The Harry Potter series was made infinitely more interesting and dark with the introduction of the Horcruxes. These were the pieces of soul that Voldemort had imparted from himself to ensure he remained immortal and the final two books were all about vanquishing these Horcruxes. All in all, the wizarding world has more information and Easter eggs to offer about the Horcruxes than just the ones regarding Voldemort, as there's an extensive history behind their creation.
J.K. Rowling has also revealed deeper information about Voldemort's Horcruxes since the series has come to an end and it's worth checking all of these out to see just how dark the Harry Potter series can get.

Herpo the Foul was an ancient Greek wizard who can be seen as the pioneer for the dark arts. He was the first man to breed a basilisk, was a known Parselmouth, and is implied to have been Salazar Slytherin's ancestor.
It was Herpo the Foul who also uncovered secrets of the human soul, becoming the first wizard to create a Horcrux by splitting his soul. The killing was committed through his basilisk that he order to take a life. This places the earliest known use of a Horcrux back over a thousand years from the events of the Harry Potter series.22822Magical detail?

Harry learned about Voldemort's creation of Horcruxes based on the memory of Professor Slughorn where Voldemort asked the teacher if he could split his soul. However, the truth is that he had already created a Horcrux by the point. This was through the death of Myrtle Warren, whom he'd killed by using the basilisk. He created the diary Horcrux through Myrtle's death, making it the first Horcrux he had created.17714Magical detail?

Creating a Horcrux was easier said than done, as there were many wizards who did try to do just that, only to meet their own demise. The process of splitting a soul is supposed to be physically traumatizing, to the point where it can very well be fatal.
"Wizards would've been looking for ways to do exactly what Voldemort did for years, and some of the ways they would've tried would've killed them. Something that people imagined might be able to be done, but couldn't quite bring it off, and then...people started doing it with sometimes catastrophic effects."16110Magical detail?

Despite Herpo the Foul having created a Horcrux a millennia ago, he was the only known person to have split his soul until Voldemort did the same. This places Voldemort and Herpo the Foul as the only two wizards to have ever created Horcruxes, further proving how even extremely dark wizards avoided creating Horcruxes while Voldemort truly did push the boundaries by splitting his soul so many ways.17118Magical detail?
