This time Chinese rule is shortlived. Rebel leader Le Loi builds a resistance force and defeats the Chinese in 1428. He takes the thrown and establishes a dynasty that will last until 1788, although once again internal dissent convulses the country, resulting in a partition in 1545. The southern 'Nguyen' continue their conquest of coastal territories and the Mekong Delta, encroaching into Kampuchea-Krom (today's southern Vietnam), which is inhabited by the culturally distinct Khmers (today's Cambodians). In the north the 'Trinh' consolidate their rule.

The country is reunited in 1786 during the 'Tay Son Rebellion', a period of war and instability that ends in 1802 with the enthronement of Gia Long, an emperor indebted to both the French and the Chinese for his rise. Gia Long changes the name of the country from Dai Viet to Nam Viet but is required by the Chinese to invert this to Viet Nam. French and European influence now becomes a growing factor in Vietnamese politics. By the middle of the 19th Century the French are planning for greater interference.

By 1862 the French have forcibly seized Kampuchea-Krom territory in the south and signed the 'Treaty of Saigon' granting them trade concessions and giving them control of three provinces. The entire country is made a French protectorate in 1883.

1949 - On 1 July a French-sponsored Vietnamese Government is established in Saigon. The territory administered by the new government incorporates Kampuchea-Krom (Cochin-China), which is largely inhabited by culturally distinct Khmers (Cambodians). The Khmer-Krom had been hoping for independence, and the inclusion of their ancestral lands into Vietnam will create ongoing tensions that to this day remain unresolved

‘Centre and Periphery’: The Ambiguous Life of the Khmer Kampuchea Krom in Postcolonial Southeast Asia

Marc Askew, Victoria University of Technology, Melbourne

This paper investigates the construction and representation of ethnicity and place among the Khmer Krom minority of Southern Vietnam and its diaspora. The "Kampuchea Krom" as a territory, has played a crucial symbolic role in Khmer nationalist (fundamentally anti-Vietnamese) narratives (from the Sihanouk period through to the Pol Pot regime). But the people of this territory have occupied an ambiguous place in the postcolonial histories of Cambodia and Vietnam. The Khmer Krom, who occupy the Mekong Delta region, are a particular socio-cultural fragment of a larger cultural-territorial formation which was progressively appropriated into the neighboring states of Vietnam and Siam (17th–19th centuries), taken over by a European colonial power (France 19th century–1954), a post-colonial Vietnamese republic (1954–1975) and then a socialist state (1975 to present). Khmer Krom political and cultural mobilizations in the twentieth century (from covert everyday resistance to overt politico-ethnic opposition) were cumulatively shaped both by the pre-colonial past and developments during the period of French administration and then a combination of mounting local and external changes and pressures generated by the post WWII politico-ideological environment. French decolonization, the various nationalist independence movements, the establishment of the states of Cochinchina (1949) then South Vietnam (1954) and the escalating U.S. involvement in Vietnam and Cambodia from the late 1960s, have all resonated through the communities of the Kampuchea Krom and, its growing diaspora. This paper focuses on the critical period spanning 1945–1975, when Khmer Krom ethnonationalism was militarized and fictionalized in the context of South Vietnamese and Cambodian politics and U.S. intervention.

"The Khmer Krom, who occupy the Mekong Delta region, are a particular socio-cultural fragment of a larger cultural-territorial formation which was progressively appropriated into the neighboring states of Vietnam and Siam (17th–19th centuries)"

That's all I need to know. Thanks for the article saying it belonged to Vietnam since the 17th-19th century. Which also proves my Yale article right with Vietnam controlling that area since 1750. So much for that 1949 thing. Now will you Khmer Krom stop your attempts to try steal our land by making up lies and tricks???

Here's what the Khmer Krom are demanding according to this UNPO statement.

http://www.unpo.org/news_detail.php?arg=30&par=14

"Therefore, on behalf of the Khmer Krom people and the Khmers Kampuchea Krom Federation, UNPO would like to appeal to the government of the Socialist Republic of Vietnam to consider the following requests:

1. Decolonize Kampuchea-Krom, Motherland of the Khmer-Krom people, composed of 68,600 km2 , forming the southernmost part of present Vietnam.
2. Place the Kampuchea-Krom territory under the United Nations control in accordance with the Charter of the United Nations, Chapter XI, Chapter XII, and Chapter XIII, in order to create a free and fair political environment allowing the Khmer- Krom people to exercise their right to self-determination.:

HA HA HA HA HA HA HA Do they expect us to just give away South Vietnam to the UN so they can give it to the Khmer Krom. 68,600 square KM of our land that has been ours since 1750, we are gonna boot out millions of Vietnamese who have lived and made the land prosperous and made Saigon the most booming city in Vietnam as well. Most of Vietnam's rice comes from the Mekong Delta, like we are just gonna be stupid enough to just give away something that rightfully belongs to Vietnam.

Yeah we are gonna kick out millions of Vietnamese who live in Saigon the most populous city in Vietnam and the millions of Vietnamese who live in South Vietnam rural areas just for the 1 million Khmer Krom who don't have any rights to the land as the Vietnamese.
