Rajamandala refers to a geopolitical theory originating from Indonesia rather than a specific city or geographical location. It describes a traditional model of foreign policy and spatial organization based on the concept of concentric circles of influence.
The theory postulates that political relationships are defined by proximity to a central ruler's state, known as the raja. According to this framework, a neighboring state or a neighbor of a natural friend is considered a natural enemy, while a neighbor of a natural enemy is regarded as a natural friend. This results in alternating circles of allies and enemies radiating outward from the center.
