Final answer:
The conflict in Sudan arises from ethnic and religious identity differences, exacerbated by the country's colonial history and the African Transition Zone dividing the Arab-Muslim North and African-Christian South.
Step-by-step explanation:
The fighting in Sudan is largely the result of ethnic and religious identity conflicts. The African Transition Zone cuts through the center of Sudan and has created a divide between an Arab, Muslim North and an African-Christian South.
This division has been intensified by the lasting impacts of colonialism, which politically joined these distinct regions, leading to prolonged civil wars and immense suffering for the people of Sudan, millions of whom have died or become refugees.
Although factors like access to oil deposits and quests for political and military power have played roles, the deepest roots of the conflict lie in the sharp ethnic and religious differences between the North and South.
