    Why Didn’t Grindelwald Recruit Tom Riddle? - Harry Potter Theory

    22/06/2026 | 22 mins.
    A while back I made a video called ‘Why Didn't Voldemort Try to RECRUIT Grindelwald?’, and basically- the focus of that video was why Voldemort never made any attempts to recruit an imprisoned Grindelwald at Nurmengard. On both occasions that Voldemort rose to power, Grindelwald was sitting in a locked tower, so it always felt a bit peculiar to me that he wouldn’t have tried to recruit the most powerful resource at his disposal..Especially at times when things weren’t looking particularly good for him.

    But in today’s video, I want to explore a different timeline that I FEEL has entirely different dynamics, one in which Grindelwald, at the height of his power, recruited a young Tom Riddle. I think this arrangement is far more likely, far more plausible and far more dangerous.

    I’d also like to put forth a bold statement: the version of Voldemort that we got in the existing timeline Is NOT the most dangerous version.

    Topics Covered In This Video:

    What if Grindelwald recruited Voldemort?

    Why didn’t Grindelwald recruit Tom Riddle?

    Why didn’t Grindelwald and Voldemort team up?

    Tom Riddle’s Horcruxes in an alternate timeline

    What if Voldemort never disappeared after Hogwarts?

    Could the Death Eaters have formed under Grindelwald?

    What if Grindelwald was never defeated in 1945?

    Dumbledore vs Grindelwald alternate timeline explained

    How Voldemort could have inherited Grindelwald’s movement

    The First Wizarding War alternate timeline explained

    Harry Potter alternate history and what if theories

    Wizarding World lore analysis, theories, and explanations

    Questions Answered:

    Could Grindelwald and Voldemort have worked together?

    Could Grindelwald have recruited Tom Riddle from Hogwarts?

    Was Tom Riddle alive during Grindelwald’s war?

    Would young Voldemort have followed Grindelwald?

    Would Grindelwald have trusted Tom Riddle?

    Would Tom Riddle have betrayed Grindelwald?

    Did Grindelwald and Voldemort believe the same things?

    What is the difference between Grindelwald and Voldemort?

    Could Grindelwald have made Voldemort more dangerous?

    Was the canon version of Voldemort the most dangerous version?

    Would Voldemort still create Horcruxes if he joined Grindelwald?

    Would the Death Eaters still exist if Voldemort joined Grindelwald?

    Would Dumbledore still defeat Grindelwald in 1945?

    Could Tom Riddle have stopped Dumbledore from defeating Grindelwald?

    What if Grindelwald stayed in power after 1945?

    Could Voldemort have taken over Grindelwald’s empire?

    How would the First Wizarding War change?

    Is this the darkest Harry Potter alternate timeline?
