How did oil revenues increase the power of Arabian Peninsula governments after the 1960s?

Following the 1960s, oil revenues fundamentally transformed the Arabian Peninsula, enabling governments to consolidate power and expand their influence through a "rentier state" framework. By deriving national income from the export of petroleum rather than domestic taxation, ruling elites became the primary allocators of resources, which reinforced their authority and ensured regime durability.12

This wealth allowed governments to extend their reach from coastal areas into the interior and solidify control through several key mechanisms:

• Distributive Systems: Governments utilized oil income to fund expansive welfare systems, infrastructure development, and large public sectors, effectively supplementing traditional pillars of power—religion and dynasty—with economic benefits for the populace.12
• Modernization and Infrastructure: Revenues financed rapid urban transformation, including the construction of major metropolitan hubs, international airports, and state-of-the-art educational and cultural institutions.2
• Military and Regional Cooperation: In response to regional tensions, such as the Iran-Iraq War, states used their wealth to expand military capabilities and formed the Gulf Cooperation Council in 1981 to coordinate defensive and economic efforts.13

Ultimately, this fiscal structure allowed ruling families to remain at the core of political and economic life, integrating their states into global energy markets.2
