Muang Sua

700 CE – 1353 CE (approx.) · capital Muang Sua

The early Tai-Lao principality at the meeting of the Mekong and Nam Khan, the site of Luang Prabang and the cradle of the kingdom of Lan Xang.

Origins

Lao chronicles say Khun Lo, a son of the mythical Khun Borom, took Muang Sua from its earlier inhabitants and founded a dynasty there, traditionally in the 8th century. The town, also called Xieng Dong Xieng Thong, occupied the site of present-day Luang Prabang, which had earlier been settled by Mon-Khmer peoples.

Rule and society

Muang Sua was a Tai muang, a valley principality ruled by a chief whose authority rested on rice lands, river trade and ties to other Tai rulers. Lao tradition records a long line of rulers, but few are attested outside the chronicles. In the late 13th century it seems to have come under the influence of Sukhothai.

Decline and legacy

In 1353 Fa Ngum, a Lao prince raised at the Khmer court, captured Muang Sua with Khmer support and made it the capital of his new kingdom of Lan Xang. The city was renamed Luang Prabang after the Phra Bang Buddha image was installed there in the 16th century.

Few sources survive for this state; details are uncertain.
