Minye Kyawswa II of Ava  Minye Kyawswa (, ; also spelled Minyekyawswa; 16 November 1567 – late December 1599) was heir apparent of Burma from 1593 to 1599, and viceroy of Ava from 1587 to 1593. For the last six years of his life, he was the deputy of his father King Nanda, who presided over the collapse of the Toungoo Empire. In December 1599, he betrayed his father, and defected to the forces led by Minye Thihathu II of Toungoo and Raza II of Arakan. But the promise of good treatment was not kept; the last crown prince of the Toungoo Empire was killed a few days later. The prince was born to Crown Prince Nanda and his chief consort Hanthawaddy Mibaya 16 November 1567 in Pegu (Bago). He was the sixth child and the second son of the couple, and had six other full siblings. The prince grew up in Pegu during the reign of his grandfather King Bayinnaung, who had founded the largest empire in Southeast Asia. After Bayinnaung died on 10 October 1581, his father Nanda succeeded without incident. Minye Kyawswa became second in line of succession behind his elder brother Mingyi Swa, the heir-apparent. However, the days of the empire were numbered. The new king did not have the support of his major vassals, who ruled what used to be sovereign kingdoms just a few decades earlier. By 1584, Nanda faced serious rebellions in Ava (Upper Burma) and Siam. The king relied on Mingyi Swa to keep the empire intact. Minye Kyawswa was not a factor. Unlike other senior princes of the day, he did not take part in any of the early military campaigns—Chinese Shan States (1582–83), Ava (1584), and Siam (1584, 1586). The prince's first major assignment came in September/October 1586. Governor Min Letya of Ava, whom Nanda appointed just two years earlier, had just died in office. The king appointed his second son by his chief queen viceroy of Ava with the title of Minye Kyawswa, effective —the date deemed propitious by the court astrologers. To help the young prince govern Upper Burma, the king also sent along a dozen senior seasoned officials led by Baya Yawda (as chief minister), and Let-Yway-Gyi Myin Hmu (as commander of the military).
