The name given to the northern part of Ceylon, with Pulatthipura as centre, as opposed to Rohana (E.g., Cv.lxx.184f ) and Dakkhinadesa (Cv.lxxii.176-9). Later, the name was changed to Patitthárattha (E.g., Cv.lxxxii.26).
Rájarattha was the scene of many conflicts between the Singhalese and the invaders who came from time to time from South India, till, in the end, it was abandoned, and the Singhalese capital moved southwards. Rájarattha was also called Rájinorattha. E.g., Cv.lii.4.
