Several ancient cities, including Tambapanni, Upatissa Nuwara, Anuradhapura and Polonnaruwa, were established as capitals within the area by successive rulers. Rajarata was under the direct administration of the King (raja/king, rata/country). Two other areas, Mayarata and Ruhunurata, were ruled by the king's brothers "Mapa" and "Epa" . The Magha invasion in the 13th century brought about the end of the Rajarata kingdom.

== History and kingdoms == The first kingdom in Rajarata was established by Prince Vijaya in 543 BCE. He settled near the delta of the Malvathu River between Chilaw and Mannar. According o a local myth, Prince Vijaya married a local princess, Kuveni, to gain control of Rajarata. With her help, he betrayed and killed all of the regional leaders. After his death, the administrative center was moved to the countryside along the Malvathu Oya. The river was ideal for agriculture. The first three administrative centres Tambapanni, Upatissa Nuwara, and Anuradhapura, were situated close to the Malvathu Oya. King Pandukabhaya, once a prince descended from local Yaksha and Sinha tribes, formed a stable kingdom in Anuradhapura. He garnered support from tribes in different areas of the island.
