Hailemariam Desalegn's surprise resignation came after sustained anti-government protests across this vast East African country. While the government considers who will take his place, it's imposed a state of emergency for the next six months. Ethiopia is the second most populous country in the African continent with 100 million people in more than 40 ethnic groups.

Tigrayans account for just 6 percent of the population but they dominate politics and the security forces. It's a 25-year-old arrangement but one that is causing a great deal of resentment among the other groups. So, what's next for Ethiopia?
