When the Dinka arrived in the region of Bahr el Ghazal, they found it inhabited by the Nuer.

The Nuer, who were nomadic, were not pleased with the arrival of the Dinka, who were pastoralists.

A conflict arose between the two tribes over land and water.

The Dinka, who were more numerous and better armed, eventually drove the Nuer out of the region.

The Nuer, however, did not give up easily. They continued to raid the Dinka settlements, and the conflict continued for many years.

The Dyo, who were a smaller tribe, were caught in the middle of the conflict. They were forced to choose sides, and many of them were killed.

The Dinka eventually emerged victorious, and they established their dominance over the region.

The Nuer, however, were not completely defeated. They continued to resist the Dinka, and the conflict continued for many years.

The Dinka and Nuer conflict had a profound impact on the history of Sudan. It led to the displacement of many people, and it contributed to the fragmentation of the region.

The conflict also had a lasting impact on the relationship between the Dinka and Nuer tribes. The two tribes have a long history of animosity, and the conflict has only served to deepen that animosity.
