Wiang Prueksa
Wiang Prueksa (also spelled Wiang Pueksa; Thai: เวียงปรึกษา), also known as Wiang Chiang Saen Noi (เวียงเชียงแสนน้อย), was an ancient polity of the Tai Yuan people, centered at Ban Sop Kham (บ้านสบคำ), in present-day Chiang Saen District, Chiang Rai Province, Thailand. It comprised a number of settlements that survived the fall of the Yonok Kingdom, traditionally attributed to earthquakes in the late 5th century. In the mid 7th century, the Tai Yuan people of Wiang Prueksa invited Lao Chakkaraj, a leader of the Lawa people from Doi Tung, to become their new ruler. After ascending the throne, Lao Chakkaraj constructed a new city at Mae Sai and established it as his principal center under the name Hiran Nakhon, marking the beginning of the Ngoenyang Kingdom. This polity later developed into the Lan Na Kingdom, which was formally established in 1292 during the reign of King Mangrai the Great.
