All such cases of pogroms, ethnic cleansing and so on in recorded human history, happened because of systems that openly, tacitly or implicitly accepted or promoted racist views, laws and sentiments.

In others yet, the system (by extension the military and others directly under command of the system) directly perpetrated these acts.
