Rajarata (Sinhala: රජරට, romanized: rajaraṭa (IPA:[rad͡ʒəraʈə]); Tamil: ரஜரட, romanized: rajaraṭa; meaning "King's country") 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, 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.
Anuradhapura (Sinhala: අනුරාධපුරය, romanised: Anurādhapuraya, IPA:[ənuraːd̪əpurəjə]; Tamil: அனுராதபுரம், romanised: Aṉurātapuram, IPA:[ɐnuɾaːðɐβuɾɐm]) is a major city located in the north central plain of Sri Lanka. It is the capital city of North Central Province and the capital of Anuradhapura District. The city lies 205 kilometers (127 mi) north of the current capital of Colombo in the North Central Province, on the banks of the historic Malwathu Oya. The city is now a World Heritage Site famous for its well-preserved ruins of the ancient Sinhalese civilisation.
While Mahāvaṃsa places the founding of the city in 437 BCE, the site has been inhabited for much longer, making it a major human settlement on the island for almost three millennia and one of the oldest continuously occupied cities in Asia. It is the cradle of the Hydraulic Sinhalese civilisation, Theravada Buddhism, and the longest-serving ancient capital of Sri Lanka that has survived for 1500 years. Moreover, it was the first capital of the Sinhala Kingdom of Rajarata, following the kingdoms of Tambapanni and Upatissa Nuwara. Anuradhapura was also the centre of Theravada Buddhism for many centuries and has been a major Buddhist pilgrimage site with ruins of many ancient Buddhist temples, including the famous Anuradhapura Maha Viharaya and the Jaya Sri Maha Bodhi, the oldest still-living, documented, planted tree in the world believed to have originated from the original Bodhi tree at Bodh Gaya (Bihar, India) under which the Buddha attained enlightenment. These vast networks of ancient temples and monasteries now cover over 100 square kilometers (40 sq mi) of area of the city today.
