“Unlocking Secrets: Mind-Bending Harry Potter Theories That Redefine the Wizarding World’s Legacy!”

The Defense Against the Dark Arts classroom wasn’t cursed by just anyone. It was cursed by Dumbledore. That’s what one theorist believes. Even though Dumbledore knew Snape was the most qualified professor to teach the students, he refused to let him fall under the curse.
The reason Dumbledore cursed the classroom was to make sure no one would hold the position for longer than a year at a time. He finally gives in to Snape after he makes an unbreakable vow to kill Voldemort. The theory, unfortunately, does not fully explain why it’s important to have a new teacher every year.
