If you could witness any historical event, which one would you choose and why?
reddit.comWhat if Aaron Burr becomes president in 1800 instead of Thomas Jefferson?
The elections in that year still did not distinguish votes in the electoral college for president and for vice-president. And in the first vote they were tied.
What if Burr manages the majority in the first vote and becomes president, with Jefferson as vice-president?
What If WWII never happened, what would the world look like today?
Fascinating thought experiment: What if World War II never happened? No space race, slower tech development, and European empires potentially lasting decades longer. What do you think would be the biggest difference in our daily lives today? Drop your theories below! 👇
What if d-day went better? Got this from chatGPT (air strikes on machine guns, etc) and how it would’ve changed society

What happens in the 1964 election, if JFK is alive to serve two terms?
Hello everyone, I've always been a fan of this era, wanted to ask: Since Nelson Rockefeller was an early frontrunner and began campaigning for the 1964 election in early 1963 while JFK was alive who do you think would actually be the nominee if JFK is alive?..... Rockefeller also suffered that disastrous divorce situation while JFK was alive too so who knows how it would have played down....
So my question again is, Who would have realistically been the Republican Presidential and Vice Presidential nomination in 1964, if JFK is alive to serve two terms?
I'm leaning towards a Goldwater/Ford ticket, I think that's giving a realistic and strategic move for the Conservative Party. Maybe with Goldwater needing to influence the rich midwesterners as best as he could..He would definitely sweep the south like he did irl. I still think JFK gets 486 electoral votes and wins the 1964 Presidential election: & we still get Vietnam (but not as bad), Civil Rights, NASA accomplishments, etc
& just to end with this Who do you think runs in 1968 subsequently due to this fact?
I'm hypothetically leaning Ford/Rockefeller get the win against Humphrey/Muskie, because LBJ doesn't want to run anymore because of his age and health, having spent 8 years as JFK's vice president was enough for him.
Why does the U.S. recognize July 4, 1776 instead of September 3, 1783 when the Brits recognized the U.S. as a sovereign nation?
Why don't we celebrate Treaty of Paris Day?
What if the German and Italian governments jointly bought New Zealand from the British Empire in 1980?
Say that, in 1980, the Italian and German governments had discovered that between them, there were more than $3,000,000,000 worth of Nazi gold hidden in the Swiss Alps. Upon this discovery, they then briefly argue over the gold before realizing that this gold—if monetized—could be put to better use. Realizing that fewer people know of New Zealand than of Australia or Canada or Jamaica or even Bermuda.
Long story short, both nations impulsively decide to buy the whole of New Zealand from the British crown! There were just two small, yet easily solvable problems to this plan: Firstly, the British were even less fond of anything to do with the Nazis than, say, the French! How could this problem be more easily solved, you might be asking? Simple: melt the gold and reforge it into bricks
The second problem? Say that the British government, British corporations, or even the Queen herself had agreed to this proposal; what was in it for any of them? Perhaps in this alternate universe, the British government had spent far too much money on its various wars at the time, from Spanish-speaking Guerilla fighters in Patagonia(both a separate landmass from South America post animal and human migration as well as a jointed Anglo-Spanish colony) Dutch-speaking Guerilla fighters in Australia(a jointed Anglo-Dutch colony in this universe), for instance.
Because these two overlapping problems seemed to both fall into the jointed laps of Italy and Germany, let’s just say that the British Empire of this universe might as well have just given it for free to the rebellious slaves—or migrant workers to use the caste system’s own vernacular—to begin with.
But that’s just my take on it. What are some of your thoughts on this matter?

What individuals can you remove from history and actually prevent major discoveries or events?
I heard someone say recently that if Christopher Columbus had never been born, some other European explorer would've landed on the New World more-or-less around the same time. Events would play out differently, but there's not really a circumstance where no one lands in the Americas around 1500.
It made me wonder who could you pluck out from the timeline and actually prevent major events. For example, if Gavrilo Princip had never been born and thus Archduke Franz Ferdinand wasn't assassinated, does World War I still happen, only with a different match lighting the fuse?
Does the Roman Republican turn into an empire without Caesar? Can the US win independence with a different general leading the continental army?
Are there scientists so singular in their genius that, without them, their discoveries could never have been made by someone else?
What about artists? Does film become a popular medium without the Lumière brothers?
I'm sure there are big, obvious ones I'm not thinking of.
What if at the outbreak of war in 1939, the Imperial Japanese Navy was on a world cruise and was in port in Kiel, Germany?
Japan still maintains a small skeleton fleet of ships in Southeast Asia, enough to run their empire and hold their territories. But the bulk is in Germany. So they can't conduct any meaningful offensive operations in the Pacific like Pearl Harbor.
Let's also say that returning all the way to Japan during wartime would be impossible to due hostile ports and Royal Navy activity.
