The idea of a black Hannibal had no particular geographic reference because Hannibal courses north Africa. What mattered is the biblical injunction and the fact that the Bible is both a record of history and understood to be a predictor of the future simultaneously. And so the predictor is this idea that Ethiopia shall stretch forth their arms. Now that's Ethiopianism initially had very little to do with Ethiopia itself except for the fact that Ethiopia was or the region we know today as Ethiopia. But what it did do was it created an exception even in the minds of European Christians because Ethiopia, which wasn't a nation yet, had adopted Christianity before any other part of Africa.
