The Sudanese Civil War culminated in an agreement to allow the southern part of the country to succeed if the proposition passed a popular referendum. This was a compromise between the Sudan People's Liberation Movement of the south and the National Congress Party of the north to take a step forward from the 2005 Comprehensive Peace Agreement that ended decades of civil strife. The requirements for succession were set at a 51% south Sudanese vote in favor of the motion predicated on at least a 60% voter turnout. Referendum rules were set to deal with the prospect of the oil-rich Abyei region, though dispute over the territory persists today.
The vote resulted in a 98.83% yes vote and Sudanese President Omar al-Bashir officially accepted the outcome. On July 9, 2011, South Sudan was officially welcomed into the community of nations. Salva Kir led the Sudan People's Liberation Movement, and he was sworn in as the nascent nation's first president. Kiir is currently serving a four-year term.
