I've only ever seen 'you get to kill one person as a baby' alternative history polls, but I think there's a more interesting version so let's play 'change one event in history'! (Go for what you think would do the most good or what would be the most chaotic choice. It's a thought experiment we're not the morals police!)

Very brief (and grossly oversimplified!) explanations under the cut.

unfortunately my education has been very eurocentric and I'm pretty hopeless at the nuances of history pre-19th century; this is as diverse as i could make it (which is not very diverse at all). Please feel free to add in the tags!

1) This assassination set WW1 in motion (triggered/enabled the first declaration of war)

2) Emmanuel de Grouchy was a general in Napoléon's army. Before the Battle of Waterloo he'd been given the order to cut off the Prussian General Blücher, but Blücher had already got to the battlefield so de Grouchy went off on a pointless search with his 40-50k soldiers instead of joining the battle, which many consider a significant reason for Napoléon's defeat.

3) i.e., make trouble after Columbus leaves for America but before he arrives there.

4) Georg Elser attempted to set off a bomb during a Hitler speech at a beer hall. (There were other attempts on Hitler's life both before and after this, I just picked this one). The explosion failed to kill Hitler as he had moved his speech up half an hour and was gone by the time the bomb went off. It killed seven Nazis and a waitress. Elser was arrested, sent to a concentration camp and murdered days before its liberation at the end of the war. This has nothing to do with the question, I just hate that everyone only knows about the Stauffenberg one.

5) This position allowed Stalin to pick functionaries for key positions in the Soviet Union and thus pave his way to becoming Lenin's successor.

6) likely preventing the USA from creating a functional atomic bomb before the end of the war.

7) Günter Schabowski held the famous press conference which communicated the GDR's intention to allow East German citizens to cross into West Germany again without having to apply for government permission. Asked when this would come into effect, Schabowski replied, visibly uncertain, "to my knowledge, that is immediately. Right away". This led to crowds overwhelming the Berlin border crossings. The officers stationed there had received orders to mark the passports of all those crossing with a stamp that would barr them from re-entry into the GDR, but did not uphold this and instead simply opened the barrier as they feared violence would break out. This became the night the Berlin Wall fell.

8) The battle was a huge deal for German propaganda both at the time and later on and made especially Hindenburg a war hero, but I mostly picked it because I figure it'd be easiest to get them both at once during a battle. Both men were central to the decisions the German Empire made in WW1 (to such a degree that people have argued they effectively led the country) and both played a role in Adolf Hitler's rise to power: Ludendorff lent his credibility and fame to Hitler's Munich Beer Hall putsch in 1922, and Hindenburg went on to become the last president of Weimar Germany and appointed Hitler chancellor in 1933.
