goal. Whether they do or not, the key difference between the Young Conqueror and The Hero is that instead of fighting crime on a case by case basis or having to face an already existing Big Bad, they have a much bigger vision and will try to Take Over the World in a belief that Utopia Justifies the Means. However, if these ideas are already a quick way for adult characters to go merrily Jumping Off the Slippery Slope, being a young, frustrated rebel, complete with the standard emotional immaturity and sometimes flat-out childish fantasies you'd expect out of someone this age only makes things worse. Consequently, they often end up as a Well-Intentioned Extremist and end up on the Sliding Scale of Anti-Heroes, unless they are a(n) (Anti)Villain Protagonist.

In addition to differing from the typical hero in vision - or ends - they will also differ in the means used. In contrast to the Idiot Hero, the Young Conqueror will have a strong dose of Intelligence Equals Isolation, which may cause them to be quite prideful. And instead of a typical hero who reacts to the nefarious plans of the Big Bad and fights with brawn, they are a Guile Hero who uses brains to come up with their own schemes, often being either The Chessmaster, Manipulative Bastard, Magnificent Bastard, Mary Tzu, or all of the above, capable of cooking up a Xanatos Gambit or Gambit Roulette just as good as or possibly better than your standard Big Bad. As such, they are often subversions or inversions of The Villain Makes the Plot, which is one of the main reasons why these characters are so unique and interesting.

If they're targeted by bullies, expect them to later gloat Who's Laughing Now?, though when they realize the extent of the damage they've caused, they're especially prone to wondering My God, What Have I Done? and going through a Heroic BSOD and/or Heel Realization, assuming their Ubermensch mentality cracks enough to let them see it. These characters often die young, seemingly "burned out" by their own genius, though a Young Conqueror who lives to adulthood can either continue down their path to Anti-Villain status (or sometimes simply become The Big Bad, deluded by their own idealism), or they can become a Mentor who issues Jacob Marley Warnings to other youngsters in their former position.

In a way a variant of Rags to Riches. A milder and hopefully less bloody version found in the commercial rather then politico-military sphere is the Self-Made Man. When this is Recycled in Space, it is likely to be Galactic Conqueror.

When Young Conqueror is done with his conquests, he may settle down to being The Emperor. If he does it fast enough, he'll be Young and in Charge.

Anime & Manga

 * Death Note: all of the four main characters have the mental qualifications to be this, but only Light is idealistic enough to follow this route.
 * Code Geass: Lelouch vi Britannia.
 * Monster: a story where the main villain, Johan, has all the qualifications, but rather than changing the world, wants to destroy it, just because he can. Unlike For the Evulz types who want to watch the world burn, he doesn't seem to get much satisfaction out of the horrible things he does: he just wants to set it on fire. And is very good at it.
 * Naruto has Pein/Nagato, who learned ninjutsu in his youth with his True Companions and afterwards started a group with them to create a better world and was given the Rinnegan. After being forced to kill his best friend, he commits bloody vengeance on his betrayers and plans to create a super-weapon that will scare the other villages into stopping all war.
 * Legend of Galactic Heroes: Reinhard von Lohengramm is a textbook example. Luckily he has Kircheis to watch his back, both physically and morally.
 * Akumetsu. He acts like a goofy Idiot Hero, but he is actually very cunning and resourceful. He is also much more physical than other examples of this trope.
 * The protagonist of Lost Brain.
 * Shinobu Sensui, in contrast to Yusuke Urameshi. Is a pretty brutal Knight Templar as a Spirit Detective and wants to Kill All Humans as a villain- seeing as his idealistic black-and-white worldview did a 180 since he was on the side of good (pre- Face Heel Turn he thought all humans were good and all demons were evil, as the Big Bad he thinks the opposite).
 * There seem to be a few characters in Revolutionary Girl Utena who seem to fit this... but not the eponymous Utena, who is just rebellious on a personal level.
 * Star Driver has the Glittering Crux as an entire organization led by these, though for now the only one to have shown definite proof of belonging here is Kanako, a teenager who plays the Stock Market like a fiddle (and who is an Olympic level boxer... as well as a damn hot chick).
 * Prince Maximiliam from Valkyria Chronicles, an ambitious 29 year old imperial general.
 * Griffith from Berserk in the Golden Age arc, before he became a demonic god.

