>>272083401>I've recently started wondering if the world was effectively mind-wiped 60-70 years ago and if everything we know about "history" is a complete fabrication.
Probably. Not in an /x/ kind of way though, but by selective censorship.
Here in germany, it's still pretty obvious if you read diaries or autobiographies unrelated to "history". Starting around the invention of the high-pressure steam engine (by german Jacob Leupold btw, long before Watt was even born), official history diverges from what happened.
It's most obvious with the anti-german propaganda during ww1, when school books and encyclopedias in UK and US were modified to no longer contain german acheivements. Most notably, the motorized flight of Weisskopf (a german who migrated to the US) was denied in spite of multiple witnesses and newspaper reports, and the Wright brothers were suddenly presented as the first to build a working motorized plane.>What if "ancient history" only took place 100 years ago?
Definitely not. I don't know how it is in the US, but here in europe, it's common for the older families to have their own "chronicles", which list birth and deathdates, as well as notable events (like familymembers obtaining medals, going to war etc.). Unless there was some type of world-spanning conspiracy, you wouldn't be able to fake them all.
And at least the ones I've seen all agree that "modern" technology like firearms or steam engines have been around for centuries already. For example, my family's ancestral home was built in the 1700s, and was already set up for canalisation (a covered ditch) and water main (still made of wood and lead back then) - though the head of the family back then noted that due to us not owning all the land up until the city boundaries, he couldn't actually connect it and still needed to dig a well.
