In 1868, after having annexed South Vietnam as a colony
and having turned Cambodia into a French protectorate, the French
send an initial expedition to Laos to investigate the Mekong
trade route to China.
In 1886 France receives permission from Siam largely ruling
Laos, to install a vice consulate in Luang Prabang. In 1887,
Siam, anticipating French expansion, vacates large parts of Laos.
In 1893 France declares the Mekong the official
border between Laos and Siam. Might is right; Siam accepts the
unilateral decision of big-gun France. Laos officially becomes
a French protectorate.
However, France has only limited interest in her new possession.
Paris sends Vietnamese officials to Laos to set up an administration
but does little to develop the Laotian economy.
In September 1940 , after France is invaded by Germany,
Japanese troops occupy Indochina without meeting any resistance.
Officially the word is that the French colonial power leaves all
military installation for the Japanese troops to use; in exchange
the French colonial administration remains in office. Therefore
the years of World War II bring less destruction to Laos than,
for instance, to the fiercely contested Southeast Asian states
of Burma and the Philippines.
In East Asia, World War II ends August 14, 1945, with the
capitulation of Japan. Subsequently, France tries to re-establish
herself as colonial power in Cambodia, Vietnam and Laos.
On September 1, 1945, Laos declares its independence.
France refuses to accept this, and retaliates by sending troops
into Laos. A guerilla war against the French colonial power starts.
