Answer:
South Sudan, of Christian black majority, fought for decades to become independent of Sudan, with an Arabized Muslim majority. The war against the north united the tribes of the south that, having disappeared the common enemy after independence, have returned to their ancestral rivalries.
Explanation:
The wars in Sudan are the longest in Africa. The first took place between 1963 and 1972, when the rebels of South Sudan rose up against the government of Sudan dominated by the Arabized elites. Although Sudan gave some autonomy to the south in 1972, it was not enough. The conflict resumed in 1983 with the creation of the Sudan People's Liberation Movement/Army (SPLM/A). In 2005, after a cruel war, the government of Khartoum, the capital of Sudan, signed the peace by granting the right to self-determination of the southern territories, with the exception of the Blue Nile and Southern Kordofan States.
