Chantharath

Chao Chantharath (; 1799–23 August 1870) also known as Chandakumara, Chanthakuman, Chantharad or Tiantha-koumane, was king of the north-central Lao kingdom of Luang Phrabang from 1852 to 1870. During his reign, the King of Siam controlled the foreign affairs of the kingdom, but allowed Chantharath control over local laws and government.

Chantharath was the second son of Manthathurath. He succeeded his elder brother Sukkhasoem in 1852 after his brother's death. During his reign, the kingdom was confronted by serious local, regional, and international threats. In 1864, Haw rebels raided the country. He freed the Principality of Xiangkhouang (Muang Phuan) from Vietnamese and Haw rebels. In 1828, the Siamese king Mongkut returned the Phra Bang Buddha to Luang Phrabang. Chantharath died of malaria in 1870. In 1872, Chantharath's brother Oun Kham succeeded him on the throne.
