Today we’re learning more about the Quidditch World Cup, the tournament first seen in Goblet of Fire, thanks to a great new article from J.K. Rowling.

Over the past couple weeks, the Harry Potter author encouraged fans on Twitter to retweet a rugby-related hashtag in order to open up new details about the Quidditch World Cup on Pottermore.

Rowling tweeted this morning that she received enough retweets to release the new material.

The historical look at the long-running Quidditch tournament offers information concerning when the Cup began, what the rules are, and discusses four “infamous tournaments” including the one we read about in Goblet of Fire.

For example, Rowling humorously writes about a tournament held in the year 1877 which no witch or wizard can remember. Not one.

“The ICWQC insists that a tournament has been held every four years since 1473. This is a source of pride, proving as it does that nothing – wars, adverse weather conditions or Muggle interference – can stop wizards playing Quidditch,” Rowling writes.

“There is, however, a mystery surrounding the tournament of 1877. The competition was undoubtedly planned: a venue chosen (the Ryn Desert in Kazakhstan), publicity materials produced, tickets sold. In August, however, the wizarding world woke up to the fact that they had no memory whatsoever of the tournament taking place.”

“Neither those in possession of tickets nor any of the players could remember a single game. However, for reasons none of them understood, English Beater Lucas Bargeworthy was missing most of his teeth, Canadian Seeker Angelus Peel’s knees were on backwards and half the Argentinian team were found tied up in the basement of a pub in Cardiff.” Rowling goes on to share theories about how everyone forgot the tournament.

The historical look at the Quidditch World Cup also explains several of the tournament’s many, many rules. “The rulebook concerning both on- and off-pitch magic is alleged to stretch to nineteen volumes and to include such rules as ‘no dragon is to be introduced into the stadium for any purpose including, but not limited to, team mascot, coach or cup warmer’ and ‘modification of any part of the referee’s body, whether or not he or she has requested such modification, will lead to a lifetime ban from the tournament and possibly imprisonment.’”

Part 2 of this look at the Quidditch World Cup will arrive next week. The Pottermore Insider says that it will include recaps of tournaments as recent as 2014. This is the first time we’re getting present day information about the Wizarding World, as far as we can remember.
