Final answer:
Sudan's civil war has largely been driven by conflicts between Muslim Arabs in the north and Christian and animist Africans in the south, affected by historical, ethnic, and religious factors as well as colonial legacies.
Step-by-step explanation:
Sudan's lasting civil war can be attributed to conflicts primarily between Muslim Arabs and Christian and animist Africans. The African Transition Zone passes through Sudan, separating the Arab-Muslim dominated north from the predominantly African-Christian south. Decades of civil strife have ensued, with the north conducting raids and enforcing slavery upon southern villages until a 2005 peace agreement. This conflict notably differed from the strife in Darfur, which although involving Muslims on both sides, was largely an ethnic conflict between those of African background and self-identified Arabs.
Moreover, civil wars in Africa have often been exacerbated due to artificial colonial borders and poor governance. The ethnic conflict seen between the Hutus and Tutsis in Rwanda, which led to the 1994 genocide, is a stark example of the continent's struggles with postcolonial power dynamics and ethnic divisions. This situation does not directly relate to Sudan's circumstances.
Ultimately, the ongoing turmoil in Sudan is rooted in a complex interweaving of historical, ethnic, and religious factors, influenced by colonial legacies and competition for resources.
