In combat sports where champions are determined by challenge, the lineal championship in a weight class represents an intangible world title first held by the victor of a bout between top contenders in the division.
"[2][3] There is no universally recognized protocol for establishing the start of each championship lineage, leading to the absence of a single canonical list of lineal champions.
Additionally, when a sanctioning body such as the WBA, WBC, IBF, or WBO strips a title, this action is generally disregarded in determining the lineal champion.
The concept of a lineal champion was developed by boxing fans dissatisfied by the tendency of each of the various sanctioning bodies (WBC, WBA, IBF, WBO, etc.)
Many boxing experts view the lineal championship as a prestigious status which trumps the world titles being issued by the sanctioning bodies (e.g. Steve Farhood).
The exception at this time is Francis Ngannou, who is signed with the Professional Fighters League (PFL) following payment disputes with the UFC.

As he had not fought the highest-ranked opponents in the interim, Cliff Rold conceded, "while the concept of a champion needing to lose a title in the ring is solid, the practice is sometimes highly flawed".
[9] In mixed martial arts, most controversy centers on the proper method for determining the first lineal MMA champion within each weight class.
Others argue that Royce Gracie's victory at UFC 1 in 1993 is the true heavyweight starting point due to the Open-weight nature of the tournament.
