The queen dowager Atula Thiri was shocked by her son's decision not to punish his son for stabbing his grandfather, and instigated Toungoo to revolt. Toungoo, a remote province in the southeastern part of Ava Kingdom, had a long history of insurrections. Its last rebellion lasted seven years (1451–1458). Toungoo called in help from
Hanthawaddy Pegu. Thihathura dispatched an army under Gen.
Sithu Kyawhtin, who was accompanied by two of his sons. The governor of Toungoo resisted with the help of Pegu but was defeated in 1470. The princes spared the rebellious governor's life, and carried him off to Ava, leaving Sithu Kyawhtin as the head of the troublesome province. Next, the king sent an army to gain submission of Prome, and pardoned his brother
Mingyi Swa who was lord there. In 1475 the king with help from the Shan State of
Hsipaw (Thibaw) raided
Yawnghwe (Nyaungshwe), securing its submission. In early 1476 (837 ME), he sent an expedition against Hanthawaddy, and raided Kawlia near Hlaing. In 1476, Sithu Kyawhtin, lord of Toungoo, enlarged his town. The ministers perceived that this meant Toungoo was about to revolt but the king showed them they were wrong by telling him to let himself be dragged by the hair to court; he did so, saying "It is my king’s command". Thihathura sent envoys to
Ceylon in 1474. The envoys brought a broom made of the hair of the king and queen, and its handle studded with gems to sweep the floor of the
Temple of the Tooth at
Kandy. ==Death==
