What is the name of Pol Pot's ethnic cleansing program shown in the film "The Killing Fields" that caused the death of more than 2 million Cambodians?

The Cambodian Killing Fields were a number of sites in Cambodia that were part of the Khmer Rouge Peace Program. This was a program (plan for ruling the country) where collectively more than two million people were killed and buried. The fatal plan actions were taken by the Khmer Rouge regime during its rule of the country from 1975 to 1979, immediately after the end of the Cambodian Civil War (1970–1975).

The mass killings that took place in the country were regarded as part of a broad state sponsored genocide (the Cambodian genocide). At that time, Cambodia could not afford to have any more war. The people had been suffering far too many years. It was then hoped that the Cambodian leaders would get together and work for the good of the country. After enduring pain for such a long time, the Cambodian people deserved to live without fear and in peace. It was hoped that the new government (the Khmer Rouge) would let the people enjoy a new life. This was not the case.
