#2 Light Heavyweight Championship (1997-2001)
Why did WWE retire the Light Heavyweight Championship?

WWE had several titles that were too similar to each other after Vince McMahon bought WCW in 2001, so it was inevitable that there would be multiple unifications in 2001-2002.
The Light Heavyweight Championship had been a regular presence on WWE programming from 1997 to 2001 but WWE decided to revamp its Light Heavyweight division (aka cruiserweights) by merging the Light Heavyweight Championship with the WCW Cruiserweight Championship.
X-Pac was the final holder of the Light Heavyweight Championship after he suffered an injury in November 2001, causing his scheduled unification match with Tajiri at Survivor Series to be cancelled.
Why will the Light Heavyweight Championship never return?
WWE reintroduced the Cruiserweight Championship in September 2016 after TJP won a 32-man Cruiserweight Classic tournament. Since then, a weekly show – 205 Live – has been created to showcase WWE’s cruiserweights.
Needless to say, with so much weekly television time dedicated to the cruiserweight Superstars on the roster, there is no need for WWE to ever rename its 205 lbs-and-under Superstars “light heavyweights”.
