According to the villagers Dei Ey was founded in 1914 with the name Ta Bo village. This group was 1 kilometre south of the present location. In that time people built houses in two rows along the road which was connected from Sen Monorom to Kho Nek.
In 1919, the French camped at that place and they changed the name from Ta Bo village to Dei Ey. During 1970s, this area became a battlefield between revolutionists and Khmer Republic soldiers. From 1972-1975, the area suffered from the bombs from American air troops that made the villagers living in Dei Ey flee to the other places such as to Keo Seima district, Krang Teh subdistrict, Srei Tom village in Kho Nek district and some to Vietnam.
In 1988, there were around 300 troops of Brigade N.88 camping in Dei Ey till 1993, then they changed their name to Brigade N.2. At the same time, there were 15 provincial police officers settling there. Until 1999 those soldiers and police officers were forced to leave Dei Ey and sent to border 103 which was along Cambodia-Vietnam territories. From 1989-1992 people started to move back to this area but there was not enough security.
In 1993 there were 7 families living in this village. From 1995-2007 this area was safe enough and people came to live and do some farming. Also, the government built schools, educated about the law, and developed the place and improve their living standard. At the same time, the population increased remarkably and the new comers especially Cham and Khmer who were from Kompong Cham, Kompong Thom, Prey Veng, Ta Keo, Svay Reang and Kratie province. In 2008, there were 118 families, in total 490 people with 241 females.
