Harry Potter is a series of fantasy novels written by British author J. K. Rowling.
 The novels chronicle the life of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry.
 The main story arc concerns Harry's struggle against Lord Voldemort, a dark wizard who intends to become immortal, overthrow the wizard governing body known as the Ministry of Magic, and subjugate all wizards and muggles, a reference term that means non-magical people.
Harry James Potter is the title character and protagonist of J. K. Rowling's "Harry Potter" series.
 The majority of the books' plot covers seven years in the life of the orphan Potter, who, on his eleventh birthday, learns he is a wizard.
 Thus, he attends Hogwarts School of Witchcraft and Wizardry to practise magic under the guidance of the kindly headmaster Albus Dumbledore and other school professors.
 Harry also discovers that he is already famous throughout the novel's magical community, and that his fate is tied with that of Lord Voldemort, the internationally feared Dark Wizard and murderer of his parents, Lily and James.
The immense popularity and wide recognition of J. K. Rowling's Harry Potter fantasy series has led to its being extensively parodied, in works spanning nearly every medium.
 The franchise holds the record for the most fan fiction parodies, at over 900.000 Some self-described parodies have been targeted by Rowling and her publishers as plagiarism, while others have sold hundreds of thousands of copies without any threat of legal sanction.
 Misinterpretations of "Harry Potter" parodies have sparked at least two urban legends.
 Many "Harry Potter" parodies are self-published; others are put out as part of major comic productions, such as "Mad", "The Simpsons", "South Park", "Saturday Night Live" and "Robot Chicken", all of which have parodied "Harry Potter" several times.
 Rowling has also been parodied (and parodied herself) in a number of instances.
Death Eaters are fictional characters in the "Harry Potter" series of novels and films.
 They are a group of wizards and witches, led by the dark wizard Lord Voldemort, who seek to purify the Wizarding community by eliminating the Muggle-borns (wizards or witches born to non-magical parents).
 They also try to create a new order through the Ministry of Magic and spread fear throughout the Wizarding community by terrorising and killing important officials and other enemies of the Death Eaters, chiefly the members of the Order of the Phoenix.
 Although the reason why they are called "Death Eaters" has not been explained by J.K. Rowling, there is some evidence to suggest that it is a reference to their ultimate goal of preventing death and achieving immortality.
