1. Dāthāsiva.-A thera held in high esteem by Aggabodhi I (Cv.xlii.22). Geiger (Cv.Trs.i.67, n.8) thinks he probably held some sort of position in the king's court, corresponding to that of a purohita.
2. Dāthāsiva.-Minister of Jetthatissa III. He was captured by the forces of Aggabodhi III. at Māyetti, but later regained his freedom and was sent by Jetthatissa to India to cut off Aggabodhi's rearward communications. When Jetthatissa committed suicide and Aggabodhi was once more king, Dāthāsiva returned to Ceylon, defeated Aggabodhi and became king as Dāthopatissa. But his reign was insecure and he was constantly having to flee. He was very rapacious and plundered the temples. Later, to make amends, he built the Sākavatthu-vihāra and restored the Thūpārāma. In the end he fled to India from Kassapa II., but returned later and fought a battle in which he was killed (Cv.xliv.128ff). He had a nephew, Hatthadātha (Cv.xliv.155), who became known as Bhāgineyya-Dāthopatissa. The prince Bodhi and the princess Lokitā were descendants of Dāthopatissa (Cv.lvii.40).
3. Dāthāsiva. A thera, resident of Nāgasālā; he was very learned and held in great esteem by Aggabodhi IV (Cv.xlvi.6).

5. Dāthāsiva.-An ādipāda, ruler of Rohana. His son was Mahinda, who quarrelled with him and, with the king's help, drove him to India and took possession of Rohana. Cv.xlix.10.
