Answer:
Ethnic cleansing
Step-by-step explanation:
After the fall of communism in 1990s, the provinces of Slovenia and Croatia declared independence. Major war broke with ethnic tensions between Croatians and Bosnian Muslims or Bosniaks. Major conflict began in 1992. Two communities that lived for years were against each other. Croats with the help of Serbia attacked Bosniaks resulting in mass execution, deaths, rapes and tortures.
Such a concept of systematically executing members of a particular community and race is known as Ethnic cleansing. History has witnessed several ethnic cleansing like the German Holocaust that took millions of Jews' lives. It leads to hatred towards an ethnic minority so much so that a mass execution seems morally correct.
