Mingyi Swa Saw Ke (Burmese: ???????? ?????????, pronounced [m?´?d?à swà s?` k?´]; also spelled ????????, Minkyiswasawke or Swasawke; 1330–1400) was king of Ava from 1367 to 1400.
He reestablished central authority in Upper Myanmar (Burma) for the first time since the fall of the Pagan Empire in the 1280s.
He essentially founded the Ava Kingdom that would dominate Upper Burma for the next two centuries.
When he was elected by the ministers to succeed King Thado Minbya, Swa took over a small kingdom barely three years old, and one that still faced several external and internal threats.
In the north, he successfully fought off the Maw raids into Upper Burma, a longstanding problem since the waning days of Sagaing and Pinya kingdoms.
He maintained friendly relations with Lan Na in the east, and Arakan in the west, placing his nominees on the Arakense throne between 1373 and 1385.
In the south, he brought semi-independent kingdoms of Toungoo (Taungoo) and Prome (Pyay) firmly into Ava's orbit.
But his attempts to extend control farther south touched off the Forty Years' War (1385–1424) between Ava and Pegu.
After three defeats, Swa had to agree to a truce with King Razadarit of Pegu in 1391.
For the most part, his long reign was peaceful.
In contrast to the short reigns by various kings since the fall of Pagan, Swa's 32-year reign brought much needed stability to Upper Burma.
He redeveloped the economy of the kingdom by repairing the irrigation system, and reclaiming much of the arable land which had lapsed into wilderness for nearly a century as the result of the Mongol invasions and repeated Maw raids.
Under Swa's leadership, Upper Burma centered in Ava, finally achieved stability it had lacked for much of the past hundred years.
