Black African tribes in the Sudan have suffered for a long time under Islamic regimes. Sudan claims to be an Arab Country, but you will never see Arabs starving in the street, on Beja, Fur, Nuba, and Fallata ethnic groups. Arabs now make up 70% of the population of Sudan, however prior to the independence of South Sudan in 2011, Sudanese Arabs made up only 40% of the population.
The Sudan is one of the poorest Countries on this planet, while possessing vast natural resources like gold, oil, and fertile land.
