Kingdom of Vientiane
During the rule of King Anouvong of the Kingdom of Vientiane, Anouvong placed his son Prince Nyô on the throne of Champassak. During King Anouvong's rebellion against Siam, the former royals of Champassak started a rebellion against Prince Nyô while he was fighting against Siamese forces in Issan. Returning to Champassak, Prince Nyô saw a rebellion taking place and barely escaped out of the city. This escape was cut short after the former rulers tracked down Prince Nyô and handed him over to the Siamese. The King of Siam returned the former royal family to rule over Champassak.
