The British and Irish Quidditch League was established in 1674. Due to the need to maintain anti-Muggle security, the professional League was formed of the thirteen best teams at the time, and all others were asked to disband. Amateur teams are still permitted, once they meet departmental requirements. Each year, the teams compete for the League Cup. The teams have also competed for the Josef Wronski Award for Excellent Pitch Skills and individual players for the Dangerous Dai Llewellyn Commemorative Medal. Teams from the league also participate in the European Cup. The league falls under the authority of the Department of Magical Games and Sports.
