Muhammad Shah of Brunei

Awang Alak Betatar, who as Sultan Muhammad Shah (died c. 1402) founded the Sultanate of Brunei, was, in Brunei tradition, a son of Dewa Emas Kayangan. Ruling first as raja from Kota Batu with his brothers, he cast off Majapahit overlordship and campaigned against the Melanau lands.

In 1363 or 1368 he converted to Islam and took the name Muhammad Shah, becoming Brunei's first sultan, and in 1371 he received a Ming embassy from the Hongwu Emperor. He died around 1402.
