Examine three factors that historically have contributed to genocide.

Race, Nationalism, and religion.  

Explanation:

The reason for the appearance of the genocide can differ from another. Some of the genocides we know of them today are the Nazi Holocaust, in Armenians and Rwanda. The genocide creates a situation of the removal of ethnic and minority groups from society as they are term as unwanted populations. The Armenian genocide happened with the rising of nationalistic force in the Ottoman Empire by the Young Turks as Armenians consider as an unwanted cultural minority by recreating a pure nationalism. The Rwandan genocide caused by a political struggle between the Tutsi and Hutu. Nazi Germany followed the ideology of purification in a race(supremacy) that led to isolating the Jews because of their religion.
