Son of Kassapa V, and brother of Sena II and Saṅghā. When the Ādipāda Kittaggabodhi raised a rebellion in Rohaṇa against Udaya II, the latter sent Mahinda to quell it with the help of the general Vajiragga. The expedition was completely successful and Kittaggabodhi taken prisoner. Mahinda stayed in Mahāgāma and ruled over Rohaṇa justly and well. Among his works was the construction of a dam across the Mahānadī (Cv.li.99 ff). When Kassapa IV became king, Mahinda revolted against him, but the king, through the influence of Mahinda’s father, persuaded him to desist. Later, Mahinda returned to Anurādhapura at the request of the monks, and, after having married the king’s daughter, went back to Rohaṇa, where, evidently, he died. Cv.lii.4 ff.
