Answer:
Khmer Rouge took over Cambodia and persecuted its enemies.
Step-by-step explanation:
Genocide is termed as the intentional killing of a group of people by another, a more superior group who thinks that the others are an obstacle for their development. These killings led to a mass murder of people, generally based on their ethnic or racial backgrounds.
The genocide in Cambodia was led by the Khmer Rouge under the leadership of Pol Pot who worked towards "re-educating" the people from western influence. The party took over the nation and began persecuting its enemies. During this genocide, specific ethnic groups were rounded up and killed in mass numbers, using pickaxes which became famous as "the killing fields". Such type of genocide is also called as ethnic cleansing, a specific removal of a particular ethnic group.
