It borders South Darfur to the north, Western Bahr el Ghazal to the west and south, and Warrap and Abyei to the east. Aweil is the capital of the state. Because of its proximity to Kordofan and the presence of a railway line through it to Wau, it suffered extensively in the 1983–2005 civil war in southern Sudan. North Bahr al Ghazal and adjacent parts of Western Kordofan to the north were among the most politically sensitive regions in Sudan. Missriya Arabs from Kordofan have interacted with Dinka in this region over a long time. While relations during the colonial era were largely peaceful, the war saw an upsurge in hostilities. Government backing to the Missriya gave them a decided advantage over local Dinka groups, and raiding by "murahileen" militias (and other government backed groups, including some Dinka militias) resulted in considerable loss of life, widespread abduction and pillaging of Dinka villages. Many of these raids coincided with the movement of government trains to and from Kordofan to Wau. It had the highest rate of poverty, 76% according to government statistics, of the 10 states of South Sudan. Retired Gen. Salva Chol Ayat was the last Acting governor of the state. He replaced Kuel Aguer Kuel in April 2015. Northern Bahr al Ghazal, like other states in South Sudan, is divided into counties; there are five counties, headed by a County Commissioner, as detailed below:  The counties are further divided into "Payams", then "Bomas".
