​J.K. Rowling ended her Harry Potter series in 2007, then the movies ended the Wizarding World  (after the second Wizarding War) in 2011. 

But then... came Fantastic Beasts and Where to Find Them- which turned into a multi-film series- and after that, came Harry Potter and the Cursed Child, a follow up play and story that takes place nineteen years after the original books.

The door to the Wizarding World is always open, and no, I'm not talking about just to the theme parks. There's always something that allows you to step into the world of Harry Potter even if it's for a little while from the books, to the movies, and even to the play if you can see it.

However, what makes the world of wizards and witches so popular to many? One theory is (just like with Star Wars), Harry Potter reinvents and reworks the "mythic pattern" Joseph Campbell describes in The Hero With a Thousand Faces, where the hero goes from the ordinary world into a supernatural one, battles with magical forces, and then returns with these gifts to help others.

Another theory has to do with J. K. Rowling's background in which she studied French literature at the University of Exeter, thus why many elements of medieval French romances such as themes, characters, and plot structures are interspersed throughout the books.

Scholars Heather Arden and Kathryn Lorenz, authors of The Harry Potter Stories and French Arthurian Romance, point out many facets of the series that are a reference to or even parallel Arthurian lore and that familiarity with the story makes it potent for many. For instance, many Hogwarts professors are members of the medieval "Order of Merlin," and many creatures have been taken out of a medieval romance such as unicorns, dragons, basilisks, werewolves, and the phoenix.

Harry himself is even likened to Arthur in that he gains a magical weapon (in this case his wand) that aids in his battles against dark forces. Harry, like Arthur, is accompanied by loyal companions who aid him and who battle alongside him- but at times, even he must part from them to face a challenge alone. And in another, on the nose likeness, Harry pulls a sword from an object and fated to marry a girl named Ginevra (which is actually a derivation of Guinevere).

Whatever the reason behind Harry Potter's fame, all Potterheads can agree that these books are classics!