Comic Books

 * The title character of the DC Comics series Prez: Prez Rickard, 18 year old President Of The United States.
 * Adrian Veidt/Ozymandias from Watchmen, Alexander's fanboy wants to conquer the evils of mankind, he also builds a business empire from scratch and pushes his body and mind to perfection.
 * Tony Stark before becoming Iron Man was a business version of this; he was also a drunken playboy. In Civil War he gets back on the conquering horse.
 * Hunter Rose aka Grendel, genius writer by day and hitman by night, takes control of a criminal empire spanning from Atlanta to Montreal with NYC at the centre.

Fan Fiction

 * Shinji and Warhammer 40 K elevates Shinji to this trope.
 * In Harry Potter and the Methods of Rationality, Harry is very much this trope, and can't really understand why no one's tried to take over the magical world with a working knowledge of scientific principles in the past.

Film

 * The title character of the film Charlie Bartlett.
 * Michael Corleone in The Godfather
 * Not that young but Tony Montana from Scarface climbs to the top of the drug dealing community almost as fast.
 * Howard Hughes in The Aviator conquers the film and aviation industries, world aviation records, Cate Blanchett and Kate Beckinsale but never his fear of germs.

Live Action TV

 * The title character in the Korean serial epic Jumong.

Literature

 * Dune: Kwisatz Haderachs Paul Atreides and God-Emperor Leto Atreides. Probably Trope Codifier.
 * In Harry Potter, Voldemort, Dumbledore, and Grindewald are hinted to have been this, for a start.
 * Peter Wiggin in Ender's Game. The Ender's Shadow series details his rise to power as Hegemon of Earth.
 * Thomas Cale in the Left Hand Of God seems to be evolving into one of these.
 * The A Song of Ice and Fire series has had a few of these.
 * One such figure that a number of characters admire is a past Targaryen King is known by the moniker "The Young Dragon" and managed to do what all the Targaryens (even those with dragons at their be beck and call) had failed to do; conquer the Kingdom of Dorne. An older and more cynical character points out that trying to actually hold Dorne, however, took up an ungodly amount of resources and resulted in many casualties, since the Dornish prefer insurgency anyway. When the Young Dragon died young, Dorne almost immediately threw his armies out and reclaimed their independence.
 * Daenerys Targaryen shows herself rather adept at conquest, completely destroying Slaver's Bay and the slave trade. However, she quickly learns that while she may have a knack for conquest, actually ruling these places whose societies she upended is a far greater challenge.
 * The trope, specifically in the example of Alexander the Great, is harshly criticized in Jonathan Wild by Henry Fielding. Wild, a historical figure who controlled London crime in the mid 17th century is presented as a great admirer of Alexander, and this admiration is because Alexander was a murderer, thief, and rapist, but since the Rape, Pillage and Burn was on a grand scale, people think of him as a hero. Wild hopes that in his own small way, he can become a sufficiently powerful criminal that he will be thought of as a Great Man.
 * In The Count of Monte Cristo, Luigi Vampa, a celebrated bandit, is analogized to one of these, because he's achieved power and celebrity and is not yet 30. Vampa may be aware of the comparison, since he likes to read Julius Caesar for fun.
 * The backstory of Mackenzie Calhoun from Star Trek: New Frontier.
 * The backstory of Mackenzie Calhoun from Star Trek: New Frontier.

Religion

 * Jesus Christ in his Second Coming, according to Biblical prophecy. This is probably the only example that (at least from a Christian perspective) is actually desirable.

