period According to the Khamyang Chronicle, the Khamyangs first came into Assam in the time of
Sukaphaa, then went back to the
Patkai mountains and founded a settlement near the
Nong Yang Lake, which they derive their name from. In the Ahom chronicles, prince
Sukhapha and his followers were attacked by the Nagas at Khamyang on their way over Patkai. After his crossing over the Patkai, the Tai Khamyang were driven away to take refuge in Assam under the oppressions of Siukhanpha. It is that early settlement of the section of Noras who was subsequently known by that name. The Tai Khamyang, in the
Patkai, got divided into two groups namely the Maan Nam or Pani Nora (Low Land Nora) and Maan Loi or Dum Nora (Upper land Nora). This settlement lies near the great lake "The Lake Of No Return" (Nong Kheo Lok Yang). In the mid-eighteenth century, due to the criticism surrounding for the presence of a couple of Cobras in the lake and problems faced from the Kachins, the Tai-Khamyangs crossed over the Patkai hill and settled in a fertile valley of Arunachal Pradesh. It is said that they constructed a pagoda which is still present near the no return lake. In the later period, they maintained good relationships with the Tai-Khamtis and established villages in Tengapani area. During the rule of Ahom king Gaurinath Singha, they immigrants to Jorhat district of Assam. With regard to their earlier migration to Assam, it may be noted that some Noras had accompanied Swargadeo Sukhapha and later on their separate identities were merged with the name Khamyang. History bears testimony to the fact that in 1524 Swargadeo Chukungmong married the daughter of the Nora Raja and Nora Raja equally was honored with a Khamyang damsel. It is quite probable that some Noras might have accompanied the princess in 1576. Swargadeo Chukhamfa also married one Nora princess. The princess was accompanied by a Nora prince, a priest, and 1000 Nora people. ==Culture==
