1. Sena. King of Ceylon (Sena I., 831-51 A.C.). He was the younger brother and the successor of Aggabodhi IX. He had three younger brothers: Mahinda, Kassapa and Udaya. His queen was Sanghā. During his reign the Pandu king invaded Ceylon, and Sena had to retire into the Malaya district. After the army of the Pandu king had plundered a great part of the kingdom, Sena made a treaty with him and re-gained his throne. He adopted the three sons and the three daughters of Kittaggabodhi: Kassapa, Sena and Udaya, and Sanghā, Tissā and Kitti. Among the king's good acts was the construction of a monastery on Aritthapabbata for the Pamsukulikas, and a many storeyed pāsāda in Jetavana. He also built the Vīrankurārāma, the Pubbārāma, Sangha-sena-parivena, Senaggabodhi-vihāra, a refectory in the Mahāmettapabbata-vihāra, and single cells in the Kappūra and Uttarālha-parivenas. He completed the Dappulapabbata- and the Kassaparājaka-vihāras. Among Sena's ministers were Bhadda (the senāpati), Uttara, Vajira and Rakkhasa. His capital was in Pulatthinagara (Cv.l.1ff). He was also known as Silāmegha (Cv.l.43).
2. Sena. Son of the Adipāda Kassapa, and therefore nephew of Sena I. On the death of his father, Sena became king as Sena II. (851-85 A.C.). He married Sanghā, daughter of Kittaggabodhi, and had a son, Kassapa. Sena sent an expeditionary force against the Pandu king, captured Madhurā, and brought back the treasures which had been pillaged by the Pandus in the time of Sena I. The Pamsukulika monks separated from the incumbents of Abhayagiri in the twentieth year of Sena's reign. He built the Manimekhala dam and a dam across the Kanavāpi at Katthantanagara. He endowed various monasteries - Buddhagāma, Mahiyangana, Kūtatissa, Mandalagiri, and Sobbha - and held a special ceremony in honour of the image of Ananda. He held a consecration festival at the Hemavāluka-cetiya (Mahā Thūpa), and decreed that this festival should be repeated annually. His senāpati was Kutthaka. Cv.li.1ff.

Once, when he was absent, Sena V. had the senāpati's younger brother, Mahāmalla, slain for an offence with the queen mother, and appointed a court official Udaya as senāpati. When Sena senāpati heard of this, he marched against the king, who had to flee to Rohana. The queen mother joined Sena, and he lived in Pulatthipura. This king, later, dismissed Senāpati Udaya and made peace with Sena, whose daughter he married. Cv.liv.13f.; lviii.70.
