The document discusses the world of Harry Potter created by J.K. Rowling. It explains that Rowling's premise is that magic folk like wizards and witches live secretly alongside Muggles in the present-day world. It suggests that over 1,000 years ago, four founders established Hogwarts School of Witchcraft and Wizardry and the Ministry of Magic was formed to organize the Wizarding world and contain magical creatures from Muggles. Harry Potter's world encompasses both the ordinary Muggle landscape and the magical landscape where witchcraft is normal.
