In 1819 Anouvong rushed to suppress a rebellion in the Kingdom of Champasak, led by a charismatic monk, who had caused the ruler to flee to Bangkok. Anouvong's son Nyô led an army south from Vientiane and easily suppressed the uprising. As the king of Champasak had died, Rama II of Siam appointed Nyô the new ruler of Champasak. Anouvong had succeeded in uniting two of the three Lao kingdoms under his control. Also that year, Anouwong ordered the construction of Wat Si Saket, which was completed in 1824. The temple was a major statement of his authority, since it was oriented so that when Anouvong's vassals came to pledge their annual allegiance, they physically turned their backs on Bangkok.
