->"''All wars are Civil Wars, because all men are brothers.''"
-->-- '''Francois Fenelon'''

A Civil War is an intense conflict between organized groups trying to take control of a state and/or region, or to change government policies. Most Civil Wars are fought by a status-quo ruling body of the state and one or more groups that wish to change said state, though said non-state groups often fight each other as well, and it can also be between two states that both claim to be the sole rightful (nation-)state for a single nation. To be considered a "war" rather that an uprising or rebellion requires that the conflict involve regular armed force, involve organized factions, and be on a certain scale and of a certain intensity. All the sides involved have to have a genuine chance (however small) of achieving their aims in the conflict for it to be a Civil War and not just a rebellion/uprising. Where rebellions end and Civil Wars begin often isn't clear, and whether a conflict is called one or the other often depends on what the factions - especially the victorious one - [[InsistentTerminology decide to call it]].

Those fighting Civil Wars usually don't call them that, as they try to make use of [[YourTerroristsAreOurFreedomFighters the power of language to suggest that they are in the right]]: the ruling power will term it a police action against unpopular extremist rebels. Their enemies will consider themselves People's Heroes and Freedom Fighters spearheading a populist Revolution. However, it is just as likely for a small group of rebels to claim Civil War status (as such terminology would give their struggle an air of seriousness it would not otherwise have), or likewise, for the government to use the term (to justify force that would seem excessive against a mere criminal action). How the outside world views the situation is largely WrittenByTheWinners. This is largely why wars for independence are so murky when it concerns the concept: generally, if a country fails to gain independence, expect it to be called a civil war, and if it does, expect it to be called a regular war or a Revolution (thereby implying that the two post-war countries were never one).

No matter who prevails, it is often a PyrrhicVictory, as, depending on the world situation, internal conflict provides an opportunity for exploitation or conquest by outside forces: DivideAndConquer if the villain takes advantage, and EnemyCivilWar for the heroes.

Civil Wars both real and fictional have provided excellent opportunities for stories, as depicted morality can be all over the board. The fact that both sides believe themselves to be justified allows for an authorial portrayal of [[RousseauWasRight both sides having good people fighting for what they believe in]] along with [[TheGoodTheBadAndTheEvil a couple of real bastards on both sides]]. Often, while one side may indeed be presented as morally superior, there will be a WorthyOpponent among the enemy ranks and the PerspectiveFlip is common. Along with that, there can be StarCrossedLovers pining for each other across the battlefield and families split by the tension of what they believe is right.

Many an AlternateHistory is based around one side of a Civil War prevailing over another.

This is not to be confused with Creator/MarvelComics' ''ComicBook/CivilWar''.

'''Examples of factual Civil Wars commonly used in media:'''

* The UsefulNotes/WarsOfTheRoses (1455-1485), famously depicted in Shakespeare's plays.
* The UsefulNotes/EnglishCivilWar(s) (1642-1651) looms large in British wargaming and historical re-enactment, but also some dramas
* UsefulNotes/TheAmericanRevolution (1775-1783) is under-represented, but still features in US works
* UsefulNotes/TheAmericanCivilWar (1861-1865) features in US works
* The [[RedOctober Russian Civil War]] (1917-1922) features prominently in Soviet works and expat accounts, most famously in Sholokhov's epic novel ''Quiet Flows the Don''
* The [[NoMoreEmperors Chinese Civil War]] c.1916-1950 is a setting for a smattering of mainland-Chinese dramas and several foreign sinophiles' diaries
* The French Civil Wars in [[WorldWarTwo 1940-44]] and [[{{UsefulNotes/Algeria}} 1954-62]] are conspicuously ''absent'' (bar Film/TheBattleOfAlgiers) - official policy under UsefulNotes/CharlesDeGaulle was that [[FanonDiscontinuity the former never happened]], and the same has largely gone for the latter as well
* The UsefulNotes/SpanishCivilWar (1936-1939) is the inspiration for Picasso's ''Guernica'' and features in the writings of Creator/GeorgeOrwell and Creator/ErnestHemingway
* The UsefulNotes/KoreanWar (1950-1953) is perhaps best-remembered as the setting of M.A.S.H. and some forgettable action-flicks
* UsefulNotes/TheVietnamWar (1955-1975) is very well represented in US media, albeit featuring largely (if not exclusively) on the US's involvement.
* UsefulNotes/TheTroubles (1969-1998) are at least in the background of many works set in the British Isles in the '60s-'90s, although as with the British Civil War of 1916-21 and Irish Civil War of 1922-23 ''direct'' focus on the events is very rare
* The Main/SriLankanCivilWar (1983-2009) is hard to avoid in local media
* [[http://en.wikipedia.org/wiki/List_of_civil_wars And a host of others.]]

