Saw Yun

Saw Yun (c. 1299–5 February 1327) was the founder of the Sagaing kingdom in Upper Burma. The eldest son of King Thihathu of Myinsaing–Pinya and Queen Yadanabon, he was angered when his father named his adopted stepbrother Uzana I heir, and in 1315 crossed the Irrawaddy to build Sagaing, where he repelled two Pinya expeditions by 1317. He remained nominally loyal to his father while ruling Sagaing in practice.

In 1318 he formed the thousand-strong Sagaing cavalry regiment. After Thihathu's death in 1325 the two kingdoms split, and Saw Yun died in February 1327; his three sons all ruled Sagaing.
