who is the longest reigning undisputed champ?

[ElBossHogg™]

was thinking about this since I posted in the other thread asking who was the last undisputed champ which was jermain taylor and was thinking who the longest reigning undisputed champ was. Who was it in recent times and all time?

Hopkins also had a 10yr reign at middleweight

That was what I was thinking too. Its way harder now that there are a billion ABC belts.
