ウィジャヤ
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.
