The future Arakanese (ရခိုင်) Rakhine king was born to Princess Pyinsala Sanda (ပဥ္စလစန္ဒာ) and Prince Razagyi in Khamaungseit (ခမောင်းဆိပ်), which is the modern day Maungdaw Township, in the year 1577.
During a war between Taungoo and Arakan, the crown prince Khamaung was captured by the Portuguese mercenary Filipe de Brito e Nicote, and was held for ransom in exchange for his independence from the various Burmese kingdoms until 1603.
[3] Razagyi had formed an unwilling alliance with the Portuguese mercenary captain Sebastian Gonzales Tibao to fend off the Mughals.
[5] The subahdar (governor) of Bengal, Qasim Khan, found this release humane but unstatesmanlike as it missed an opportunity to subjugate Arakan.
[5][6] After the successful defence, Min Khamaung strengthened his military situation by capturing Sandwip back from Tibao with the help of Portuguese mercenaries in late 1617.
