Ba Saw Nyo (Burmese: ဘစောညို, in Burmese pronounced as /ba̰ sɔ́ ɲò/; also known as Muhammad Shah; 1435–1494) was king of Arakan from 1492 to 1494. He came to power in 1492 after his nephew King Dawlya had died after a failed military expedition. He made Dawlya's mother and his sister-in-law Saw Nandi his chief queen.[2] He faced a serious mutiny by an officer, which was put down. He died later in case of assassination by a rebellious soldier named Nga-Swe.[3]
