Not much data about that time period. I would say war between Vietnam and Thailand after the Khmer Empire fell apart in 1431. War took place form 1431 to 1863, then Cambodia asked for French Protection in 1863. Cambodia got independence in 1953. Then peace for a while, again another war from 1975-1979. The beginning of 1980s considered the starting point of stable-peaceful-era for Cambodia. Such a country to be sympathy for.

Because of Cambodia had many wars since the past. The dark age(1593-1863), this period Cambodia got in control by Thailand, Laos, and Vietnam. French Colonial Rule(1863-1953), so much threat from the neighbor, Cambodia asked France for protection. Japanese Occupation of Cambodia(1941-1945), France still remained controlled over Cambodia while Japan occupied in Cambodia. Cambodian Genocide or Khmer Rouge(1975-1979), million Cambodians were killed by Khmer Rouge and starvation. Cambodian-Vietnamese War(1975-1989), after the Khmer Rouge lost its power in controlling Cambodia, it came back to fight Vietnamese. And today Cambodian President is under control of Vietnam. Cambodia is also in developing situation.
