History
Although the junior middleweight class was one of the junior weight divisions created in New York by the passage of the Walker Law in 1920, there were no claimants to the title until 1963, when suddenly two fighters claimed the title: Ernile Griffith and Dennis Moyer.
Griffith became a middleweight soon after winning recognition as the European champion, so the championship lineage generally begins with Moyer.
The lists below include generally recognized champions, as well as champions of the National Boxing Association/World Boxing Association (NBA/WBA), World Boxing Council (WBC) and International Boxing Federation (IBF).
Some other champions recognized by New York (NY), Great Britain (GBR), Europe and the European Boxing Union (EBU) are also included, if they seemed to be genuine claimants and /or later won recognition from an international body.
Only those bouts are included in which the championship changed hands or the championships of two or more governing bodies was unified.
