Chao Anouvong was installed as a vassal king of Vientiane by the Siamese. He encouraged a renaissance of Lao fine arts and literature and improved relations with Luang Phrabang. Under Vietnamese pressure, he rebelled against the Siamese. The rebellion failed and Vientiane was ransacked. Anouvong was taken to Bangkok as a prisoner, where he died.
A Siamese military campaign in Laos in 1876 was described by a British observer as having been "transformed into slave-hunting raids on a large scale".
