King Keua Nah (fig.), ruler of Chiang Mai from 1355 to 1385. He reigned in a time of relative and long-lasting peace, of which he knew to make productive use. He brought on the Golden Age of Lan Na in 1367 and introduced the Sinhalese Langka Wong Order in Buddhism, which was considered a purer and a more egalitarian form than the previously introduced varieties from Haripunchai, Pegu and Ava.
