Alternate Histories in webcomics.
- Word of God in author notes for And Shine Heaven Now reveal that the Millenium invasion caused this to happen, though she never worked out many of the details beyond Bill Clinton dying in office during the invasion, Gore taking office and winning in re-election, and increased security measures meant that 9/11 never happened. Oh, and vampires and zombies never became 'trends' cause so many people were affected by the invasion. So, on the bright side, no Twilight.
- She also notes that this is an alternate universe in the sense that the Doctor has another planet as his favorite, as opposed to Earth in canon.
- A.P.O.C is set in London, 2045. The history alternates somewhere between 2018-2020, where Brexit gets ridiculously out of hand and forces the UK to dissolve, and England to become a semi-isolated country that's dilapidated. Also four children are experimented on by scientists, forcing their bodies to harness the Four Horsemen of the Apocalypse, so there's that.
- Blood is Mine: At first, the comic seems to be set in our world 20 Minutes into the Future. However, the characters mention that super-powered mutants first appeared during World War II.
- Collar 6 was revealed to be this. The point of divergence was when the Roman Empire discovered the ruins of Atlantis.
- Speaking of George Lucas, Darths & Droids takes place in an Alternate History where the Star Wars films were never made and instead the plot was used as an RPG campaign.
- Darths & Droids is part of a growing genre started by DM of the Rings, which all have this trope as a basis. See Campaign Comic.
- This trope is taken to extremes (and routinely extended) here
.note
- Dreaming Of Utopia takes place in an alternate version of The '90s where Furries are a Religion instead of a Fandom. They first appeared partly as a reaction to the First World War.
- El Goonish Shive presents us with a glimpse into one, in which the Uryuoms made public contact with Earth as far back as the American Revolution. One character, who has memories of that timeline, remarks that she's utterly screwed in this world's history class because of it.
- Girl Genius takes place in a world more or less like our own in the 1800s or so, except for the presence of 'Sparks' — natural mad scientists who are compelled to build amazing technological wonders and pretty much rule the world- not very well mind you. There's at least one Spark who's noticed this and is trying to wipe out the rest (though he's understandably considered Ax-Crazy and not the hero). The storyline of the comic is theorised to be their world's equivalent of the Napoleonic Wars with Klaus Wulfenbach in the Napoleon role.
- Also it is hinted that the Queen of England is some kind of undead or at least immortal creature/machine, and that something happened in the Americas at some point in the past to make them effectively inaccessible.
- Hotblood! is an alternate Earth where humans and centaurs live side-by-side. This trope comes in because some historical figures have been replaced with centaur equivalents.
- Least I Could Do Once had a storyline about Rayne writing an Alternate History book about Nazi Germany, though the main Alternate History thing about it was the Self-Insert Fic part.
- The Paul Reveres is a weird historical war comic set during the American Revolution, where all the historic battles are fought in a Battle of the Bands format, with the American militia represented by one band, The Paul Reveres, while the British are represented by The Union Jack-offs.
- Word of God is that Questionable Content takes place in a worrld where the space program didn't go into the crapper after Apollo resulting in technology spinoffs including AI robots as a common part of society, cyborg limbs and a privately owned space station think tank.
- Radioactive Panda makes a throwaway joke about how George Lucas suffered a fatal heart attack in 1993; the characters lament that they "only" got to see Spielberg's vision of the prequel trilogy, which won 14 Oscars.
- In The Red Star, a widow from an alternate Soviet Union recounts their defeat at the hands of an alternate Afghanstani. With Magitek.
- In Roswell, Texas set in 1948 Davy Crockett survived the Alamo, assassinated Santa Anna and used his influence to keep Texas an independent nation. A running gag is historical figures with very different life stories. Just a couple of examples: Meir Kahane, Malcolm Little (Malcolm X) and George Lincoln Rockwell are all Texas Rangers. Walt Disney is President For Life of California with Marion Michael Morrison (John Wayne) as his Army Chief of Staff
- Rumors of War takes place in a Bronze Age world similar to our own where the Trojan War was not one, but three, separate known-world-spanning affairs the left a Scavenger World in its wake. A Wizard Did It.
- Templar Arizona takes place in, to quote the author, "a slightly irregular Arizona that fell off the back of a truck somewhere, and now all the power outlets are a weird shape and a couple of wars never happened." Specifically the titular town exists on what in our world is the Navaho Reservation, there is or was a guerilla war going on in Australia between the government and the natives and both Greco-Roman and Egyptian Mythology have a bigger cultural background presence.
- Twice Blessed is set in an alternate version of our world, where history was changed drastically at some point when magic was discovered by "Archmage Plato".
- Westward takes place in a universe where World War II ended with the destruction of Berlin (and, incidentally, much of Europe) by a (presumed) Soviet superweapon. The Cold War continues into the 21st century, a manned mission to Mars happened in 1974 with attempts to colonize it made by the 1980s, and Faster-Than-Light Travel is possible in 1999 (though no-one entirely understands how it works). Because the webcomic's plot ultimately spreads to other universes, other Alternate Histories may be encountered as well.
- xkcd: "Alternate History" discusses how, if alternate history stories can have their own Show Within a Show alternate histories that don't match real history either, then you could have endless iterations of alternate histories within alternate histories that keep getting weirder."In my alternate history, Scotland never develops hovercraft, so Canada's cybernetic horses defeat the Belgium-Madagasgar-New Jersey alliance."
