History Main / AHouseDivided

* ''LightNovel/{{Baccano}}'': The alchemists aboard the ''Advenna Avis'' were already divided in conflict before they received their elixir of life. Immortality should've resolved most of their disputes and rendered the rest futile to continue. But the gifting demon left an escape clause in case they tired of eternal life; they could absorb each other to take all their knowledge and experience. They quickly figured how this might be used against each other.

* In ''Literature/{{Gate}}'', it seems that the Empire isn't in complete control of their lands, as seen in episode 2 when the Emperor orders his allied nations to get slaughtered by the new enemy forces occupying their gate. He later orders the surrounding regions to undergo a SaltTheEarth policy, officially to deny the JSDF from obtaining local resources. But secretly it's meant to further quell any rebellious mood against the Empire.

* ''LightNovel/{{Schwarzesmarken}}'': This is practically the theme of the entire series. Taking place in an alternate timeline where Asia acquired an army of alien bioweapons (with no context as to whether or not Asia survived), the armies of East and West Germany are still at civil war with each other by the division made from their factions, and are willing to greatly decrease humanity's chances of survival (and even their own) if it means that they can send their rivals' entire armies into a meat grinder of Eldritch Aliens.
* In ''Literature/SwordArtOnline'', the party that Diabel attempted to put together in Episode 2 nearly falls apart due to his friend Kibaou being very mistrustful of beta testers. After they defeat the first floor boss, the hard-earned celebration is cut short by Kibaou, who accuses Kirito of indirectly causing Diabel's death and again calls for a witch hunt of beta testers. Realizing the rift that Kibaou was causing, Kirito attempts to have them channel their hatred towards him instead and acts as the TokenEvilTeammate so as to not have the players start fighting amongst themselves.
** In ''Progressive'', the group of players who took down the first boss split into two factions, one headed by Kibaou and one headed by Lind. Kirito and Asuna, who are not aligned with either group, are forced to proceed with caution to avoid upsetting the delicate balance of power between the two groups or allowing tensions to escalate into outright conflict.

* The lighthugger ''[[CoolStarShip Nostalgia For Infinity]]'' in ''Literature/RevelationSpace''. Despite having a crew of ''six'' ([[ManInTheMachine seven]] if [[HumanPopsicle you're generous]]), almost the [[SpacePirates entire crew]] hate each other's guts and are willing to murder each other. The only two characters that get along are [[CyBorg Hegazi]] and [[IceQueen Volyova]], or Volyova and [[ActionGirl Khouri]]

Subtrope of DividedWeFall. May be caused by an ArtifactOfAttraction or other AppleOfDiscord. Compare GoldFever (greed may cause infighting) or NoHonorAmongThieves (lack of loyalty may sink villains' plan because they can't work together). When this erupts into a full-scale war, particularly within a country, you have a CivilWar.

* Not uncommon in ''VideoGame/AmongUs'', where the presence of [[TheMole impostors]] slowly killing members of the crew makes the good guys extremely suspicious of each other. [[MiscarriageOfJustice Innocents may be executed]] by the crew via majority vote, which directly helps the impostors accomplish their goal of [[KillEmAll killing them all]].

* In the ''Series/{{Angel}}'' episode "[[Recap/AngelS04E06SpinTheBottle Spin the Bottle]]" when the cast were regressed to their 17-year-old versions and trapped in the hotel. They all belong to the types listed in the header: Angel (MartyStu), Gunn (BaldBlackLeaderGuy), Fred (DistressedDamsel), Cordelia (DamselScrappy by that time), and Wesley ({{Jerkass}}).

* The Trolls from ''Webcomic/{{Homestuck}}'' eventually become this, as shown by [[http://www.mspaintadventures.com/?s=6&p=005221 this update]] and the ones following it. They start off with twelve. Currently, they're down to four (five and a half if you include Aradia and Sollux), and Kanaya expresses an interest in making it three.

* In each of the main ''Franchise/{{Danganronpa}}'' games, Monokuma informs the students that the only way to escape from the ClosedCircle they're in is to [[DeadlyGame murder one of the others without getting caught]]. On top of this, [[TheCorrupter he gradually introduces extra motivation]], leading to more paranoia as nobody can be sure who's going to try and get out. However, after the fourth of fifth chapters in each game, the tropes stops being into play with a final group of surviving students who work together to defeat the mastermind behind Monokuma and escape the place.

* In ''VisualNovel/DanganronpaTriggerHappyHavoc'', the villainous headmaster Monokuma informs his students that the only way to escape Despair Academy is to [[DeadlyGame murder one of the others]] without getting caught. On top of this, he gradually introduces extra motivation, leading to more paranoia as nobody can be sure who's going to try and get out.

The opposite of LockedInARoom: the ensemble of diverse characters starts to argue and turn against each other during intense situations. E.g. being boarded up in a house/building/store when there are rampaging [[TheVirus viruses]] / [[ZombieApocalypse zombies]] / [[AlienInvasion aliens]] / [[OurVampiresAreDifferent vampires]] / [[OurWerewolvesAreDifferent Werewolves]] or what have you [[TheSiege looming outside]] ([[TenLittleMurderVictims or inside]]) [[SuperPersistentPredator trying to get to you]]. Which leads to paranoia, frustration, and disagreement among the group when it comes to fixing the dilemma. Patience starts to run short, the ensemble is starting to get on each other's nerves, and things quickly get out of hand and possibly implode.

* ''Roleplay/{{Kyuupiikei}}'': Trapped in a situation where someone could kill at any time, the students begin to distrust and turn against one another.

* Happens regularly in ''TabletopGames/BattleTech'', the five great houses generally have infighting among themselves from time to time. The most prominent example is House Marik, which broke up into four factions after the Jihad. The Clans also have this a lot, they are divided into two groups the Crusaders, and the Wardens who have conflicting views on Kerensky's legacy.

* Marvel's ''Comicbook/CivilWar'' arc has caused this among its heroes.

* The {{Jerkass}}... obviously.

* ActionGirl, who probably resents the Damsel.

** Inverted with the Fatal Five's Trial in ''Film/SawV'', in which Jigsaw meant for the victims to work together through the hints he gave them as a lesson for their selfishness. Too bad the victims were so determined to act this trope out straight...

* ''VideoGame/DarkestDungeon2'' replaces the affliction mechanic of the first game with relationships. Should two characters form a bad relationship, they will constantly bicker and pettily try to sabotage one another. This ranges from dealing stress, preventing skills, and debuffing one another. Amusingly, sometimes one of them gains stress when the other is attacked because ''they hate them that much''.

** And then in ''The Blood of Olympus'' [[spoiler:the actual union between the campers is sidelined to the point where it has literally nothing to do with the conflict against Gaea and the giants.]]

** In ''Film/SawII'', this happens with the victims of the Nerve Gas House game, although not between all of them at once:

*** Everyone turns against Obi once they find out that he assisted Jigsaw in kidnapping most of them. Likewise, all of them except Amanda turn against Daniel when they realize that he's the son of Eric Matthews, a corrupt detective who arrested them for numerous crimes they weren't responsible for.

*** Xavier progressively gets angrier with the other victims until he decides to leave them after the antidote in his game (which he had Amanda do for him) ends up locked. Once he finds out that each digit of the code to unlock the safe at the starting room is written on the back of each victim's neck (including himself), he tries to kill everyone in order to get the antidote for himself.
