Just a reminder before we start: fan theories are supposed to be fun speculations meant to open up the mind to a different angle of thinking. We are in no way insinuating that any of this is stone cold fact.
Now, is it just me, or is it just a casual happenstance that Gellert Grindelwald's defeat in 1945 coincides with WWII ending in September of that same year?
According to user NugatRevolution's theory posted on Reddit, he or she thinks not. NugatRevolution believes that WWII as a cover-up by the wizarding community to hide muggles from what was really a magical war.
Think about it for a second. The dates do parallel nicely. And Grindelwald did want to take over the muggles, as he saw wizards and witches as much more superior.
Isn't it also strange that Grindelwald ended up in a prison called Nurmengard (an homage to Nuremberg, the famous city in Nazi Germany that was at the forefront of rallying and anti-Semitic laws)?
Too many things just seem to add up here. Perhaps there is a slight connection. Which must mean that Albus Dumbledore, who was once friends with Grindelwald, not only defeated him in 1945; he also saved the entire world by ending WWII.
Just when we thought Dumbledore was already a badass, he proves to us that he is so much more.
