Japanese occupation and Lao Issara: 1941–1957

Phetsarath played a dominant role in Lao politics before and after the Japanese occupation. He was the Prime Minister of Luang Phrabang, beginning in August 1941,

, including Laos. On 8 April 1945 King Sisavang Vong had declared–under Japanese pressure and at the urging of Phetsarath–that his kingdom was no longer a French protectorate. Shortly thereafter however, on 28 August 1945, Japan surrendered.
In the ensuing power vacuum, Phetsarath moved to unite the southern provinces of Laos with Luang Phrabang. This put him at odds with the pro-French King Sisavang Vong, who had agreed with the French that he intended to have the country resume its former status as a French colony. Phetsarath sent a telegram to all Laotian provincial governors notifying them that the Japanese surrender did not affect Laos' status as independent and warning them to resist any foreign intervention. On 15 September Phetsarath declared a unified Kingdom of Laos which led the King to dismiss him from his post as Prime Minister on 10 October.
Phetsarath and other Lao nationalists then created the Lao Issara (''Free Laos'') movement and took control of the country. The Lao Issara provisional assembly under Phetsarath proclaimed the deposition of the King and appointed Phetsarath as "Head of State". As the French retook control of Laos, Phetsarath fled in April 1946 to Thailand

He was offered an official government residence in Vientiane, but preferred to stay in his villa, Xieng Keo, in Luang Prabang with his Thai consort, Mom Aphiphorn. In early October 1959 the Phoui Sananikone Government decided to use Phetsarath's official residence in Vientiane as the new prime minister's office. They vacated the building and shipped his personal belongings by boat to Luang Prabang, which upset him immensely.
