King of Sri Lanka, Udaya IV. (A.C. 945-953). He was a friend of Sena III (perhaps his younger brother, see Ep. Zey.ii.59) and was his yuvarāja. On Sena’s death, Udaya succeeded him and reigned for eight years. During his reign the Coḷā invaded Sri Lanka, but were repulsed (Cv.liii.28, 39 ff; also Cv.Trs.i.177, n.2). Among his religious activities was the erection of the Manipāsāda, which, however, he could not complete. Cv.liv.48.
