Ethiopia has had its “ups and downs.” It had a majority Christian population at different times dating back to the time of the Apostles. Italy wanted to conquer it in the 30’s because it had some wealth and upside potential. I can suppose that a fair amount of trouble now is with invaders of a certain religious cult.
According to the 2007 National Census, Christians make up 62.8% of the country’s population (43.5% Ethiopian Orthodox, 19.3% other denominations), Muslims 33.9%, practitioners of traditional faiths 2.6%, and other religions 0.6%
