A broken base is a civil war among fans of a particular franchise. Almost every franchise has at least some internal conflict among its fanbase, but a truly broken base is characterized by a sustained and exceptionally vicious conflict between two or more large, vocal, and entrenched factions with little or no middle ground to be found between them.

Common causes of a broken base include [[ShipToShipCombat shipping wars]], a large and vocal PeripheryDemographic whose priorities are at odds with the main demographic, or [[BaseBreakingCharacter a divisive character]], [[ContestedSequel sequel]], [[TheyChangedItNowItSucks adaptation, or remake]].

Contrast FandomHeresy for a fandom opinion that is near-unanimous to the point where it tends to silence any dissent.

''When adding examples, please keep in mind of the following:''
* ''It is a sustained conflict that has fans debating a work or subject. Upcoming works cannot be this since such conflicts are considered to be short-lived by definition. Such examples can be placed under TaintedByThePreview.''
* ''It is a vicious conflict: bringing up the subject will likely result in a huge debate among fans.''
* ''It has at least two large factions, not merely one VocalMinority against a SilentMajority. Each side has a noticeable amount of supporters. In addition, the fanbase must be large enough to support the factions. An obscure work is less likely to have a broken base than a very famous one or a broad subject.''
* ''It is divisive: most fans hold a strong opinion on the subject. There is very little middle ground.''

''All four criteria must be met to qualify. Minor disagreements don't count.''

* ''Film/{{Doctor Strange|2016}}'': The casting of Creator/TildaSwinton as the Ancient One has been divisive. While many are glad to have a powerful character be portrayed by a female actor, especially one as accomplished as Swinton, others are upset that the original Tibetan version wasn't used, mostly because the MCU had yet to feature a heroic Asian person in the films.[[note]]The first performer of Asian descent to get BilledAboveTheTitle for an MCU movie, ''Film/GuardiansOfTheGalaxy'''s half-Filipino [[Wrestling/{{Batista}} Dave Bautista]], did so for playing an alien, Drax the Destroyer.[[/note]] Co-writer C. Robert Cargill's comments on it being done to prevent the movie from being BannedInChina due to a potential positive portrayal of a Tibetan character (which the studio itself later denied) added more controversy. He also didn't help things by accusing all the people upset over it of being "social justice warriors", though he later backpedaled on it and said everyone absolutely has the right to have issues with it.

* ''Literature/HarryPotter'': Creator/JKRowling declaring [[WordOfGay Dumbledore to be gay]] shortly after the release of the final book is something that ''everyone'' in the fanbase has an opinion on, and to this day is a hot topic among the base. The two main camps are those who feel that the character's orientation is fairly well-supported in the text, with the WordOfGod being merely a confirmation of something that a close reading could have already revealed, versus those who feel that it's either a cheap way for Rowling to drum up conversation about a closed book or to quiet complaints about a lack of gay representation in the series or both.
