The Abyei Area (Arabic: أبيي) is an area of 10,546 square kilometres (2,606,000 acres) (4,072 sq mi) in Sudan accorded "special administrative status" by the 2004 Protocol on the Resolution of the Abyei Conflict (Abyei Protocol) in the Comprehensive Peace Agreement (CPA) that ended the Second Sudanese Civil War. The capital of Abyei Area is Abyei Town. The area is claimed by South Sudan but currently controlled by the northern Sudanese government.
Considered a historical bridge between northern and southern Sudan, the Abyei Area had previously been considered part of the larger Abyei District within the now-abolished state of West Kordofan. Under the terms of the Abyei Protocol, the Abyei Area was declared, on an interim basis, to be simultaneously part of the states of South Kordofan and Northern Bahr el Ghazal.
In contrast to the borders of the former district, the Abyei Protocol defined the Abyei Area as "the area of the nine Ngok Dinka chiefdoms transferred to Kordofan in 1905". In 2005, a multinational border commission established this to be those portions of Kordofan south of 10°22′30″ N. However, following continued disputes that erupted into violence and threatened the CPA, an international arbitration process redrew Abyei's boundaries in 2009 to make it significantly smaller, extending no further north than 10°10′00" N. This revised border has now been endorsed by all parties to the dispute.