!!Examples of famous fictional Civil Wars:


[[folder:Anime & Manga]]
* The Gryps War of ''ZetaGundam''

[[folder:Comic Books]]
* ''{{ComicBook/Asterix}}'' provides the page picture (although the names aren't those of the Goth chiefs but doctored to be the names of then-current French politicians). Astérix, Obélix and Getafix engineer an EnemyCivilWar berween the Goths to prevent them from invading Gaul before ''centuries''.
* The Marvel ''ComicBook/CivilWar'', with heroes supporting a SuperRegistrationAct fighting those who refused to reveal their identities. Intended to be an OutsideManInsideMan situation, with the pro-reg group trying to head off an even worse situation by co-operating.
** The resulting Fandom War, pitting the authors of said story arc versus most of the rest of the fandom.
*** And [[WriterRevolt their fellow writers]].

* In [[FanFic/EquestriaAHistoryRevealed Equestria: A History Revealed]], the Equestrian Civil War, when Luna first became Nightmare Moon and attempted to usurp Celestia.
* Depending on your interpretation of [[http://www.fimfiction.net/story/90939/1/shell-shock/the-tower the backstory of Shell Shock]], the conflict may or may not be a civil war.
* Heavily implied to be the case in [[http://www.fimfiction.net/story/88520/1/welcome-to-the-brothel/das-laufhaus Welcome To The Brothel]].
* In FanFic/AKingdomDivided some of Equestria's towns rebel against Princess Celestia.
* In [[http://www.fimfiction.net/story/129154/brother-against-sister Brother Against Sister]], it's Prince Blueblood who leads the seceded part of Equestria. Apparently, ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic writers love this trope.
* Occurs ''twice'' in Venezuela before the AlienInvasion in ''FanFic/WorldwarWarOfEquals''. First between various political factions after [[spoiler: Hugo Chavez's death]] and the second between [[spoiler: Loyalist forces and supporters of the new military leadership after Nicolas Maduro is removed from power by a military coup]].
* ''Narrowly'' averted in the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''[[http://thejboy88.deviantart.com/gallery/44076506/MLP-The-Divide The Divide]]''. After it's discovered that [[spoiler: Sombra was Celestia's son]], Cloudsdale secedes from Equestria in disgust, with rumblings as far as the Crystal Empire of others planning the same. However, despite Chrysalis' [[FalseFlagOperation attempt to inflame the situation]], cooler heads prevail, and ultimately the situation is resolved peacefully, with Cloudsdale rejoining.
* Much like in the [[Literature/ASongOfIceAndFire books]], FanFic/SonOfTheSevenKingdoms has a civil war, but the number of sides is smaller: the main contendants are Joffrey (who holds the Iron Throne and has the support of the Westerlands) and William (with the support of the North, the Riverlands, Dragonstone and part of the Stormlands), while Renly and the Tyrells seek to ally with William (who is betrothed to Arya Stark) by marrying him to Margaery, Dorne and the Vale are proclaiming neutrality and the Iron Islands might end up becoming independent.

