The known history of the Lanna-related dynasties and rulers begins with the founding of the Ngoenyang Kingdom, inaugurated by Lawachangkarat in 638.[1] This was succeeded by the Lanna Kingdom and then as a tributary state of Siam in 1775 until it was annexed to Thailand in 1909,[2] and the title of the ruler of Lanna Chiang Mai was dissolved in 1939.[3]
