Rajarata [rā dja ra tə] (Meaning: King's country) (Sinhala: රජරට) (Tamil: ரஜரட) was one of three historical regions of the island of Sri Lanka for about 1,700 years from the 6th century BCE to the early 13th century CE. 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, Malayarata 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.
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.
Administrative centres in Rajarata:
Prince Vijaya and his clan settled in Tambapanni, near the Malvatu Oya delta. According to Mahavamsa, various groups came from India in the period between Prince Vijaya and King Pandukabhaya's reign, frequently settling along the Malvathu Oya. In 377 BCE, King Pandukabhaya moved the administrative centre to Anuradhapura. Most of the settlements were located near rivers and reservoirs. Water was used for agricultural purposes. According to the Yodha wewa area in Mannar District by King Dhatusena, Eropathana in Vavuniya District, Padawiya area in Anuradhapura District and Mullaitivu District by King Moggallana II the extent of Sri Lanka's golden civilization spread to the southern boundary of the Vanni forest. The thick Vanni forest acted as a barrier to colonizers above the southern border of the forest. Tanks built during the Anuradhapura era (Giant's, Padaviya, Minneriya, Kantale, Mahavillachchiya, Thabbowa, Kala) are proof of the early settlements in Rajarata area.
Initial settlements based near rivers:
Boundaries of the three divisions (Rata):
In 1215, Kalinga Magha invaded Rajarata with an army of 24,000 soldiers. After the conquest of Rajarata, Magha established his capital in Pollonnaruwa. Then the Kalinga forces extended their power to the Malaya Rata. During the rise of the Kingdom of Dambadeniya under the king Vijayabahu III (1220-1224 CE), Magha lost the control of Malaya Rata. The native Sinhalese resisted the Magha's administration at Pollonnaruwa. The Sinhalese gathered around inaccessible towns, fortresses and mountains including Yapahuwa and Gangadoni under army generals including Subha and Sankha. Because of the rising threat, Pandyan troops established an administration centre in Jaffna Peninsula which was more secure and isolated by the impenetrable Vanni forest. Later Rajarata was annexed by king Parakramabahu II(1236–70). His power extended over Rohana, the central hills, Rajarata and the Vanni.
The Sinhalese tried to re-establish the administrative centre in Rajarata but this never happened because of constant battles with invaders from south India. The administration centre was moved away from Rajarata by the Sinhalese. The defeat of Pandyan in South India in the rising Mogul empires weakened the Tamil power in Sri Lanka. The last Pandyan ruler of Madurai, was defeated and expelled in 1323 by Malik Kafur, the army general of the Muslim empire Delhi Sultanate. The falling of Pandyan was a historical event that had a big impact for Sri Lanka.
It leads to following events:
Also, ancient Rajarata (before the 13th century) was divided into three parts:
