* Even more than its original series, ''Fanfic/CodeGeassMegiddo'' is [[ForWantOfANail based around the premise]] that Julius Caesar's invasion of the British Isles was repulsed by the [[BadassArmy armies of]] [[DarkMessiah Alwyn]], resulting in [[TheEmpire Britannia's]] ultimate foundation and the world that followed. And that's before one takes a look at [[MagicalEye Geass']] implementation [[AncientConspiracy throughout history]], which is very much akin to the Pieces of Eden from ''Franchise/AssassinsCreed''.

** And the main ForWantOfANail that sets the premise of the fic, is the USS Enterprise damaging IJN Yamato enough in the Kure Raid that she was unable to participate in operation Ten-Go, leading to her capture by the Americans. Years later when Admiral Halsey was unable to get support to retire Enterprise as a museum ship, he made a deal with the General [=MacArthur=]: He helps the general in convincing the government to refit Yamato and formally add her into US Navy, and in return the General will help him in convincing the Japanese to buy Enterprise as a precaution against the Communists. They succeed, and Yamato became USS Montana, while Enterprise became JDS Yonaga, whose long service with JMSDF earned the titular nicknane Eien, Eternity.

* ''FanFic/TheConversionBureauTheOtherSideOfTheSpectrum'' does this to one [[WesternAnimation/MyLittlePonyFriendshipIsMagic Equestria]] (called the [[TheEmpire Solar Empire]] or [[MirrorUniverse TCB!Equestria]]). There are [[CrypticBackgroundReference often numerous differences mentioned between the]] (mostly) canon universe and the TCB one, such as [[TheGreatOffscreenWar genocidal purges of the Changelings and a war with the Crystal Empire]]. There's also the existence of totem-proles (a surveillance network similar to [[Literature/NineteenEightyFour telescreens]]) and the genocidal war against humanity. [[ForWantOfANail All of which came about]] because [[spoiler:TCB!Lyra Heartstrings decided to go off on a little scuba diving trip with her buddies and uncovered a little ArtifactOfDoom that turned Celestia into its BrainwashedAndCrazy puppet ([[PointOfDivergence Prime!Lyra on the other hoof denied the invite to practice for the Canterlot Royal Orchestra tryouts]])]]. Whoops.

Whoops.

* In ''Fanfic/AllAmericanGirl'' and ''[[https://www.youtube.com/playlist?list=PL62BA69EAB6DBD807 Ed, Edd n' Eddy Z]]'', 9/11 never happened. In the former's case, al-Qaeda also never existed.

* ''Fanfic/AThingOfVikings'' takes the first ''WesternAnimation/HowToTrainYourDragon'' film and drops it, anachronisms and all, into Real Life History in the AD 1040s as the point of Divergence, with the worldbuilding essentially being designed around dragons having existed [[InSpiteOfANail but not having an impact on world history]] until Hiccup tamed them and brought the dragons of the Green Death's nest into his tribe. Now, in 1041 AD, where the height of military technology on the planet is Greek Fire, a small Norse tribe in the British Isles has a fire-breathing ''air force''. Hijinks ensue.

** "Lady Liberty" is set in a world based on a game of ''VideoGame/{{Civilization}}'', and features the Mongols as Britain's great enemy in Asia. Also, the Statue of Liberty in this world is in Edinburgh, and is actually [[spoiler: a [[ForcedTransformation transformed]] [[WesternAnimation/DannyPhantom Dani]]]].

* In The Geeky Zoologist's [[Fanfic/JurassicWorld2020 reimagining of Jurassic World]], there is a minor example. In the universe of this fic, Rolando Araya Monge became president of Costa Rica instead of Abel Pacheco and attended the inauguration of Jurassic World.

* In ''Fanfic/{{Emperor}}'', a ''Literature/HarryPotter'' fanfic, history changes when Robert Schuman fails to convince the European governments to work on what would eventually become the European Union, leaving the continent divided, Britain militarized and the threat of war hanging over everyone's heads. [[spoiler:Turns out that the failure of [[AtomicHate Project Manhattan]] was an even earlier point of divergence.]]

