Championship Unification is the act of combining two or more separate professional wrestling championships into a single title.
In professional wrestling, championships may be unified to consolidate the number of championships in a given promotion, or to add legitimacy and prestige to a certain title's lineage. In a title-for-title match, one of four things will happen:
- The lesser championship will be dropped.
- A brand new championship will be created (very rare, but All Japan Pro Wrestling's Triple Crown Heavyweight and World Tag Team titles are prominent examples).
- Both championships retain their identity and may be defended and lost individually (Rob Van Dam holding the WWE Championship and ECW World Heavyweight Championship is a good example of this).
- Both championships will be remain active and be defended and lost together under one name, but title changes will reflect each individual title's history (WWE's Unified Tag Team Championship is a good example of this).
