This is a list of world champions who have been certified by The Ring magazine. The Ring is a boxing magazine that was founded in 1922. In 2002, The Ring created a championship system that is "intended to reward fighters who, by satisfying rigid criteria, can justify a claim as the true and only world champion in a given weight class".[1] There are currently only two ways that a boxer can win The Ring's title: defeat the reigning champion; or winning a box-off between The Ring's number-one and number-two rated contenders (or, sometimes, number-one and number-three rated).[2] There are also only three ways that a boxer can lose The Ring's title: lose a championship fight, move to a different weight class, or retire.[2] (The Ring does not strip its champions' titles like the sanctioning bodies do.)
