Ethnic cleansing are all forms of attempts of elimination of a particular ethnic group. Ethnic cleansing may take place in subtle forms as well as radical forms. Ethnic cleansing may take place mentally or physically.
Ethnic cleansing usually takes place to homogenize the population of a given particular territory or make the dominant ethnic group(s) culture omnipresent.
Ethnic cleansing is usually accompanied by efforts to remove physical and cultural evidence of the targeted group in the territory through the destruction of homes, social centers, farms, and infrastructure, through the desecration of monuments, cemeteries, and places of worship.
1. Enforced - Ethnic cleansing could be enforced. Such as the state power could use institutionalized force to conduct ethnic cleansing. The dominant group with the aim of ethnic cleansing may form their own army to create an enforcing state.
For example: the government declares use of X language illegal, use of X language invalid for administrative purposes.
2. Systematic - The systematic forms of ethnic cleansing takes a well planned or a step-wise process to achieve the wider goal of ethnic cleansing.
