Dual kingship is a political system where two rulers share power over a single kingdom or territory. This arrangement can help balance authority and prevent conflicts, as each king may represent different factions or regions within the realm. Historically, dual kingship has been seen in various cultures, such as in ancient Egypt, where the pharaohs often ruled alongside a co-regent. This system allowed for a division of responsibilities and could enhance stability by ensuring that both rulers had a vested interest in the kingdom's welfare.
