Sudans many years of civil war have resulted from conflicts between
Alinara [238K]

Answer:

Sudans many years of civil war have resulted from conflicts between "Muslim Arabs, and Christian and animist Africans. "

Explanation:

Religion is the essential effect in Sudan’s civil war. The North, with most of Sudan's land and inhabitants, is Muslim and Arabic-speaking, and their religion and language are both important for their individuality. On the other hand, the South´s individuality is indigenously African, with Christian and Western influences. Sudan's first civil war was fought between the Arab-led Khartoum government in the north and rebels in the largely Christian and animist south. Southern rebels were fighting for regional autonomy and representation in the government. A peace agreement was signed in 1972 that granted semi-autonomy to the south.