Video Games

 * Darth Revan in Knights of the Old Republic. Revan was a Jedi prodigy whose peerless strategy won the Mandalorian War for the Republic, and nearly won the Jedi Civil War for the Sith. S/he built up quite the Evil Empire before being betrayed in the traditional Sith manner, and is respected and/or feared throughout the Galaxy. All of this  before about twenty-five to thirty.
 * The player´s character in the second installment of the Overlord series is a very dark version of this trope.
 * The Player Character in Fable III can be played as a Young Conqueror, following in the footsteps of their same-gender parent (the Player Character of Fable II) who rose from a broke orphan raised by Gypsies to become Monarch of Albion, largely though shrewd Real Estate purchases.
 * JC Denton in Deus Ex; a cyberpunk variation, note the Meaningful Name (or initials).
 * In the Dynasty Warriors game, Sun Ce (see below) always plays this trope to the hilt. His personal campaign usually details how, if he had avoided his historic early death, he would have gone on to unite China himself.
 * Meanwhile, in Samurai Warriors, Masamune Date tends to play this role - young, brash, respectless, immensely talented and ambitious. Interestingly, the historical Masamune Date was both closer to, and further from, this ideal.
 * In Sengoku Basara, Masamune plays much the same role, only he's actually got the charisma to make taking over the country achievable. Ieyasu is a more humble and idealistic example who's more interested in making the country a better place than just lording it over everyone else.
 * In Fallout: New Vegas, Caesar of Caesar's Legion was once this, having founded the Legion at around 21, though he's in his fifties by the time you meet him.
 * Gulcasa in Yggdra Union and Blaze Union, though rather than having the standard prideful Ubermensch personality he's a Messianic Archetype driven by PTSD. He becomes emperor of Bronquia at age 17, deems continental conquest to be the most efficient way to destroy societal prejudice, and in the canon end of the games dies at age 20 after ruining his health and losing all of his loved ones to his own wars. In Yggdra Unison, where it's possible for him to succeed, he settles down as a benevolent world leader after making his ideals reality.

Real Life

 * In general this was much more common in ancient times, when the sons of aristocracy would often receive their military training through direct battlefield experience at ages younger than what we would consider the norm for adulthood. This often went hand-in-hand with Asskicking Equals Authority.
 * Napoleon Bonaparte (borderline: he wasn't a teen anymore, but he became a general at 24, and was only 30 when named First Consul of France).
 * Alexander the Great: He became a military commander at the age of 16, became king and began his conquest of the known world at the age of 20, and died emotionally and physically burned out at age 32 with his plans completely unfinished with no successor to leave them to.
 * In something of a variant of this, Alexander was in fact being groomed to be a conqueror by his father who was a Magnificent Bastard in his own right.
 * Evariste Galois... for the world of mathematics at least.
 * Charles XII of Sweden. Ascending the throne at 15, Denmark-Norway, Poland-Saxony, and Russia formed an alliance against Sweden to take advantage of his youth. Charles surprised everybody by holding his own and then outright invading and conquering the first two members of the alliance, winning an outnumbered victory against the Russians (and almost killing Peter the Great) in the process. He got greedy fighting in Russia, however, and was beaten decisively at Poltava.
 * Genghis Khan came to be this going from being a Noble Fugitive, nearly alone on the steppes with his mother to being The Scourge of God.
 * Glorious Leaders seem to always pretend to follow this trope even if they've never fought a war in their entire lives. As modern warfare is too bureaucratized for this, this image becomes something like Miles Gloriosus.
 * During the Three Kingdoms Era of China, Sun Ce - founder of the Kingdom of Wu - fits this trope. He was known as the 'Little Conqueror' because of it - taking control of the prestigious Sun-family after the death of his famed father, Sun Jian, when he was barely out of his teens - and with skill and courage, seizing vast quantities of land. (Sadly, he died young as well. So it goes...)