Whoops.

* ''Fanfic/KhanVictorious'' is a a Star Trek timeline that explores a universe where Khan Noonien Singh and the Augument’s were able to win the Eugenics Wars, through the use of a last ditch tactic which ensured their victory: engineering a genetic virus, known as the Ascension Flu, which results in any future children born infected with the virus to be born as Auguments. From there it explores the consequences of that change upon the Star Trek universe.

* The ''Fanfic/HogwartsExposedTimeline'' on Website/AlternateHistoryDotCom posits the impact of the events of the ''Literature/HarryPotter'' books happening in our world... and exposed to the public in the late 1990s.
* ''Webcomic/HetaliaAxisPowers'' has a good deal of alternate histories and universes within its collective. One notable, though dark, example is ''Fanfic/AllHeEverWanted''
** The ''Fanfic/NineteenEightyThreeDoomsdayStories'' is a BroadStrokes AlternateUniverse crossover series between ''Webcomic/HetaliaAxisPowers'' and ''Literature/NineteenEightyThreeDoomsday,'' history diverging in 1983 when the UsefulNotes/ColdWar turned into a catastrophic nuclear hell. The stories are told entirely through the eyes of the Nations themselves, more specifically those around what had been Central Europe.
** ''[[http://www.fanfiction.net/s/5842533 This is Justice]]'', ''[[http://www.fanfiction.net/s/6547779 Blind Carbon Copy]]'', and ''[[http://www.fanfiction.net/s/5640188 Grey Skies Over London]]'' involve timelines where America lost the [[UsefulNotes/TheAmericanRevolution revolution]] against England. Most similarities end there though, as they each take completely different paths after that point.
** ''Fanfic/ACastleOfSilenceAndBones'' takes place in world where the Axis Powers not only won UsefulNotes/WorldWarII but had also taken over much of the planet at gunpoint. [[CrapsackWorld Things get]] [[FromBadToWorse much worse]] from there.
** ''Fanfic/MonarchyOverTheDanube'' involves a timeline where the Habsburgs return to Austria in 1935, resulting in a reborn Austria-Hungary and a changed world.
* ''Fanfic/BattlefieldGallia'' is essentially a UsefulNotes/WorldWarII story that imagines the world of ''VideoGame/ValkyriaChronicles'' existing alongside ours. For the Axis, Allies and Soviets, at least, things get weird ''very'' quickly.
* It's not the focus of the story, but there is a Watchmen fanfic where [[PhysicalGod Dr Manhattan]] is monologuing about various alternate incarnations of himself he is aware of, with one world having a noteable divergence in the past, where "It is Mithraism that becomes the driving force of western civilization, and the people of the city we know as New York wear golden bulls around their necks, and it is Christianity that lies forgotten in the dusts of history."
* ''Fanfic/TheSonOfTheEmperor'' is basically what happens when you combine UsefulNotes/TheNapoleonicWars with ''WesternAnimation/MyLittlePonyFriendshipIsMagic.'' Historical hijinks and world-changing events ensue.
* The ''Fanfic/{{Uplifted}}'' series are about what happens when the Quarians decide to uplift Humanity in order to bring an end to their exile and retake Rannoch. Unfortunately, Russia in 1942 might not have been the best place for first contact. In the second part of the story, the Quarians begin to collaborate with the Junkers in order to bring down Hitler's government. Also features a love story between a Quarian and an SS officer. It's rated M for a reason, the author is not shy about showing just how racist the average person was back then, or any of the other nastiness of that war.
* In ''Fanfic/AllAmericanGirl'' and ''[[https://www.youtube.com/playlist?list=PL62BA69EAB6DBD807 Ed, Edd n' Eddy Z]]'', 9/11 never happened. In the former's case, al-Qaeda also never existed.

