Ethnic hatred, inter-ethnic hatred, racial hatred, or ethnic tension refers to feelings and acts of prejudice and hostility towards an ethnic group in various degrees.
There are multiple origins for ethnic hatred and the resulting ethnic conflicts. In some societies it is rooted in tribalism, while in others it originates from 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. Often ethnic conflict is enhanced by nationalism and feeling of national superiority—for which reason inter-ethnic hatred borders with racism, and often the two terms are conflated.
Ethnic hatred has often been exploited and even fueled by some political leaders to serve their agenda of seeking to consolidate the nation or gain electorate by calling for a united struggle against a common enemy (real or imaginary).
An example for ethnic hatred is the hatred of the Romani people in Europe. The Romani people, also known as Gypsies are the marginalized and persecuted ethnic groups in Europe.
