UNMIS wound up its operations on 9 July 2011 with the completion of the interim period agreed on by the Government of Sudan and Sudan People’s Liberation Movement in the Comprehensive Peace Agreement (CPA), signed on 9 January 2005.
The mission ended its six years of mandated operations the same day South Sudan declared independence, following a CPA-provided referendum on 9 January 2011 that voted overwhelmingly in favour of secession.
In support of the new nation, the Security Council established a successor mission to UNMIS – the UN Mission in South Sudan (UNMISS) – on 9 July for an initial period of one year, with the intention to renew for further periods as required.
