Why did Voldemort make so many horcruxes?

Voldemort wanted to have his soul splited in 7 parts because he believed that 7 was the most powerful number, the number of perfection. Therefore he created intentionally 6 horcruxes in order to have 7 fragments of his soul: the main one – he himself, plus the other parts – the horcruxes.

Why are the horcruxes important?

Horcruxes are powerful objects in which Dark wizards and witches hide fragments of their soul for the purposes of achieving immortality. A Horcrux anchors your soul to earth so even if your body is destroyed a piece of you stays alive. The more Horcruxes you have, the closer you are to immortality.

Why could Voldemort not get another Horcrux?

Voldemort could not get another Horcrux because he did not know he had seven in the first place. When he tried to kill Harry, the spell rebounded and killed him instead. His soul became disembodied and jumped into the closest living thing in the room, Harry.

What is the connection between Voldemort and Harry Potter?

Harry Potter was the accidental Horcrux that Voldemort never intended to make. When his murder attempt failed, a part of his already broken soul took refuge inside of Harry, causing a connection between them that Harry desperately didn’t want.

Is Harry Potter a Horcrux?

Although considered by many as a Horcrux, Harry Potter wasn’t exactly one as a piece of Voldemort was kept inside him by accident: when Voldemort tried to kill Harry and the spell backfired, his soul “broke apart” and a fragment sought out the only other living thing in the room, attaching to it.

Did Voldemort create more than one soul at a time?

So it seems unlikely that Voldemort would create more than that, he was relying on that number providing additional magical support. To clarify, he made six* because he thought (and attempted to confirm with Slughorn) that seven pieces of soul would make the concept of immortality through Horcruxes even more powerful.
