In 1935, during the Great Depression, Leo Seltzer invented a spectacle called Roller Derby.

Sometime in early 1935, Leo read an article in Literary Digest magazine that said ninety-three percent of Americans roller skated at one time or another during their lives. Discussing the article with some of the regulars at Ricketts, a restaurant in Chicago’s Near North Side, Seltzer was challenged to come up with a sport utilizing roller skating participants.

Originally, the derby was a long distance track race. Periodically, collisions and crashes occurred as skaters tried to lap those ahead of them. Seltzer realized this was the most exciting part of the event, and Roller Derby became a full-contact sport with elbowing, body checks and fights. The fans loved it. The sport peaked in the late forties and fifties, drawing as many as 30-40 thousand fans per bout. The hype continued through the sixties and seventies, until the expense of travel and competition from other entertainment forms killed off the larger leagues in the late 1970s.

Since then, Roller Derby has remained largely dormant until recently. The National all-female derby revival began in 2001 in Austin, Texas, and has been gathering speed ever since. The new generation of derby skaters pays homage to the theatrical tradition of the past, but play by real rules with real penalties, real referees and real champions. Modern day roller derby is a fast-paced, hard-hitting, explosive sport that combines the spirit of Seltzer’s vision with genuine athleticism.

Derby Myths and Facts:

Fact: Roller Derby is a true sport, and as such, all the hits, plays and penalties you see play out on the track are real and not staged.

Myth: You can tell the hits and fights are fake because they don’t get hurt.

Fact: All skaters are required to wear protective padding and train to fall in order to minimize injuries to themselves and others. But injuries can and do happen. EMT and other trained medical personnel are present at all bouts to ensure skaters receive immediate medical attention in the case of an injury.

Roller Derby Scoring and Gameplay:

Roller derby is certainly not like football or baseball in that there is no ball put into play. Instead, it more closely resembles a race, in that one skater — called a jammer — must get through a pack of skaters and pass all of their opponents. If the jammer cannot get past their opponents, no points are scored by their team. There are three positions — jammer, blocker and pivot — who attempt to block their opponents in order for their teammate to get through. Roller derby skaters find themselves simultaneously playing offense and defense as they skate around the track.

Roller Derby Pack

Two teams of five players each are on the starting line. The jammers for each team are in the back, and take off at the same time as the pack of blockers, signaled by one sharp whistle. The goal is for the jammer to lap everyone on the oval track and begin scoring points. For every opponent a jammer passes, they score a point. All the while, the other four players, called blockers, are trying to block or knock down their opponents to make it harder for the opposing jammer and easier for their own jammer to score.

The Pivot

At the starting line, the blocker with the striped helmet is the pivot. This position guides the speed of the other blockers, paying attention to where both teams’ jammer are. The pivot might signal for their team to skate faster, so it is harder for the other team’s jammer to catch up to the pack and thus score before the clock runs out. The pivot might signal for their team to slow down if they sees that their own jammer is trying to catch up to the pack.