So the Japanese navy's only meaningful option is to assist Nazi Germany, in the hope of eventually being able to return home by subduing Britain. They carry blueprints with them so that German ports and industries could manufacture spare parts and ammunition for the Japanese ships.
How would this play out? Would Operation Sea Lion succeed if Germany + Japan could rely on Japanese aircraft carriers for air superiority and troop transport?
It's September 1939. WWII has just begun, and, unbelievably, Adolf Hitler gets swallowed up by a time traveling portal while brushing his teeth in the Berghof, warping him to today. He has 1 hour on Google before getting warped back. Can he learn enough to win the war? What should he study?
reddit.comIrradiated Messiah?
I am the only one I’ve ever met to suggest that the Ark of the Covenant in the Bible and in Judaism was filled with radioactive, meteoric slabs. I wonder if this is why Moses’ face shone when coming down from the mountain, why the Ark killed people from opposing camps (they did not respect it and handle it properly), why the guy who was not careful when carrying it died instantly (did the lid slip, exposing him to huge amounts of radiation?), and why High Priests that supposedly were evil or not pure (maybe they opened or sat on The Mercy Seat?) needed to be dragged out? Maybe radiation can explain the red cord of the sacrificial lamb turning white on the SpDay of Atonement? Maybe why Jesus, also a high priest (THE High Priest, actually) could heal others and why other priests could heal others? Maybe this is why Jesus Christ brought others to life, just like how He did, and why the Shroud of Turin seems like it was exposed to radiation bursts. Lemme know your thoughts! And if you ever see a post from someone on YT about it, it’s definitely me. No one has ever talked about this before.
How would world events have played out over the past 100 years if the United States didn’t exist?
No country has had a bigger impact on world events over the past 100 years than the United States. What would the world look like today if the United States didn’t exist to impact events over the past 100 years?
What Would WW2 Have Looked Like of America Didn't Exist?
Considering that the Nazi took a lot of ques from America and then America's role in the war itself, what would Nazi Germany have been like and how would the war have possibly progressed if America didn't exist?
This idea came to me at work, but I'm not a historian. Thank you in advance :)
How could Mexico have become a republic after independence rather than an empire?
I’m writing an alternate timeline where Latin America is stronger and Mexico becomes a global superpower. Is there any way that an independent Mexico would begin as a republic rather than a monarchy? Also, is there any way that Augustin de Iturbide would have agreed to be president rather than emperor, or would someone else (such as Guadelupe Victoria) step in as Mexico’s inaugural president?
If Mexico won the Mexican-American War, would the American Civil War have occurred?
I’m writing an alternate history timeline where Latin American nations form a European Union-esque alliance following a successful Congress of Panama in 1826, leading to a much stronger South America, Gran Colombia not collapsing, and Mexico becoming a superpower. In this timeline, Mexico wins the Mexican-American War, but I was wondering if the American Civil War would have occurred if Mexico was still large. I planned for this timeline to feature the Confederate States winning the civil war and remaining oppressive until a successful revolution during WWI. Would the American Civil War and the Confederate States have existed if Mexico was still large.
What if Hezbollah, and not Al-Qaeda, was responsible for 9/11?
On September 11, 2001, the United States is attacked, very much as it is in OTL.
However, there is an ensuing radio-silence from Al-Qaeda. Bin Laden does not take responsibility for the attacks. Instead, the US government investigation into the hijackings reveals that the terrorists were a cabal of Lebanese Shi'ites—who had in the past received funds and training from Lebanon's Hezbollah.
Hezbollah leadership is dead-silent, and is quietly mortified about the ensuing American retaliation, but the paper trail and the money trail uncovered by American authorities leads to nowhere but them. A little-recognized cabal within the organization ran awry of the leadership's list of approved targets, and targeted American soil, in an ATL-first for Hezbollah.
What happens next? How do the US, Lebanon, Iran, Syria, Israel, Iraq, and Saudi Arabia react? Does NATO immediately launch an invasion of Lebanon (much as it immediately triggered Article 5 and launched an invasion of Afghanistan, in OTL)? Does the US later launch an invasion of Iran, which is Hezbollah's primary source of weapons and funds? Are Afghanistan and Iraq spared from invasion in this timeline?
What if the Spartans had discovered the New World?
Around 350 BC, following the Battle of Leuctra, Sparta was a declining power. Greek colonies were common practice. But what if one expedition went catastrophically off course...I n a desperate move to rescue a declining kingdom, an expedition is sent out to found a colony, as Greek poleis did those days. But what if something went wrong? What if a storm blew them in the wrong direction? What if, against all odds, they survived the journey and found themselves on the coast of Brazil instead?
what if the white population in the South had been 7 million during the American Civil War? Could that have changed the course of the war?
Two scenarios regarding the population reaching 7 million:
1- After the US-Mexico War, there is a massive influx of immigrants from Prussia or other German territories to Texas, resulting in a total of 1.5 million extra German immigrants by 1860.
2- There are higher than normal white birth rates in the southern states, thus increasing the population to 7 million.
