been awarded a Sima status with portion or the whole of its rice tax revenue was allocated to funding the construction and maintaining the temple. Nevertheless, it is quite possible that the Prambanan Plain with high concentration of temples located just few hundred metres away from each other—Sambisari, Kalasan, Sari, Sewu, Lumbung, Prambanan, Plaosan, Sajiwan, Banyunibo, Ratuboko, Barong and Ijo temples—might be the location of the capital of Mataram. Other experts argued that the Prambanan area was indeed the religious centre of the kingdom, but was not the administrative centre, while suggesting other locations in Muntilan as the possible political centre of the kingdom. Most of the time, the court of the Mataram Kingdom was located in Mataram, possibly located somewhere in Muntilan or the Prambanan Plain near modern Yogyakarta. However, during the reign of Rakai Pikatan, the court was moved to Mamrati. Later, in the reign of Balitung, the court moved again, this time to Poh Pitu. Unlike Mataram, historians have been unable to pinpoint the possible locations of Mamrati and Poh Pitu, although most historians agree that both were located in the Kedu Plain, somewhere around the modern Magelang or Temanggung regencies.

The King was regarded as the paramount ruler or chakravartin, where the highest power and authority lies. He ruled the nagara or kadatwan which means the kingdom, from his puri (palace or walled compound). Under the king, there are state officials that serve to forward the king's laws and orders.
