The Khmer Krom people have been in existence in this part of the peninsula since the beginning of the first century. They have sacrificed their lives to hold on to the territory since then. The territory was immense compared to the Khmer population at that time, creating opportunities for expansionist neighbours to invade. For this reason, after the Vietnamese exterminated the Kingdom of Champa; they used all kinds of pretexts and tactics to move their people to Kampuchea Krom. Since the French colonial departed Indochina in 1954, after nearly one hundred years (1867-1954) of domination on this land, Kampuchea Krom has been placed under Vietnamese control. The Khmer authority had filed complaints against this criminal act, but the French National Assembly chose to ignore them.
Besides the Vietnamese, there are Cham and Chinese living in Kampuchea Krom. The Khmer Krom are out numbered by their "invaders" and "rulers", who once asked the Khmer Krom for asylum or migration only. About seventy percent of the Vietnamese and ninety-five percent of the Chinese live in the cities and fill most of important jobs in government and business. The Khmer Krom, live through out the country, especially, in the Mekong delta.
