Yawnghwe (Burmese: Nyaung Shwe) was a Shan state in what is today Burma. It was one of the most important of the Southern Shan States. Yawnghwe state included the Inle Lake. The administrative capital was Taunggyi, located in the northern part of the state. The Agent of the British government, the Superintendent of the Southern Shan States, resided at Taunggyi and the king's palace was at Yawnghwe.
According to tradition in very distant antiquity there was a predecessor state in the area named Kambosarattha. The city of Yawnghwe, which gave name to the sate, was founded in 1359 by two mythical brothers, Nga Taung and Nga Naung, who arrived from Tavoy (Dawei) and were allowed to build a capital by a prince who ruled the region. The brothers brought 36 families from Tavoy and established themselves in the new city. Yawnghwe included the subsidiary states of Mawnang (Heho), Mawson, Loimaw, Loi-ai and Namhkai. Historically the majority of the population in the state belonged to the Intha, Pa-O, Danu, Shan and Taungyo people groups.
Formerly the Saopha of Yawnghwe would personally welcome the four Buddha images during the annual festival at Hpaung Daw U Pagoda, an 18-day pagoda festival, during which the Buddha images were placed on a replica of a royal barge designed as a hintha bird and taken in a procession throughout Inle Lake. The elaborately decorated barge was towed by several boats of leg-rowers rowing in unison together with other accompanying boats. The images would be taken from the royal barge and a grand procession would take them to the palace or haw of the Saopha, entering the prayer hall from the eastern entrance, where the images would be kept for a few hours.
Nowadays the festival is still held, but the images bypass the visit to the haw and are taken directly to the temple.
