The Second Battle of Heglig was an armed confrontation of the 2012 South Sudan-Sudan border conflict that broke out on 10 April 2012.

The First Battle of Heglig was a military campaign of South Sudan that gave rise to the 2012 South Sudan–Sudan border conflict.

The Heglig Crisis was a brief war fought between the countries of Sudan and South Sudan in 2012 over oil-rich regions between South Sudan's Unity and Sudan's South Kordofan states. South Sudan invaded and briefly occupied the small border town of Heglig before being pushed back by the Sudanese army. Small-scale clashes continued until an agreement on borders and natural resources was signed on 26 September, resolving most aspects of the conflict.

Sudanese nomadic conflicts are non-state conflicts between rival nomadic tribes taking place in the territory of Sudan and, since 2011, South Sudan. Conflict between nomadic tribes in Sudan is common, with fights breaking out over scarce resources, including grazing land, cattle and drinking water. Some of the tribes involved in these clashes have been the Messiria, Maalia, Rizeigat and Bani Hussein Arabic tribes inhabiting Darfur and West Kordofan, and the Dinka, Nuer and Murle African ethnic groups inhabiting South Sudan. Conflicts have been fueled by other major wars taking place in the same regions, in particular the Second Sudanese Civil War, the War in Darfur and the Sudanese conflict in South Kordofan and Blue Nile.
