Chao Anouvong, or regnal name Xaiya Setthathirath V, , led the Lao rebellion (1826–28) against Siam as the last monarch of the Kingdom of Vientiane. Anouvong succeeded the throne in 1805 upon the death of his brother, Chao Inthavong, Xaiya Setthathirath IV, who had succeeded their father, Ong Bun or Phrachao Siribounyasan Xaiya Setthathirath III. Anou was known by his father's regnal number until recently discovered records disclosed that his father and brother had the same regnal name.
