Singhanavati

The Singhanavati (Thai: สิงหนวัติ; rtgs: Singhanawat) Kingdom was based along the river named Kok, in the Chiangrai Basin in northern Thailand. The ancient Lanna society of northern Thailand is considered more progressive than many other societies in other regions of the same period, in that the Lanna people recorded their history and social development. Records concerning cities in the Chiangmai and Chiangrai Basin have proved well-grounded. A large number of stone tools were excavated in this area. Settlements in this region are supported by Thai north chronicle and the record of Yonok-nagabundhu, which is about people migrating to settle in this region.

Sinhanavati Kingdom was seated on the river named Kok, which descends from the mountain in Fang District (Chiangmai), and runs into the Kong River at the east of Chiangsaen District (Chiangrai Province), from which the city itself was at a distance of about 3 kilometres (1.9 mi). This city was submerged below Chiangsaen Lake due to an earthquake.

The city is located in Chiangrai Basin, northern Thailand, where archaeological evidence has been found, such as ancient community sites, religious sanctuaries, and artifacts. The ruins of fifteen ancient cities have been found in various parts of Chiangrai.

Due to a disaster, Samantaraja of Pataliputra obliged all his people to follow him to the region of Bodhisaanluang. He built the city of Indrapath which he surrounded with a stone wall. His daughter married Kuruvamsa, the grandson of Samantaraja’s minister, who built the nearby city of Kururath.

When the king of Bodhisaanluang learned of the new settlements in his territory, he declared war against them, but eventually he was defeated.

Kuruvamsa began to reign and promoted both cities, Kururath–Indrapath as the capital of the new kingdom. Three other kings succeeded him: Sirivamsa, Indravamsa, and Indrapathom.
