Other people make Tom Marvolo Riddle their leader and he starts calling himself Lord Voldemort. Over the years, Voldemort makes magical objects called Horcruxes and puts part of his soul in each one. This keeps him from dying all the way and makes it possible for his friends to bring him back to life.
