There is little evidence of what part of eastern Africa the Zanj came from, for the name is here evidently used in its general sense, rather than to designate the particular stretch of the coast, from about 3°N. to 5°S., to which the name was also applied.” - Ghada Hashem Talhami "The Zanj Rebellion Reconsidered". The International Journal of African Historical Studies. 10 (3): 443–461. (1977). It has often been said that the greatest invention of all time was the sail, which facilitated the internationalization of the globe and thus ushered in the modern era. Columbus’ contact with the New World, alongside European maritime contact with the Far East, transformed human history, and in particular the history of Africa. It was the sail that linked the continents of Africa, Asia, and Europe, and thus it was also the sail that facilitated the greatest involuntary human migration of all time.
