Political administration

The 7th century Telaga Batu inscription, discovered in Sabokingking, Palembang, testifies to the complexity and stratified titles of the Srivijayan state officials. These titles are mentioned: rājaputra (princes, lit: sons of king), kumārāmātya (ministers), bhūpati (regional rulers), senāpati (generals), nāyaka (local community leaders), pratyaya (nobles), hāji pratyaya (lesser kings), dandanayaka (judges), tuhā an vatak (workers inspectors), vuruh (workers), addhyāksi nījavarna (lower supervisors), vāsīkarana (blacksmiths/weapon makers), cātabhata (soldiers), adhikarana (officials), kāyastha (store workers), sthāpaka (artisans), puhāvam (ship captains), vaniyāga (traders), marsī hāji (king's servants), hulun hāji (king's slaves).

During its formation, the empire was organised in three main zones — the estuarine capital region centred on Palembang, the Musi River basin which served as hinterland and source of valuable goods, and rival estuarine areas capable of forming rival power centres. These rival estuarine areas, through raids and conquests, were held under Srivijayan power, such as the Batanghari estuarine (Malayu in Jambi). Several strategic ports also included places like Bangka Island (Kota Kapur), ports and kingdoms in Java (highly possible Tarumanagara and Kalingga), Kedah and Chaiya in Malay peninsula, and Lamuri and Pannai in northern Sumatra. There are also reports mentioning the Java-Srivijayan raids on Southern Cambodia (Mekong estuarine) and ports of Champa.

After its expansion to the neighbouring states, the Srivijayan empire was formed as a collection of several Kadatuans (local principalities), which swore allegiance to the central ruling powerful Kadatuan ruled by the Srivijayan Maharaja. The political relations and system relating to its realms is described as a mandala model, typical of that of classical Southeast Asian Hindu-Buddhist kingdoms. It could be described as federation of kingdoms or vassalised polity under a centre of domination, namely the central Kadatuan Srivijaya. The polity was defined by its centre rather than its boundaries and it could be composed of numerous other tributary polities without undergoing further administrative integration.

The relations between the central kadatuan and its member (subscribers) kadatuans were dynamic. As such, the status would shift over generations. Minor trading ports throughout the region were controlled by local vassal rulers in place on behalf of the king. They also presided over harvesting resources from their respective regions for export. A portion of their revenue was required to be paid to the king. They were not allowed to infringe upon international trade relations, but the temptation of keeping more money to themselves eventually led foreign traders and local rulers to conduct illicit trading relations of their own. Other sources claim that the Champa invasion had weakened the central government significantly, forcing vassals to keep the international trade revenue for themselves.

In addition to coercive methods through raids and conquests and being bound by pasumpahan (oath of allegiance), the royalties of each kadatuan often formed alliances through dynastic marriages. For example, a previously suzerained kadatuan over time might rise in prestige and power, so that eventually its ruler could lay claim to be the maharaja of the central kadatuan. The relationship between Srivijayan in Sumatra (descendants of Dapunta Hyang Sri Jayanasa) and Sailendras in Java exemplified this political dynamic.
