According to tradition in very distant antiquity there was a predecessor state in the area named '''''' (ကမ္ဗောဇရဋ္ဌ). The city of Yawnghwe, which gave name to the state, 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. The state of Yawnghwe formally accepted the status of
British protectorate in 1887.
Sao Shwe Thaik was the first president of the
Union of Burma and the last Saopha of Yawnghwe. He married
Sao Nang Hearn Kham of the royal family of
North Hsenwi. His residence in Yawnghwe town, the Haw, is now the
Nyaungshwe Cultural Museum and is open to the public. ==Saophas==
