Launggyet
The Launggyet dynasty ruled the last Arakanese kingdom of the Le-Mro period, seated at Launggyet in the Kaladan valley from 1251 until its fall to Ava in 1406. It grew rich as a trade link between Bengal and Southeast Asia.
Its greatest king, Min Hti, took the throne as a child around 1279 after the usurper who had murdered his father was killed. Arakanese chronicles credit him with a reign of nearly a century. His armies repelled Shan raids, and he crossed the Arakan Mountains to sack Thayet and founded Ann in 1335.
Min Hti died around 1374 without a legitimate heir. His great-grandson Narameikhla took power in 1404 but was driven into exile in Bengal when Ava seized Launggyet in 1406. Returning with Bengali troops in 1430, he founded Mrauk-U, where Min Hti's line continued.
