Originating on the Pontic Steppe in Eastern Europe 6,000 years ago, the Indo-European language family is far and away the most widespread language family in the world. First they spread out of their Eastern European urheimat across Eurasia from Iceland to Bangladesh, and then with the European Age of Exploration spread worldwide, to where in the present day around half of the world's populations speaks an Indo-European language natively. However, it didn't spread everywhere, and one of the places it didn't reach was Sub-Saharan Africa. With the exception of the Dutch daughter language of Afrikaans, there is no Indo-European language indigenous to Sub-Saharan Africa (and even calling that indigenous is stretching it), which is the subject of today's AHC. You will devise some way in which an homegrown Indo-European language could become natively spoken in Sub-Saharan Africa before the colonial era. I've got a few ideas for how this could feasibly happen myself, but I'm gonna pass it on to you guys first.
