Extended data:
The racial classification of blacks mainly includes Sudanese blacks, Bantu blacks (both of which account for the vast majority of African blacks), Koisan blacks, Cuscito blacks (mixed-race) and Australian aborigines.
Before and during the Middle Ages, they were mainly distributed in sub-Saharan Africa. Later, because of imperialism and mercantilism in European countries, a large number of blacks were forced to be sent to South America and North America as slaves.
Negro was once used as a name for a black man in English, but it was originally a "black man" in Spanish, but it had a strong contempt. Some black groups with a long history still use this word today.
For example: African American University Foundation. The common name of American media is: African-Americans. Black (black) is also acceptable, and nigger (low-level) is completely derogatory. However, some black people also use this word to address each other.
