Muang Singha was rarely known, it was a marginal traditional state with sovereignty using and relying to the bigger states which were Burma, Siam, and China; depending on political condition. Sometimes, this town might be called “Muang Sam Fai Fah Jao Ar-nanikhom. Afterwards, England took over the entirety of Burma and France invaded Indo China area. After Chiang Khang kingdom was separated, England took the right area of Khong River while France took the left so Muang Singha became a part of Laos since that day. On the later time, Chao fah Ong Kham, the last king of Muang Singha, failed the rebel against the western invader; then escaped to live the rest of his life in Chiang Rung. (From Wasin Oonjanam)
