The Khmer Krom (Khmer: ខ្មែរក្រោម, Vietnamese: Khơ Me Crộm) are indigenous Khmer people in southern Vietnam. In the Khmer language, Krom means "lower" or "below", as it refers to the lower reaches of the Mekong Delta, south of Cambodia proper. In the Vietnamese language, they are known as Khơ-me Crộm or Khơ-me dưới, which literally means "Khmer from below", a translation of the Khmer term.
The Khmer Krom are ethnic Khmer who inhabit Kampuchea Krom, an area in southern Vietnam that was once part of the Khmer Empire. Funan may have been the referred to in ancient Indian texts. Among the Khmer Krom the belief is held that they are the descendants of ancient Funan, the core of Suvarnabhumi, which covered a vast extent of Southeast Asia including present day Cambodia, southern Vietnam, Thailand, Laos, Burma, Malaya, Sumatra and other parts of Indonesia. 
According to Vietnamese government figures (1999 census), there are 1,055,174 Khmer Krom in Vietnam. Estimates vary considerably, with up to 7 million reported to Taylor (2014) in his The Khmer lands of Vietnam.
Absorption of the Mekong Delta by Vietnam
A weakened Khmer state after repeated warfare with Siam in the 17th century left the Mekong Delta poorly administered. Concurrently Vietnamese refugees fleeing the Trịnh–Nguyễn War in Vietnam pushed into the area. Cambodian king Chey Chettha II (1618–1628) in 1623 officially sanctioned the Vietnamese to operate a custom house at Prey Nokor, then a small fishing village. The settlement grew steadily as a major regional port, attracting even more settlers.
The Nguyễn Lords of Huế in 1698 commissioned Nguyễn Hữu Cảnh, a Vietnamese noble, to organize the territory along Vietnamese administrative lines, thus by de facto detaching it from Cambodia and joining it to Vietnam.
With the loss of the port of Prey Nokor, then renamed Sài Gòn, Cambodia's control of the area grew increasingly tenuous while increasing waves of Vietnamese settlers to the Delta isolated the Khmer of the Mekong Delta from their brethren in Cambodia proper. By 1757, the Vietnamese had absorbed the provinces of Psar Dèk (renamed Sa Đéc in Vietnamese) on the Mekong itself, and Moat Chrouk (Vietnamized to Châu Đốc) on the Bassac River. Cambodia was cut off from direct access to the South China Sea at that point. Left within the borders of Vietnam were large pockets of Khmer people, now known as the Khmer Krom.
Khmer nationalist Son Ngoc Thanh (1908–77) was a Khmer krom, born in Trà Vinh, Vietnam. Thanh was active in the independence movement for Cambodia. With Japanese support he became the prime minister of Cambodia in March 1945 but was then quickly ousted with the return of the French later that year. Widely supported by the Khmer Krom during the First Indochina War, Thanh's role faded in Vietnam after 1954 as he became more embroiled with politics in Cambodia proper, forming an opposition movement against Prince Sihanouk.
During the Vietnam War and direct American involvement between 1964 and 1974, the Khmer Krom were recruited by the US military to serve in MIKE Force. The force fought on the side of South Vietnam against the Viet Cong but in time the militia regrouped as the "Front for the struggle of Kampuchea Krom" (French: Front de Lutte du Kampuchea Krom). Headed by a Khmer Krom Buddhist monk, Samouk Sen, the group was nicknamed the "White Scarves" (Khmer: Kangsaing Sar; Vietnamese: Can Sen So) and allied itself with FULRO against South Vietnam.
After the Fall of Saigon in 1975 and the Communist take-over of all of Vietnam, the Kampuchea Krom militia found itself embattled with North Vietnamese Army. Many of the fighters fled to Khmer Rouge controlled Cambodia (Democratic Kampuchea) hoping to find a safe haven to launch their operations inside Vietnam. The "White Scarves" arrived in Kiri Vong District in 1976, making overture to the Khmer Rouge and appealing to the leader Khieu Samphan directly for assistance. The force was disarmed and welcomed initially. Subsequent orders from the Khmer Rouge leadership however had Samouk Sen arrested, taken to Phnom Penh, tortured, and killed. His force of 67 Khmer Krom fighters were all massacred. During the following months, some 2,000 "White Scarves" fighters crossing into Cambodia were systematically killed by the Khmer Rouge.
In the late 1970s, the Khmer Rouge regime attacked Vietnam in an attempt to reconquer the areas which were formerly part of the Khmer Empire, but this military adventure was a total disaster and precipitated the invasion of Cambodia by the Vietnamese army and subsequent downfall of the Khmer Rouge, with Vietnam occupying Cambodia.
Many independent NGOs report that the human rights of the Khmer Krom are being violated by the Vietnamese government. Khmer Krom are reportedly forced to adopt Vietnamese family names and speak the Vietnamese language.
Unlike other minority people groups in Vietnam, the Khmer Krom are largely unknown by the Western world, despite efforts by associations of exiled Khmer Krom such as the Khmers Kampuchea-Krom Federation to publicize their plight with the Unrepresented Nations and Peoples Organisation. No Western government has yet raised the matter of the Khmer Krom's human rights with the Vietnamese government.