* The Galactic Civil War within the [[TheEmpire Galactic Empire]] forms the central conflict of the ''Franchise/StarWars'' franchise, preceded by the Clone Wars, [[DoesThisRemindYouOfAnything fought between]] the Galactic Republic and a Confederation formed for seceding Republic planets. Numerous smaller-scale civil wars are noted in the Franchise/StarWarsExpandedUniverse, and initially the Empire cracked down on them fiercely, unlike the Republic which usually let them be or sent Jedi to figure things out. Later the Empire was content to let them rage while chasing Rebels.
** In the EU there's actually a ''Second'' Galactic Civil War, this one with the Galactic Alliance (post-NewJediOrder New Republic, which in itself is post-Endor Rebel Alliance) against the Confederacy, which is a group of worlds led by Corellia in an attempt to break away. It ends up shifting the power balance quite a bit; the Jedi Order even forms its own temporary government in order to end the conflict.
* The Franchise/MarvelCinematicUniverse has a civil war between loyal agents of SHIELD and infiltrated agents of Hydra. It begins in ''Film/CaptainAmericaTheWinterSoldier'', and it is continued in ''Series/AgentsOfSHIELD''.

* A civil war is an important part of the backstory in ''Literature/ABrothersPrice''. The royal family of Queensland had such a wealth of daughters that the family was split, the older half staying and marrying Michael, the younger half marrying Raphael and moving to rule recently-annexed Southland. But Michael turned out to be infertile, and the younger sisters became more and more insistent that their children be considered the heirs. This led eventually to what was called the War of the False Eldest, which ended with all of the younger sisters and their children being executed. Except, it turned out, for their boy Alannon, who was [[AMatchMadeInStockholm abducted by Queensland spies]]; he is dead by the time of the book, but the RoyalBlood he passed on certainly has an impact on his grandson.
* Most of ''Literature/ASongOfIceAndFire'' is devoted to this. They start calling it The War of the Five Kings in the second or third book. In the BackStory there are more, such as the Dance of the Dragons, the Blackfyre Rebellions[[note]]except for the last, the War of the Ninepenny Kings. By that point Blackfyre support in Westeros had been exhausted enough by the repeated failed rebellions that the only open Westerosi supporters during the war were exiles, and the war never actually reached Westeros proper[[/note]] and Robert's Rebellion.
* Literature/{{Discworld}}'s Ankh-Morpork has a number of Civil Wars in its backstory, though the narrator makes clear that many were accidental, overblown in the retelling, and generally not very competent affairs. It is mentioned that while the Patrician, [[MagnificentBastard Lord Vetinari]], has created a time of relative peace under his rule, he has done so by playing increasingly small factions against each other, to the point where, although everyone is technically still fighting a civil war, no one can do enough damage or make enough money out of it to become a threat. The Night Watch books in particular utilize the concept.
* Literature/DonQuixote travels to Barcelona, a Spanish province that is at a CivilWar at TheCavalierYears
* The Wizarding Wars of ''Literature/HarryPotter''. Presumably Voldemort had his eye on global conquest, but the books focus on his attempts to fully consolidate power in Britain, and those fighting against him from within.
* The HanoverStuartWars in ''Literature/{{Waverley}}''.
* Literature/ForWhomTheBellTolls is set during, and about, the SpanishCivilWar.
* In ''Literature/ChristianNation'', a dozen or so American states that are in protest of President Steve Jordan enforcing the Fifty Blessings to be the law of the land, superceding the power of the Constitution, attempt to secede, forming the Secular Bloc States, leading to what was called a "holy war" which ultimately ends with the rogue nations being recaptured and the last holdouts of freedom and democracy being laid siege upon in Manhattan.

