Why does power in some Persian Gulf monarchies rest with an extended ruling family?

In Persian Gulf monarchies, political power rests with an extended ruling family rather than a single individual because these regimes have successfully grafted themselves onto existing tribal frameworks. In this system, the monarch serves as the head of the ruling family, which functions as an extended entity with thousands of members.1

This structure is often described as primus inter pares ("first among equals"), where the ruling family acts as the "first among equals" among the various tribes of the country. Stability is maintained through a process of building political alliances, distributing largesse, addressing grievances, and managing dissenting opinions. Because membership in an extended family or tribe grants individuals a voice in ongoing events, the system maintains a degree of social currency.12

The ruling family retains its position by enforcing a conservative political atmosphere while simultaneously acting as effective state-builders. Furthermore, the family collectively holds the authority to ensure the regime's continuity; for example, they may depose a monarch if his incompetence or inattention threatens the family's standing at the head of society.12
