A Horcrux is an object in which a Dark wizard or witch has hidden a fragment of his or her soul for the purpose of attaining immortality.
The first Horcrux was created by Herpo the Foul long before the modern era. The only other known creator of a Horcrux was Lord Voldemort, who was possibly the only person to have successfully created more than one Horcrux.
The nature and concepts of Horcruxes were so terrible, they were kept secret from most of the wizarding world, and very few people were ever made aware of their nature. Hogwarts banned any study of the subject of Horcruxes.
The only known book that provided specific instruction on the creation and nature of a Horcrux was Secrets of the Darkest Art, which was once held in Hogwarts' library. Due to the book's extremely dark and dangerous nature, Albus Dumbledore hid it away in his office when he became the Headmaster of Hogwarts. It was believed that Tom Riddle had found the information necessary to make a Horcrux in this book before Dumbledore managed to get ahold of it. While a Horcrux could be anything at all, including a living being, it was most advisable to create a Horcrux out of an inanimate object to decrease the chances of it being destroyed.
Horcruxes by their nature appeared to be extraordinarily durable, as only very destructive magics and processes could truly destroy them.
To create a Horcrux, a wizard first had to deliberately commit murder. This act, said to be one of supreme evil, would result in the murderer metaphysically damaging their own soul. A wizard who wished to create a Horcrux would then use that damage to their advantage by casting a spell which would rip the damaged portion of the soul off of the whole and encase it in an object. Apparently the wizard would have to perform an unspeakable act as part of the ritual. If the maker was later killed, he or she would continue to exist in a non-corporeal form, although there were methods of regaining a physical body. However, according to Horace Slughorn, few would want to live in such a form and death would be preferable to most.
As a fragment of soul, a Horcrux seemed to retain the identity of its creator at the time of its creation. Voldemort, for instance, created a Horcrux during what was presumably his fifth year at Hogwarts. As such, the fragment of soul contained within the Horcrux took on the appearance and mannerisms of Voldemort as he had been when he was 16 years old.
Horcruxes were said to be essentially the opposite of a person. Where a person's container, their body, could be destroyed without any damage to their soul, the fragment of soul contained inside a Horcrux was dependent on the container for it's existence. If the container was destroyed, so to would be the fragment of soul within it.
Horcruxes were originally conceived of as being a singular act. As such, it was unknown for many centuries what the attempted creation of multiple Horcruxes would result in, as nobody thought it possible to accomplish such an act. However, the wizard Voldemort managed to create seven Horcruxes in the hope that it would make him stronger than just creating one.
It was stated at one point that Voldemort had already "pushed his soul to the limit" in creating his seven Horcruxes. This implied a finite number of Horcruxes any one person may create before the process became too dangerous to attempt again. It also implied that the creation of a Horcrux used a set amount of soul, and that this amount was the same every time the process was undertaken. Though this limit was never explicitly stated, the number seemed to hover around seven intentional Horcruxes. Creating seven Horcruxes in addition to the fragment of soul in a person's own body rendered the soul unstable and liable to break apart if the creator of the Horcruxes was killed. For instance, Dumbledore explicitly stated that Voldemort's soul had become so unstable that it simply "broke apart" when Voldemort tried to murder Harry Potter for the first time on October 31, 1981 in Godric's Hollow
