Outline of Vietnam
Vietnam was under Chinese control for a thousand years before becoming a nation-state in the 10th century. Successive dynasties flourished along with geographic and political expansion deeper into Southeast Asia, until it was colonized by the French in the mid-19th century. Efforts to resist the French eventually led to their expulsion from the country in the mid-20th century, leaving a nation divided politically into two countries. Bitter fighting between the two sides continued during the Vietnam War, ending with a communist victory in 1975.
Battles of Bouamlong
Beginning in 1946, France fought the Viet Minh insurrection in French Indochina, including the Kingdom of Laos. When it lost that war, Laotian neutrality was established in the 1954 Geneva Agreements. When France withdrew most of its military in conformity with the treaty, the United States filled the vacuum with purportedly civilian paramilitary instructors. A North Vietnamese-backed communist invaded during the opium harvest season of 1953. It settled in northeastern Laos adjacent to the border of the Democratic Republic of Vietnam.
