referendum took place in Southern Sudan from 9 to 15 January 2011, on whether the region should remain a part of Sudan or become independent. The referendum was one of the consequences of the 2005 Naivasha Agreement between the Khartoum central government and the Sudan People's Liberation Army/Movement (SPLA/M).
A simultaneous referendum was supposed to be held in Abyei on whether to become part of Southern Sudan but it was postponed due to conflict over demarcation and residency rights.
On 7 February 2011, the referendum commission published the final results, with 98.83% voting in favor of independence. While the ballots were suspended in 10 of the 79 counties for exceeding 100% of the voter turnout, the number of votes was still well over the requirement of 60% turnout, and the majority vote for secession is not in question.
The predetermined date for the creation of an independent state was 9 July 2011.
