most historic weight division?

[Bori Bori]

Top 3 IMO
1.Heavyweights
2.Welterweights
3.Fetherweights

[The Gambler1981]

I think it generally goes
Welterweight
Lightweight
Middleweight

Although with the cesspit middle has really been for 2 decades I could see moving up feather to number 3. Light heavy would probably be in the mix also.

Are we talking historically famous or historically great?

[Tony Trick-Pony]

You have to go with heavyweight. It isn't the best all the time, but the heavyweight crown is the biggest prize historically.

[NChristo]

The deepest are Lightweight or Welterweight, Light Heavy or Middle 3rd.

[Pigeons]

Anybody that doesn't go with Heavyweight is trolling.

James J. Jeffries
Jack Johnson
Jack Dempsey
Gene Tunney
Joe Louis
Rocky Marciano
Floyd Patterson
Sonny Liston
Muhammad Ali
Joe Frazier
George Foreman
Larry Holmes
Mike Tyson
Evander Holyfield
Lennox Lewis
Vitali Klitschko
Wladimir Klitschko
Deontay Wilder

Are we talking historically famous or historically great?

Yea, the question made no sense. If it's memorable, then HW all day. Ali, Frasier, Foreman, Tyson, Holyfield are all household names, so to speak, not to mention numerous other names that people recognise, even if they don't follow the sport.

[LomaUsykKlichko]

Has to be Heavyweight

[SlySlickSmooth]

The most memorable is probably Heavyweights.

Historically great? Probably Welterweight, Lightweight, then Light Heavyweight/Middleweight

[Sugar Adam Ali]

1 heavyweight
2 welter
3 middleweight
