Black Irish comes from social and political biases as well as genetic history. In the 1800s, many Caucasian people believed that the Irish were somehow related to Africans. Africans and individuals of very dark features were held in distaste and considered to be inferior peoples. Therefore, the term Black Irish was born and upheld. In 1862, John Beddoe, an esteemed ethnologist, published Races of Britain in which he described those of Celtic descent as having features similar to those of African descent.
