First, a run-down of the particulars:
- Due to potential metric conversion issues and weight class changes, a limit of 161 pounds is observed for this list.
- Inception of the championship occurred on 1/13/1990, the first fight between two top fighters that resulted in a clear #1.
- Sporadic periods of inactivity were observed throughout the first half of the lineage. Clear “top contender” matches took place to determine the next champion.
Your current lineal Lightweight champion is Islam Makhachev

Cerrone had the belt lol

Can’t make this shit up.
Will Ilia vs Charles be for the new lineal title?
I would think so. Based on points I believe Ilia would be #2 LW currently.
There is a mistake, Oliveira fought against Chandler for the vacant lightweight title, and then defend it against Poirier and Gaethje
The lineal title is not necessarily the same as the UFC title, though they very often coincide.
Oliveira vs Chandler was not considered eligible for the vacant LW lightweight title, even though it was a UFC title bout. We typically wait until there is a top-ranked contender matchup to fill a vacancy. Oliveira was ranked #3 and Chandler #6 at the time, so we did not consider this bout as the for the lineage. The Poirier fight was #1 vs #2, so that’s where we picked up the lineage.
I think that Poirier vs McGregor 2 was for the lineal championship. Khabib- unofficially retired – said that they were the best lightweight at the moment. Poirier was a former interim champion and after the loss against Khabib he faced and defeated a top 5 (Hooker). Conor was the former UFC undisputed & Lineal Champion and after the loss agaist Khabib he faced and defeated a top 5 (Cerrone), although in a ww bout. Poirer at the moment of victory against Conor was the uncrowned champion.
McGregor was ranked #10 Welterweight at the time of the second Poirier fight, thus was not eligible for the lineage consideration.