[[folder:Live Action TV]]
* Two of them on ''Series/BabylonFive'': The Earth Alliance Civil War, and later the [[spoiler: Minbari]] Civil War. Several other civil wars are indicated or implied to happen off-screen after the show's end, such as the Telepath War on Earth and Vir's rebellion against Emperor [[spoiler: Londo Molari]] on Centauri Prime.
* [[Series/DoctorWho The Dalek Civil War in]] ''[[Recap/DoctorWhoS25E1RemembranceOfTheDaleks Remembrance of the Daleks]]''.
* The Unification War in the backstory of ''Series/{{Firefly}}'', by virtue of its intended analogizing to the UsefulNotes/TheAmericanCivilWar.
* The fight of the Federation against the Maquis in the ''Franchise/StarTrek'' franchise veers from this to portraying them as merely a terrorist group, DependingOnTheWriter.
* ''Series/{{Supernatural}}'':
** Season 6 involves a civil war in Heaven, as the CouncilOfAngels fragments after season five's ScrewDestiny ending. On one side, ArchangelRaphael and those who think the Apocalypse should be restarted. On the other, Castiel and those he's convinced to try this "free will" thing. There's plenty of spillover onto Earth, although most of it is left to our imagination. [[spoiler: It gets so bad Castiel is willing to work with Crowley, then give up on free will altogether and declare himself the new God after absorbing the souls of Purgatory. This ends badly.]]
** In Season 9 the remaining angels are all thrown out of Heaven and sent to Earth. Soon multiple factions are fighting a nasty civil war amongst themselves over what the angels should do next. Angels who prefer to remain neutral are hunted down and killed by all the warring factions. There is also a civil war going on in Hell as the Demon Knight Abbaddon has returned and challenged Crowley's position as King of Hell.
*** Comments from Castiel's former followers in Season 7, as well as Metatron in Season 8, suggest that the fighting never actually ''stopped''. It's just that the spillover doesn't reach Earth again until the angels fall in mass at the end of Season 8.

[[folder:Tabletop Games]]
* The HorusHeresy is one of the biggest setting-defining events of ''TabletopGame/{{Warhammer 40000}}'', despite the fact it took place ten thousand years ago in the past. This is due to the fact that the war was ''so'' devastating that it resulted in the deaths of trillions, caused the Emperor to essentially die, and cost the Imperium thousands of years of technological innovation, transforming it into a FascistButInefficient dictatorship/theocracy, besieged on all fronts by hostile forces and stuck in MedievalStasis.
* Happens frequently in ''TabletopGame/BattleTech''. The Free Worlds League tend to be at civil war with each other from time to time, and the Clans don't always agree with one another and fight each other just as often during their Invasion. Then there was the [=FedCom=] civil war instigated by Katherine Steiner-Davion for control over two states.
* The primary setting of ''[[{{TabletopGame/FateOfTheNornsRagnarok}} Fate of the Norns: Ragnarok]]'': an eternal winter has set in, the end of the world approaches, and Viking society collapses: cue lots of civil wars for what's left.

