Sisavang Vatthana
Prime Minister of Laos (1907-1978)

Sisavang Vatthana (Lao: ພຣະບາທສົມເດັຈພຣະເຈົ້າມະຫາຊີວິຕສີສວ່າງວັດທະນາ) or sometimes Savang Vatthana (full title: Samdach Brhat Chao Mavattaha Sri Vitha Lan Xang Hom Khao Phra Rajanachakra Lao Phengdara Parama Sidha Khattiya Suriya Varman Brhat Maha Sri Savangsa Vadhana; 13 November 1907 – 13 May 1978) was the last king of the Kingdom of Laos and the 6th prime minister of Laos serving from 29 October to 21 November 1951. He ruled from 1959 after his father's death until his forced abdication in 1975. His rule ended with the takeover by the Pathet Lao in 1975, after which he and his family were sent to a re-education camp by the new government.
Early life
Savang Vatthana was born on 13 November 1907 at the Royal Palace of Luang Prabang, the son of King Sisavang Vong and Queen Kham-Oun I. He was the second of five children along with Princess Khampheng, Princess Sammathi, Prince Sayasack, and Prince Souphantharangsri. He was also a distant cousin of Prince Souvanna Phouma and Prince Souphanouvong. At the age of 10, Prince Savang was sent to study in France. He attended a lycée in Montpellier and obtained a degree from École Libre des Sciences Politiques (now called Sciences Po) in Paris, where French diplomats were trained. The young heir continued his studies in France, and after a decade overseas, he could no longer speak Lao. Upon his return, he had to be instructed by a palace functionary for years.
On 7 August 1930, he married Queen Khamphoui and they had five children, Crown Prince Vong Savang, Prince Sisavang Savang, Prince Sauryavong Savang, Princess Savivanh Savang, and Princess Thala Savang.
This brief starts where responsible research should: with the source description of “Sisavang Vatthana” as prime Minister of Laos (1907-1978). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as prime Minister of Laos (1907-1978). Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q379797. VIAF identifies the subject as 23877510. The Library of Congress control number is n97019347. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1907, 1978, 1951 and 1959.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
