Explanation: In the 19th century AD, Europeans flooded inland into the continent of Africa, formerly largely closed off to them by difficulty of travel and supply, seeking to colonize and, secondarily, to convert to Christianity whomever they could find. The African country of Ethiopia, however, which retained its independence in the face of 19th century European aggression, had been Christian for longer than most of Europe had been - Ethiopia had adopted Christianity in the 4th century AD!
