The chronicle of this region, titled the Mong Mao Chronicle, was written much later. Some scholars identify Mong Mao with the Kingdom of Pong, as well as with the kingdom of Luh Shwan mentioned in Chinese chronicles. Like most of Tai Yai history, the history of the Kingdom of Pong is largely legendary and existing chronicles and traditions include conflicting names and dates which have led to different interpretations. Mong Mao arose in the power vacuum left after the Kingdom of Dali in Yunnan fell to the Mongol Yuan Dynasty around 1254. The Yuan ruled the region indirectly in what was known as the Native Chieftain System. This kingdom had asserted some unity over the diversity of ethnic groups residing along the southwest frontier of Yunnan. In 1448, a combination of Ming, Sipsongpanna, and other allied forces subjugated Mong Mao. "Mong Mao" is sometimes used by authors to refer to the entire group of Tai states along the Chinese-Myanmar frontier including Luchuan-Pingmian, Mong Yang/Mong Yawng??, and Hsenwi, even though specific place names are almost always used in Ming and Burmesesources. The center of power shifted frequently between these smaller states or chieftainships. Sometimes they were unified under one strong leader, sometimes they were not. As the Shan scholar Sai Kam Mong observes: "Sometimes one of these strove to be the leading kingdom and sometimes all of them were unified into one single kingdom ... The capital of the kingdom shifted from place to place, but most of them were located near the Nam Mao river " The various versions of the Mong Mao Chronicle provide the lineage of Mong Mao rulers. The Shan chronicle tradition, recorded very early by Elias, provides a long list with the first ruler of Mong Mao dating from 568 A.D. The dates in Elias for later rulers of Mong Mao do not match very well the dates in Ming dynasty sources such as Ming Shilu and Baiyi Zhuan which are considered more reliable from the time of the ruler Si Kefa. Kazhangjia, translated into Thai by Witthayasakphan and Zhao Hongyun, also provides a fairly detailed local chronicle of Mong Mao.
Chaolung Sukaphaa was the founder of the Ahom kingdom in what is now parts of Assam. A Tai prince originally from Mong Mao, founded the kingdom in what is now Charaideo region of Assam, in 1228 and existed for nearly six hundred years which led to the process of Ahomisation and in the process unified the various indigenous ethnic groups of the region under the banner of 'Ahom' that left a deep impact on the region. In reverence to his position in Assam's history the honorificChaolung is generally associated with his name. Since 1996 December 2 has been celebrated in Assam as the Sukaphaa Divawkh, or Axom Divawkh, to commemorate the advent of the first king of the Ahom kingdom in Assam after his journey over the Patkai Hills.
