Comprehensive Peace Agreement in the context of "South Sudanese independence referendum, 2011"

South Sudan (/suːˈdɑːn, -ˈdæn/), officially the Republic of South Sudan, is a landlocked country in East Africa. It is bordered by Sudan to the north, Ethiopia to the east, the Democratic Republic of the Congo to the southwest, Uganda to the south, Kenya to the southeast and to the west by the Central African Republic. South Sudan's diverse landscape includes vast plains and plateaus, dry and tropical savannahs, inland floodplains, and forested mountains. The Nile River system is the defining physical feature of the country, running south to north across its center, which is dominated by a large swamp known as the Sudd. South Sudan has an estimated population of just over 12.7 million in 2024. Juba is the capital and largest city.

Sudan was occupied by Egypt under the Muhammad Ali dynasty and governed as an Anglo-Egyptian condominium until Sudanese independence in 1956. Following the First Sudanese Civil War, the Southern Sudan Autonomous Region was formed in 1972 and lasted until 1983. A second Sudanese civil war soon broke out in 1983 and ended in 2005 with the Comprehensive Peace Agreement. Later that year, southern autonomy was restored when an Autonomous Government of Southern Sudan was formed. South Sudan became an independent state on 9 July 2011, following 98.8% support for independence in a January 2011 referendum. It is the most recent sovereign state with widespread recognition as of 2025. South Sudan descended into a civil war from 2013 to 2020, enduring rampant human rights abuses, including forced displacement, ethnic massacres, and killings of journalists by various parties. It has since been governed by a coalition formed by leaders of the former warring factions, Salva Kiir Mayardit (Sudan People's Liberation Movement or SPLM) and Riek Machar (Sudan People's Liberation Movement-in-Opposition or SPLM-IO). The country continues to recover from the war while experiencing ongoing and systemic ethnic violence.

Juba is the capital and largest city of South Sudan. The city is situated on the White Nile and also serves as the capital of the Central Equatoria State. It is the most recently declared national capital and had a population of 525,953 in 2017. It has an area of 52 km (20 sq mi), with the metropolitan area covering 336 km (130 sq mi).

Juba was established in 1920–21 by the Church Missionary Society (CMS) in a small Bari village, also called Juba. The city was made as the capital of Mongalla Province in the late 1920s. The growth of the town accelerated following the signing of the Comprehensive Peace Agreement in 2005, which made Juba the capital of the Autonomous Government of Southern Sudan. Juba became the capital of South Sudan in 2011 after its independence, but influential parties wanted Ramciel to be the capital. The government announced the move of the capital to Ramciel, but it is yet to occur.

Southern Sudan (Arabic: حكومة جنوب السودان Ḥukūmat Janūb as-Sūdān; Dinka: Lɔ̈k Bïkrotmac Paguot Thudän) was an autonomous region consisting of the ten southern states of Sudan between its formation in July 2005 and independence as the Republic of South Sudan in July 2011. The autonomous government was initially established in Rumbek and later moved to Juba. It was bordered by Ethiopia to the east; Kenya, Uganda, and the Democratic Republic of the Congo to the south; and the Central African Republic to the west. To the north lies the predominantly Arab and Muslim region directly under the control of the central government. The region's autonomous status was a condition of a peace agreement between the Sudan People's Liberation Army/Movement (SPLA/M) and the Government of Sudan represented by the National Congress Party ending the Second Sudanese Civil War. The conflict was Africa's longest running civil war.

Salva Kiir Mayardit (born 13 September 1951), commonly known as Salva Kiir, is a South Sudanese politician who has served as the President of South Sudan since its independence on 9 July 2011. Prior to independence, he was the President of the Government of Southern Sudan, as well as First Vice President of Sudan, from 2005 to 2011. He was named Commander-in-Chief of the Sudan People's Liberation Army (SPLA) in 2005, following the death of John Garang.

Kiir was born to the Dinka ethnic group and joined Anyanya rebels fighting for Southern independence during the First Sudanese Civil War in 1967. Following the outbreak of the Second Sudanese Civil War in 1983, Kiir joined the new Sudan People's Liberation Movement (SPLM) rebel group led by John Garang as a member of its armed wing, the Sudanese People's Liberation Army (SPLA), eventually becoming the head of the SPLA. Following the Comprehensive Peace Agreement, the South gained autonomy under the leadership of Garang in July 2005. Following Garang's death at the end of the month, Kiir became the new President of the Southern Autonomous region, as well as First Vice President of the central government. Kiir won re-election as President following the 2010 South Sudanese general election. The following year, South Sudan gained independence after the 2011 South Sudanese independence referendum with Kiir as its inaugural President.

The Sudan People's Liberation Movement (SPLM; Arabic: الحركة الشعبية لتحرير السودان, Al-Ḥarakat ash-Shaʿbiyyat liTaḥrīr as-Sūdān) is a political party in South Sudan. It was initially founded as the political wing of the Sudan People's Liberation Army (SPLA; a key belligerent of the Second Sudanese Civil War) 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.

Although the party has not adhered to one consistent ideology since the independence of South Sudan and many factions exist, it has been described as "being on the left of centre ideological[ly] speaking," and section IV.2 of the party manifesto states support for a regulated market economy with similar elements to social democracy.

Kordofan (Arabic: كردفان Kurdufān) is a former province of central Sudan. In 1994 it was divided into three new federal states: North Kordofan, South Kordofan and West Kordofan. In August 2005, West Kordofan State was abolished and its territory divided between North and South Kordofan States, as part of the implementation of the Comprehensive Peace Agreement between the Government of Sudan and the Sudan People's Liberation Movement. West Kordofan was reestablished in July 2013.
