Quidditch, the sport inspired by J.K. Rowling s Harry Potter books, has changed its name to quadball.

Today marks a monumental step in the history of our sport, and it marks an equally big step for Major League Quadball, the league said in a news release Tuesday.

Two of the sports governing bodies, U.S. Quidditch and Major League Quidditch, announced last year they were pursuing a name change for two reasons.

First, because the name quidditch was is trademarked by Warner Bros., it limited the sports expansion and its sponsorship and broadcast opportunities.

Second, the leagues hoped a name change could help them continue to distance themselves from the works of J.K. Rowling, who has come under scrutiny for anti-trans remarks in recent years.

Our sport has developed a reputation as one of the most progressive sports in the world on gender equality and inclusivity, in part thanks to its gender maximum rule , which stipulates that a team may not have more than four players of the same gender on the field at a time, they said at the time. Both organizations feel it is imperative to live up to this reputation in all aspects of their operations, and believe this move is a step in that direction.

The International Quidditch Association will also adopt the name change globally.
