The Sudan People's Liberation Movement and the Government of Sudan sign the Comprehensive Peace Agreement to end the Second Sudanese Civil War.

The Sudan People's Liberation Movement is a political party in South Sudan. It was initially founded as the political wing of the Sudan People's Liberation Army in 1983. On January 9, 2005 the SPLA, the SPLM and the Government of Sudan signed the Comprehensive Peace Agreement, ending the civil war. SPLM then obtained representation in the Government of Sudan, and was the main constituent of the Government of the then semi-autonomous Southern Sudan. When South Sudan became a sovereign state on 9 July 2011, SPLM became the ruling party of the new republic. SPLM branches in Sudan separated themselves from SPLM, forming the Sudan People's Liberation Movement–North. Further factionalism appeared as a result of the 2013–2014 South Sudanese Civil War, with President Salva Kiir leading the SPLM-Juba and former Vice President Riek Machar leading the Sudan People's Liberation Movement-in-Opposition.

The Government of Sudan is the federal provisional government created by the Constitution of Sudan having executive, parliamentary, and the judicial branches. Previously, a president was head of state, head of government, and commander-in-chief of the Sudanese Armed Forces in a de jure multi-party system. Legislative power was officially vested in both the government and in the two houses – the National Assembly (lower) and the Council of States (upper) – of the bicameral National Legislature. The judiciary is independent and obtained by the Constitutional Court. However, following the Second Sudanese Civil War and the still ongoing genocide in Darfur, Sudan was widely recognized as a totalitarian state where all effective political power was held by President Omar al-Bashir and his National Congress Party (NCP). However, al-Bashir and the NCP were ousted in a military coup on April 11, 2019. The government of Sudan was then led by the Transitional Military Council (TMC). On 20 August 2019, the TMC dissolved giving its authority over to the Transitional Sovereignty Council, who were planned to govern for 39 months until 2022, in the process of transitioning to democracy. However, the Sovereignty Council and the Sudanese government were dissolved in October 2021.