* In ''Fanfic/TheConversionBureauColdWar'', a xenocidal Princess makes contact with humanity to announce how she plans to wipe them out... in [[UsefulNotes/ColdWar 1986]], to the leaders of [[BullyingADragon the world's most powerful nations]].
* ''Fanfic/StrikeWitchesQuest'' has said witches exist in history with minor effects with major ones occuring as a Martian invasion hits at the same time as Pearl Harbor, resulting in the countries of the world uniting to fight back. One of the side effects of the invasion is most of the nefarious leaders/powers are removed either by the Martians or by others taking advantage of the situation.
* ''Fanfic/{{Pokeumans}}'' claims that the original Neanderthal humans lived alongside creatures that we would recognise today as Pokemon, until [[HumansAreBastards they started abusing their privilege and companions]]. This one [[TheFourthWallWillNotProtectYou could have actually happened, though - eventually the Legendaries undid everything they taught humanity and all evidence of their existence before leaving for a different dimension.]] This then has repercussions in the modern day - BIG repercussions.
* In ''[[Fanfic/TheLastWarWorldWar3 The Last War]]'' by Jan Niemczyk, the democracy movements east of the Iron Curtain are crushed by the USSR and loyalist forces. A renewed Cold War simmers on until April, 2005 when it finally boils over. There are no battlefield nukes any more, so [[WorldWarIII World War III]] does not go nuclear in the first hour after the bullets [[MoreDakka and pretty much everything else]] start flying.
* In ''Fanfic/ImGivingYouANightCall'',[[spoiler: As a Post-Conqueror of Shamballa verse,]] this is to be expected. In that story the first Edward and Alphonse Elric were prominent figures in the Second World War and defused the tension of the Cold War and implied to have had a hand in the creation of their world’s Amestris.
* ''Fanfic/PacificWorldWarIIUsNavyShipgirls'' has UsefulNotes/TheKoreanWar begin and end differently, namely the US Seventh Fleet being wiped out at the beginning thanks to an AlienInvasion. Additionally, it has France secede from NATO in the 1960s, as well as a more militaristic (and less economically successful) Japan, and finally a less influential United States.
* ''Fanfic/{{TITANOMACH}}'' sees the world take a ''very'' different turn after WWII, with America, the Soviet Union and China choosing to form a non-aggression pact to focus on bringing the rest of the world under their direct control. This pact (the Triumvirate) remains standing several decades later, when the Traveler arrives over Mars.
* The ''VideoGame/KanColle'' fic ''Fanfic/{{Eternity}}'' has a naval portion of WWII go a little differently:
** Directly inspired by ''Fanfic/IndestructibleSpirit'', due to politics the ship that was to become IJN Kongou stayed in England and became HMS Indestructible. Thus Hiei became a lead ship of her own class, and somewhere down the line the Japanese decided that they in fact did need a 4th battlecruiser, so they built it and named her Kongou. Something the [[ReplacementGoldfish shipgirl did]] [[StuckInTheirShadow not appreciate]].
** Hood was captured instead of sunk, which had driven Churchill into frenzy and directed many efforts to sink her despite the navy's resistance. Attempts to sink her failed, but the British got back at Germans by capturing Bismarck instead. Both survived the war, and after the brief return to their original countries' service they transfered to their "captors'" navies as symbols of European solidarity.
** And the main ForWantOfANail that sets the premise of the fic, is the USS Enterprise damaging IJN Yamato enough in the Kure Raid that she was unable to participate in operation Ten-Go, leading to her capture by the Americans. Years later when Admiral Halsey was unable to get support to retire Enterprise as a museum ship, he made a deal with the General [=MacArthur=]: He helps the general in convincing the government to refit Yamato and formally add her into US Navy, and in return the General will help him in convincing the Japanese to buy Enterprise as a precaution against the Communists. They succeed, and Yamato became USS Montana, while Enterprise became JDS Yonaga, whose long service with JMSDF earned the titular nicknane Eien, Eternity.
* ''Blog/ThePredespairKids,'' in addition to being an AlternateUniverse for ''Franchise/{{Danganronpa}}'', has quite a few historical deviations from our own. Hope's Peak Academy was founded back in 1937, Toranosuke Ishimaru served as the 46th prime minister of Japan instead of Noboru Takeshita, and the Towa Group and Togami Corporation managed to save Japan from experiencing the economic downturn in the 1990's, leading to the country becoming a much more important player in world politics. However, some things remain consistent between worlds, such as Brexit and the 2016 U.S. Presidential Elections.

