JAH RASTAFARI. Nice summary of the history. Well Africans went to Jamaica but mainly as slaves taken there. I’ll have to research about the Ethiopians going to Jamaica , though come to think of it many Jamaicans have that Ethiopian facial characteristics.
If the story is very long, I just wanted to show the relationship between Rastafarians and reggae, if there were not many immigrants, they also came as slaves like most Africans when they were taken from their lands.
