DehumanizationDehumanization is the denial of full humanity in others along with the cruelty and suffering that accompany it. A practical definition refers to it as the viewing and the treatment of other people as though they lack the mental capacities that are commonly attributed to human beings. In this definition, every act or thought that regards a person as "less than" human is dehumanization. Dehumanization is one form of incitement to genocide.
AryanismAryanism is an ideology of racial supremacy which views the supposed Aryan race as a distinct and superior racial group which is entitled to rule the rest of humanity. Initially promoted by racist theorists such as Arthur de Gobineau and Houston Stewart Chamberlain, Aryanism reached its peak of influence in Nazi Germany. In the 1930s and 40s, the regime applied the ideology with full force, sparking World War II with the 1939 invasion of Poland in pursuit of Lebensraum, or living space, for the Aryan people.
UltranationalismUltranationalism or extreme nationalism is an extreme form of nationalism in which a country asserts or maintains detrimental hegemony, supremacy, or other forms of control over other nations (usually through violent coercion) to pursue its specific interests. Ultranationalist entities have been associated with the engagement of political violence even during peacetime. The belief system has also been cited as the inspiration for acts of organized mass murder in the context of international conflicts, with the Cambodian genocide being cited as an example.
Ethnic hatredEthnic hatred, inter-ethnic hatred, racial hatred, or ethnic tension refers to notions and acts of prejudice and hostility towards an ethnic group to varying degrees. There are multiple origins of ethnic hatred and the resulting ethnic conflicts. In some societies, it is rooted in tribalism, and in other societies, it originates in a history of non-peaceful co-existence and the resulting actual disputed issues. In many countries, incitement to ethnic or racial hatred is a criminal offense.
