Bayin Htwe was a son of
Thado Minsaw who proclaimed independence of his minor kingdom from
Ava in 1482. Htwe ascended the throne in 1526 after his father's death. His formal title was
Thiri Thudhamma Yaza (သီရိသုဓမ္မရာဇာ). The new king soon incurred the wrath of
Saw Lon, the leader of
Confederation of Shan States because he did not send help in the Confederation's war against Ava in 1526–1527. His father had been an ally of Lon, and sent troops in their 1524–1525 assault on Ava. In 1532, Lon and his Confederation armies (12,000 troops, 800 horses and 30 elephants) laid siege to Prome. Htwe surrendered in late 1532, and was sent to
Dabayin in Upper Burma in exile. Htwe's son
Narapati was appointed vassal king. Htwe's life in captivity was cut short after Lon was assassinated by his own ministers near
Myedu, enabling his return to Prome. He arrived back at the outskirts of Prome, five months after he lost his throne. But Narapati did not allow him back in the city. He died about a month later in the adjoining forests. ==Family==
