Start of rebellions '', was drowned for his failed assassination attempt of his uncle Shwenankyawshin Like his predecessors before him, the new king at Ava had to reestablish his authority over the vassal states. At first, the long-term rebellion by his uncle
Minye Kyawswa of Yamethin ended with the latter's death in June/July 1501 (Waso 863 ME, 16 June to 15 July 1501). But rebellions resumed almost immediately. In November/December 1501 (Natdaw 863 ME, 11 November to 9 December 1501),
Nawrahta of Yamethin, the eldest son of Thihathura II, sent an assassin to kill Shwenankyawshin, which nearly succeeded. Both the assassin and Nawrahta were caught. Nawrahta, of being royal blood, was drowned. A desperate Narapati tried to keep
Toungoo (Taungoo) as an ally by giving the all-important
Kyaukse granary to the nominally vassal kingdom but
Mingyi Nyo of Toungoo declared independence in October 1510, and gave no help. Ava's only steadfast ally was
Hsipaw (Thibaw) led by its
saopha Hkonmaing I of Onbaung–Hsipaw. Troubles continued. Sawlon seized
Bhamo, Hsipaw's vassal in 1511, and raided deep into Upper Burma in 1517–1518. In 1519, the Shan state of Kale also revolted, and Ava had to reclaim it. By the early 1520s, Avan territory had shrunk so much that it was not much bigger than its former vassal states. In late 1523, the Confederation and Prome jointly attacked Ava's territories from the north and the south. Ava with Hsipaw fought back but gradually got squeezed in. A year and half later, on 22 March 1525, the combined armies sacked Ava, forcing Narapati and Hkonmaing to flee the city. In 1527, the Confederation forces again came back and laid siege to Ava. On 14 March 1527, the king died from a gunshot wound while fighting in the battle. The Confederation took Ava, and their leader
Sawlon made his son
Thohanbwa king of Ava, making it just another Shan state. The conquest ended Ava's 163-year (1364–1527) role as the dominant power in
Upper Burma (Myanmar). Many people from Ava fled to Toungoo, the only remaining safe haven. ==Namesake==