* ''Fanfic/AThingOfVikings'' takes the first ''WesternAnimation/HowToTrainYourDragon'' film and drops it, anachronisms and all, into Real Life History in the AD 1040s as the point of Divergence, with the worldbuilding essentially being designed around dragons having existed [[InSpiteOfANail but not having an impact on world history]] until Hiccup tamed them and brought the dragons of the Green Death's nest into his tribe. Now, in 1041 AD, where the height of military technology on the planet is Greek Fire, a small Norse tribe in the British Isles has a fire-breathing ''air force''. Hijinks ensue.
* In ''Fanfic/FadedBlue'', Steven tells Lapis there are 194 countries- two fewer than in real life. This is because Russia doesn't exist, and Korea never split into two countries.

* ''Fanfic/AlwaysAdvancing'' has Yukari Akiyama, the loader of [[Characters/GirlsUndPanzerOaraiAcademyAnglerfishTeam Oarai's Panzer IV]] in ''Anime/GirlsUndPanzer'', wake up in an alternate timeline where her school was never was able to revive its Sensha-do program and subsequently shut down. The story follows her attempting to [[Main/PuttingTheBandBackTogether locate where her old Oarai comrades are]] while being part of the Sensha-do team at her new school, Saunders.

Also, the Statue of Liberty in this world is in Edinburgh, and is actually [[spoiler: a [[ForcefulTransformation transformed]] [[WesternAnimation/DannyPhantom Dani]]]].

* The ''VideoGame/KantaiCollection'' fic ''Fanfic/{{Eternity}}'' has a naval portion of WWII go a little differently:

* In ''FanFic/AeonEntelechyEvangelion'' history starts to diverge in 1930, when the discovery of the Elder Thing City (which causes the USA to drop its Isolationist policy and join the League of Nations) and the prolonged World War II (The War ends in 1946 with the atomic bombing of Berlin by the western allies to deny the Russians).
* Many [[AfterActionReport AARs]] on the ''VideoGame/TotalWar'', ''VideoGame/{{Civilization}}'' and ''Paradox series inevitably result in alternate histories of varying types.

* ''Script/NeverAgain'' revolves around a future in which World War II and the Holocaust never happened... and succeeds in NOT using HitlersTimeTravelExemptionAct. How do they do this? [[spoiler: By redeeming all the Nazis, AND HITLER, in one ''heck'' of a HeelFaceTurn.]]

** Katherine Parr never marries ''any'' of her historical husbands, electing to go to court instead and become one of Anne's companions. There, she meets Henry Howard, the Earl of Surrey, falling in love and marrying him instead. Their marriage tempers him, and the two become Duke and Duchess of Norfolk after the death of Thomas Howard.

* ''Blog/ThePredespairKids,'' in addition to being an AlternateUniverse for ''Franchise/{{Danganronpa}}'', has quite a few historical deviations from our own. Hope's Peak Academy was founded back in 1937, Toranosuke Ishimaru severed as the 46th prime minister of Japan instead of Noboru Takeshita, and the Towa Group and Togami Corporation managed to save Japan from experiencing the economic downturn in the 1990's, leading to the country becoming a much more important player in world politics. However, some things remain consistent between worlds, such as Brexit and the 2016 U.S. Presidential Elections.
