    Threadmarks: Introduction

    I'm new on this forum so I'm not fully sure how it works, I have been working on this timeline over the last few years on and off, revamping it entirely several times over, because of this there's probably a hundred different documents and maps that all now have various degrees of canonicity...
  2. The Western Expanse

    A group of other AH fans and I work on an alternate history scenario on Discord and I want to hear your thoughts. It goes as such. Over 100 million years ago, the Farallon Plate subducted at a shallow angle under America. The definite reason why is still a mystery to science. This subduction...

    AH Battles Thread

    Inspired by the AH Quote thread and Cultural Descriptions thread, I decided to make a similar thread to alternate battles. They don't have to be Pre-1900, and they must not have happened OTL at all in the precise space, you are creating the circumstances for an AH battle to take place, describe...

    What about a Napoleonic Kingdom of Germany?

    How plausible would it be? (implausible, moderately plausible, plausible, very plausible) What would the scenario be like? What would be its effects in the short and medium term? And in the long term? Would you like a scenario like that? I await your thoughts 🙂

    DBWI: Less popular Alternate History genre

    Well.. Since I am watching Man in the high castle series on Amazon Prime, it seems that Alternate History genre is getting more popular, recently, we saw Pavane or Bring the Jubilee becoming very popular, earning 9 figure box office, if not billions. I wonder if it wasn't so?

    Oldest AH story on the Internet

    Exactly as the title says, what is the oldest known Alternate History story to appear on the Internet?
  8. Great Lakes Earth

    Let us say that, in the future, some scientists have created satellites capable of something that seems science fiction for now—punching the walls of the universe to study an alternate reality. By that scenario, some hundreds of “alternate Earths” from hundreds of alternate universes would...

Those who had given birth to children were allowed to retire into luxury in a palace. Although secluded, they would want for nothing the rest of their days. Those who had...
  10. the best ways on how to achieve a better-off Chile

    There are a multiple ways in which Chile, which had the similar economic potential early in the 20th century as Australia and New Zealand, could have infinitely become better off than the mess it has become in the past 50-plus years. I find some the best ways are: 1. Avoid the severe...

    The Dragon’s of the East

    This will be a sounding board for ideas on an alternate history timeline that was started almost 4 years ago. I admit that there are several fantastical ideas here, but that’s why I’d like input and assistance in ironing out the details of this timeline. Thank you to all that will participate...

    AHC: Two (Or More) Israels/Jewish States?

    While researching something on the Six Day wars, I stumbled upon an illustration of several proposed Jewish states/possible alternate history Israels, and that led to a rabbit hole of proposed Jewish states throughout history. There were so many variations of the idea of giving the Jews their...
  16. Challenge: Make the Romans reintroduce Gladius, Scutum and Pilum wielding legions after Justinian

    For Byzantine timeline lovers, this one may be interesting. The date is not set and you can choose whatever POD from 532 to 1453 as long as its set on the Byzantine period. The typical roman legionary that lurks in the collective mindset is that of the Gladius wielding, Pilum throwing armored...

However, there will be no science fiction type material such as dimension flipping and alternate universes. This is just a unique crafted...
  18. AHC: The Black Death killed 90% of people in Eurasia

    Another challenge of mine (muahahaha), so what if a particularly virulent and fatal strain of the Black Death evolved in the grasslands of Central Asia prior to its spread across Eurasia, maybe the genome of the bacteria was changed by a few base sequences or so. By the mid 13th century, the...
  19. AHC: With a POD after 1200, repulse the Reconquista and recover Al-Andalus

    Al-Andalus was in decline for centuries (corruption and decadence come into mind) and was at its death kneel by 1200 with the power balance clearly in favour of the Christian Kingdoms of Portugal, Castille and Aragon. However, I challenge you to do whatever you can to not only repel the...
  20. WI: What if Ismail al-Jazari invented the steam engine?

    There are several historical figures that were not too far off inventing the steam engine however, al-Jazari was undoubtedly the closest, in the early 13th century... A proto-industrial revolution with only al-Jazari's inventions is a possibility, he invented an early crankshaft in 1206 [1], he...
