Sisavang Vong, born Prince Khao on 14 July 1885, was a significant figure in Lao history, serving as the last ruler of the Kingdom of Luang Prabang and the founding king of the Kingdom of Laos. He ascended to the throne at the young age of eighteen following the death of his father, embracing the courtesy name Sisavangvong in accordance with Lao tradition.
His reign began during a time of French colonial authority, and he was born in the Golden Palace of Luang Prabang. Throughout his rule, he expanded his influence over other Lao kingdoms and oversaw the construction of a new royal palace, symbolizing his commitment to the modernization of his realm.
In late nineteen forty-five, Sisavang Vong briefly ruled as the king of the Japanese puppet state of Luang Prabang. However, his pro-French stance led to his dethronement by the Lao Issara. Despite this setback, he was reinstated as monarch by the French in nineteen forty-six, marking a historic moment as it was the first time in nearly two and a half centuries that a Lao monarch governed the entirety of Laos.
