There was a book written by a black american economist about how African-American culture is actually a hold over from 18-19th century southern US redneck culture which was itself a hold over from some poor Scottish and some northern English farmer towns who emigrated en masse to the south.
These people became wealthy enough to buy slaves and black people grew up living among their culture, eventually adopting it, with their own adaptations of course, that persisted. Once they became free they eventually brought it with them as they moved into northern inner cities where it became a symbol of “blackness”. It has survived longer in it’s original form thanks to US social stratification that still exists today in many forms – while the middle/upper southern white culture has more generally merged with the north/west.
So we can still thank Europe for at least a part of black culture.
