How did Harry survive against Voldemort as a baby?

Lily Potter sacrificed her life in order to protect her infant son, Harry from Lord Voldemort. This placed Harry under magical protection, so that when Voldemort cast the Killing Curse at Harry in turn, the spell backfired, leaving him unharmed (save for a lightning-shaped scar on his forehead) and Voldemort bodiless.

What if Harry Potter had parents?

If Harry’s parents had lived, he would still be Harry, but he probably would be subtly different. Living in the hostile environment of the Dursley home, Harry develops some traits that might be less evident if he had grown up in happier circumstances. For instance, he develops an unusual degree of self-reliance.

Why was Voldemort willing to let Lily live?

He wanted to hurt Harry, and knew exquisite detail would do so. It was intentional: Voldemort wanted Harry to know that he gave Lily the chance to live. He wants to understand that because of him (Harry), Lily made the conscience decision to die, rather than hand her son over to death.

Why didn’t Harry Potter die at Voldemort’s hands?

Harry’s encounter with the Killing Curse in the Forbidden Forest has resulted in a lot of confusion, but there are essentially two main reasons in Harry Potter canon that explain why he didn’t die at Voldemort’s hands as an adult.

Could Dumbledore have defeated Voldemort if he survived?

Had Dumbledore survived, for at least one more year, then Lord Voldemort could have been defeated quicker. The Hogwarts headmaster was wise and chances are that he knew what the Dark Lord’s Horcruxes were before Harry did.

Why doesn’t the prophecy about Voldemort ever come true?

As it was, though, he attacked Harry, and for that reason, everything else the prophecy predicts comes true; HOWEVER, none of it actually happens because the prophecy itself predicts it. Harry is not bound by the prophecy to face Voldemort.

How many times did Voldemort ask Lily to step aside?

Voldemort asked Lily three times to step aside but Lily didn’t. Lily chose to sacrifice herself to save Harry, that’s a sacrifice – a life for a life – therefore, when Voldemort still went after Harry after having killed Lily, that’s the moment where the curse rebounded.
