WFTDA

The Women's Flat Track Derby Association, commonly known as WFTDA, is an international governing body for women's flat track roller derby. It was founded in 2004 to standardize rules and promote the sport of roller derby. WFTDA sets the official rules of roller derby, which are used by its member leagues worldwide. The organization also organizes tournaments and championships, including the annual WFTDA Championships.

Membership in WFTDA is open to any women's flat track roller derby league that adheres to its rules and standards. Member leagues are responsible for their own governance and operations, but they must comply with WFTDA regulations to participate in sanctioned events. WFTDA is committed to promoting inclusivity and diversity within roller derby, and it has adopted policies to ensure a welcoming environment for all participants.

The sport of roller derby itself is a full-contact team sport played on roller skates. Two teams of five skaters each compete on a flat track. The objective is to score points by having designated players, known as jammers, pass opposing players. WFTDA has played a significant role in the resurgence and professionalization of roller derby, transforming it from a niche sport into a globally recognized athletic competition.
