1. No Haber-Bosch

    OTL WWI Germany relied heavily on the Haber-Bosch process for high explosives. What if the process hadn't been invented yet? What is going to happen to the German war effort? 1. Assuming it doesn't get developed at all, how does WWI go? 2. Alternatively, what happens if Germany does a crash...
  2. AHC: Post WWI Habsburg Germany

    With any POD after the beginning of WWI, put the Habsburgs on the throne of Germany.
  3. WI: Karl of Austria without WWI

    Suppose Karl of Austria somehow comes to the Austro-Hungarian throne without WWI. Perhaps both Emperor-King Franz Joseph and Archduke Franz Ferdinand die earlier in the 1910s or they die on schedule but alt-WWI is pushed back a few years. How would Karl's rule look without a world war going on...

    Soviet Russia after an early end to WW1?

    Could Lenin or other Communists rise to power in Russia if Germany surrendered late 1917 or early 1918 instead of November 11, 1918? Assuming Lenin still ends up in Russia somehow.

    US postwar politics if Roosevelt won in 1912

    How would the Democrat and Republican parties be different if president Taft decided to not seek reelection for whatever reason and ex-president Theodore Roosevelt went on to win the Republican nomination and the 1912 election? Particularly how it would affect the Republican party in 1920...

    WI: Battle of Sarikamish was an Ottoman victory.

    The plan for battle of Sarikamish devised by Enver Pasha while great on paper was too complex by half for the troops to enact. But what if Battle Sarikamish was an Ottoman victory. How would the this effect the Ottoman Empire and the Russian empire. Would it cause an earlier Russian withdrawal...
  7. WI: Alberto Pollio survives

    In 1914, during the leadup to World War I, Italian general Alberto Pollio died. The official cause of death was a heart attack, but suspicions that he was murdered have floated for over a century. What if he had lived?

    Alternate Aircraft of Nations

    This is inspired by the long running alternate warships of nations thread and works fairly similar to that long running discussion. You can post your scenarios and alternate aircraft here, as well as post any basic questions regarding plausibility of certain scenarios, viability of aircraft...
  9. Franz Ferdinand became emperor of Austria-Hungary in 1909?

    It shouldn't be too difficult to imagine the aging emperor Franz Joseph I dying around seven years earlier than OTL. He was a very old man by then, already in his late seventies, so it shouldn't be too difficult for him to catch a cold that turns into pneumonia and kills him. This means that...
  10. Masters of Fate : Alternate WWI TL

    Peace The masses ran out onto the streets on the evening of the 7th of August 1919. News of peace talks came with mixed reactions. Many couldn't wait to meet their couragous sons, proud fathers, loving husbands or caring brothers, some hadn't heard from their loved ones since the infamous...

    Archduchess Elisabeth Marie Marries Future King Albert I

    So I recently discovered that Archduchess Elisabeth Marie sought, and nearly married, future king Albert I of Belgium. Leopold II disapproved due to the recent morganatic marriage of his daughter Stephanie. Say Stephanie does not marry again, forever scarred by the venereal disease that Rudolf...

    DBWI : Germany holds on to Lorrain ores

    The Great War was a bloody, but relatively short affair, only two years. The Central Powers were riddled with shortages, which they hoped to alleviate via conquest. One of the most critical ones was the German iron ore shortage. Not only did Germany already import French iron ore from the...

    AHC: Russian Republic signs a separate peace.

    After the February revolution, the Provisional government, including figures like Lvov, Milyukov, and Kerensky kept Russia loyal to its diplomatic commitment to the Entente, which would result in the eventual destruction of the Republic. Why did the ruling government ignored the mass desertions...

    A History of Alyska to the year 1800.

    Thanks to Covid I have had a lot of free time, and have spent it getting back into writing. Among the various projects I have been working on has been an alternate history setting, the timeline of which will appear here.

    AHC: Ruin the World Economy Post-WWI

    My challenge to you is with a POD after the fall of France, make the war so terrible that the World economy is ruined for everyone.

    PC: An East Prussian - Lithuanian Union?

    What if in the aftermath of WWI, the Entente had merged East Prussia with Lithuania as part of the Treaty of Versailles? The Lithuanians would receive a larger population, the Poles would be less likely to try revanchist schemes (or would they?) and the Soviets would see the new nation as less...
  17. What would a present day without World War 1 look like?

    Essentially no Fascism, no Communism, no Art Deco, no Prohibition, no "Dieselpunk". How do you think a world like this would evolve like in the 20th and 21st centuries? People becoming increasingly sexually open and naturalistic, with an Art Nouveau style spreading its comfortable vines all...

    Ivan Kolev Survives

    This video from The Great War is a great introduction to this man, if you don't know of him. And his Wikipedia page: https://en.wikipedia.org/wiki/Ivan_Kolev_(general) He died on 29 of July 1915, in Vienna while being treated for tuberculosis (according to the Great War; Wikipedia just said...
  19. Place In the Sun: What If Italy Joined the Central Powers?
    Threadmarks: Introduction

    Hello, everyone. So, I've lurked here for quite some while before registering recently, and I've decided to start a timeline based on a question which has always fascinated me: what if Italy joined the Central Powers in 1915? This timeline's PoD is that Germany forces Austria to agree to terms...
  20. WI: The scale of Serbia's involvement in the Black Hand is revealed just after the assassination of Franz Ferdinand?

    Let's say that the intelligence division of Austria-Hungary, and specifically their investigations into the Black Hand, is significantly better than OTL. They are able to capture enough Black Hand agents or otherwise investigate the organization thoroughly enough that shortly after Franz...
