Explanation:

Sukaphaa also Siu-Ka-Pha, the first Ahom king in medieval Assam, was the founder of the Ahom kingdom and the architect of Assam. A Tai prince originally from present Mong Mao, Yunnan Province, China, the kingdom he established in 1228 existed for nearly six hundred years and in the process unified the various indigenous ethnic groups of the region that left a deep impact on the region. In reverence to his position in Assam's history the honorific Chaolung is generally associated with his name (Chao: lord; Lung: great). Since 1996 December 2 has been celebrated in Assam as the Sukaphaa Divox, or Axom Divox (Assam Day), to commemorate the advent of the first king of the Ahom kingdom in Assam after his journey over the Patkai Hills.
