Tommy Ryan retired in December 1906. Ryan gave the title to Hugo Kelly, although Kelly was not accepted by the public as the new champion before Kelly lost his claim to Billy Papke. The title was also claimed by Jack Twin Sullivan and Stanley Ketchel. Stanley Ketchel defeated Joe Thomas, Jack Sullivan and Billy Papke to re-establish lineage. (see title fights)

Stanley Ketchel PTS20 Billy Papke

Ketchel was murdered in October 1910. Papke had claimed the title in March 1910, thinking Ketchel had vacated, and he continued his claim after Ketchel’s death before losing to Cyclone Johnny Thompson, who lost to Frank Klaus. Georges Carpentier also claimed the title, before losing to Klaus. Papke re-claimed the title, after being recognised in Britain as world champion. Klaus defeated Papke in 1913 and is generally regarded as lineal champion from this win. Australia, however, recognised Eddie McGoorty after his win over Dave Smith. The lineage of McGoorty’s claim ended with Les Darcy’s death in 1917. (see title fights)
