Abyei territory claimed by South Sudan
The Abyei Area (Arabic: منطقة أبيي) is an area of 10,546 km2 or 4,072 sq mi on the border between South Sudan and the Sudan that has been 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 the Abyei Area is Abyei Town. Under the terms of the Abyei Protocol, the Abyei Area is considered, on an interim basis, to be simultaneously part of both the Republic of South Sudan and the Republic of the Sudan, effectively a condominium.
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.
