I have a hard time understanding sudan, what happened to them/how did it start? what's going on both north and south? Do all ethnic groups hate eachother? What is the main ethnic group elites?
British sent in Christian missionaries into the South, to make sure it didn't become Muslims like the North. It started after the Brits left.
Yes, we do have some tribal problems in the Sudan, hence the Darfur war. North are Muslims, but it was our rulers wanted to implement Sharia on them. North Sudani people are Arabized, mixed with some other shit. Southern Sudanese people are Nilotic, christian Africans.
The last question, I would say the Jaali3is in Sudan are the main group elites in the North, and in the South its the Dinka and Nuer
