Rastafaris come from Ethiopia, note that in the word Rastafari you have Ras (Province governor in Ethiopia)) and Tafari (name of the governor) named later Halie Selassie, Emperor of Ethiopia until 1975 (I think). This guy claimed to be descendent of the dinasty of Salomon coming from Israel, and Rastafaris had Halie Selassie as their god. Also there are still in Ethiopia a few Jew tribes.
I explained this as exact as I remember, but I don't remember very well, so I may be wrong, or missed something, but more or less, is like this...
Anyone to explain it better than I?