[[folder:Video Games]]
* ''VideoGame/BioShock1'' have Rapture's Civil War with Hero's [[spoiler: see it's aftermath of final days]], [[spoiler: While ''VideoGame/BioShockInfinite'' have thier two heros see thorugh of first days of Columbia's civil war in third alternate timeline that alternate Booker became 'matyr' and that is main turning point of civil war started.]]
* ''VideoGame/DragonAgeII'' shows the beginning of a civil war between the mages and templars which could potentially spread across the world. The player is forced to choose a side, [[GreyAndGrayMorality which is more difficult than it sounds.]] The conflict is more widely depicted in ''VideoGame/DragonAgeInquisition''.
** The [[VideoGame/DragonAgeOrigins first game]] also contained a conflict between Loghain and the Ferelden nobility.
** As of ''Literature/{{Asunder}}'' (which takes place shortly after II), civil war is also on the horizon in the Orlesian Empire, the most powerful human nation in the setting. This will be detailed in ''Literature/TheMaskedEmpire''.
** One of the [[AwfulTruth Awful Truths]] revealed about the elves in ''VideoGame/DragonAgeInquisition'' [[spoiler:is that this is how the original elven homeland was really destroyed.]]
* In ''VideoGame/TheElderScrollsVSkyrim'', there's a civil war raging between the [[FantasyCounterpartCulture Imperial]] [[TheRomanEmpire Legion]] and the [[FantasyCounterpartCulture Stormcloak]] [[HornyVikings rebellion]]. [[PlayerCharacter You]] can negotiate peace between the two sides (on account of the pressing threat of the entire world getting eaten by dragons), or join up with one. (Or negotiate peace, then join up with one side and end the war anyway.) The civil war itself is a sterling example of GreyAndGrayMorality and BothSidesHaveAPoint in action, neither side is "right" and both sides have negative elements:
** The Empire is trying to hold onto Skyrim because it needs both the resources and the manpower, especially since they expect a full-scale war with the Aldmeri Dominion in the future. Skyrim also acts as a vital transportation hub, connecting the heart of the Empire to all of its other territories. While the Empire is criticised for not understanding the people of Skyrim or their cultures, they are generally considered fair and just rulers by the common citizens. However, the Empire's vast bureaucracy and weak leadership clog their government with inefficiency.
** The Stormcloaks view the Empire as an oppressive foreign power that is weak and unfit to rule Skyrim, and are violently opposed to the Empire's ban on the worship of the human god Talos (a clause that was reluctantly added to the peace treaty the Empire signed with the Thalmor). However, the Stormcloaks carry a noticeable degree of FantasticRacism against non-Nord races, and their rebellion is perceived by many as ill-timed and short-sighted, especially in the face of the true threat of the Thalmor.
** The entire war was instigated by [[spoiler:the Aldmeri Dominion. The Thalmor's intent was to soften up the Empire for another invasion attempt, though they realize they may have underestimated Ulfric. The Dragonborn getting involved and quickly ending the war in favor of either side will completely derail this plan since it means the Thalmor will either have to face a united Empire or a two front conflict against the Empire ''and'' Skyrim. The only truly "wrong" choice for the Dragonborn is to do nothing.]]
* The Covenant Civil War in ''{{Halo}}'', started in the last year of the Human-Covenant War when [[BigBad Prophet of Truth]] thought that the [[ProudWarriorRaceGuy Sangheilis]] had [[YouHaveOutlivedYourUsefulness outlived their usefulness]] and tried to extinct them with the help of the [[KillerSpaceMonkey Jiralhanaes]]. Didn't worked so well when the Sangheilis [[EnemyMine allied with the Humans]] and destroyed the Covenant as a superpower.
* In ''VideoGame/MassEffect3'', the RobotWar between Quarians and the Geth [[spoiler:was actually spawned by a Civil War between Quarians who sympathized with the Geth and Quarians who wanted to destroy them all. The Geth only took up arms to defend their friends, but this eventually became "defend themselves" when the quarian sympathizers were rendered into a non-entity.]]
* The backstory for ''VideoGame/StarTrekOnline'' reveals that this is pretty much the state of affairs for the Romulans [[Film/StarTrekNemesis post-Shinzon]] that got worse [[Film/StarTrek post-Hobus Supernova]]. The backsotry dealt with the war between Tal'Aura's Romulan Star Empire and Donatra's Imperial Romulan State in the aftermath of Shinzon's rebellion while the main bulk of the Romulan Player Character deals with Sela's Romulan Star Empire (ran by the Tal Shiar) going up against D'Tan's Romulan Republic.

[[folder:Web Original]]
* After the takeover of Molossia (now ''WebVideo/{{Kickassia}}''), the people of ChannelAwesome fracture over the spoils, resulting in one of these: WebVideo/TheNostalgiaCritic against everyone else.
* One of these ended a dynasty in the [[Wiki/TheWorldbuildProject Acasi Empire]], which in turn ended [[WarIsHell a twenty-year war between the empire and the neighboring city-states of Rhael]].

[[folder:Western Animation]]
* The war for Mobius on the ''WesternAnimation/SonicSatAM'' cartoon.
* In ''Franchise/{{Transformers}}'' in general, the default state of Cybertron seems to be a state of civil war to provide a reason for robots to shoot each other. There have also been various internal conflicts within both Autobot and Decepticon, and occasionally Maximal, Predacon, and Vehicon ranks.
* Book 2 of ''WesternAnimation/TheLegendOfKorra'' looks to be about one between the Northern and Southern Water Tribes.
