co-ruler
Joint sovereign partner
A co-ruler is someone who shares ruling authority with another, governing jointly rather than alone.
The term appears in historical contexts where two monarchs, emperors, or leaders held power simultaneously: The aging king appointed his son as co-ruler.
The relationship may be equal or hierarchical, with one co-ruler holding more actual power than the other.
