Ethnicity is key to our identity. It can be formed around a variety of nuclei- historical ties, national origin, language, religion, or any admixture thereof. Ethnicity creates a feeling of belonging to a group. Ethnicity, of course can also be a source of exclusion to those who do not belong to the group that holds power in a place. Discrimination and prejudice often have a root in ethnicity, although other factors, like economics generally play a part as well. Race (and racism) are closely related to ethnicity, in that both ethnicity and race have been used to separate people, and some ethnicities can be associated with particular races. The next chapter also deals somewhat with human identity and delves further into nations and nationality.
