Riek Machar is a South Sudanese politician and former rebel leader who has been a central and polarizing figure in the politics and armed conflicts of Sudan and South Sudan since the late 1970s. He has held senior posts including Deputy President and First Vice President in transitional arrangements, led multiple insurgencies and splinter movements, and participated in several peace negotiations that shaped the independence and post-independence trajectory of South Sudan. His career spans affiliations with liberation movements, regional administrations, and international mediation efforts involving neighboring states and multilateral institutions.
Born in the early 1950s in the Pibor County area of what was then Bahr el Ghazal and later Upper Nile (state), he belongs to the Nuer people ethnic group. He attended primary and secondary schooling in Juba and Khartoum before leaving Sudan to pursue higher studies in the United Kingdom, where he studied science and engineering. During his time abroad he became associated with student networks connected to the Sudan People's Liberation Movement and met figures from the Southern Sudan Liberation Movement and the broader Sudanese exile community, which influenced his subsequent return to armed struggle.
His early political alignment was with the Sudan People's Liberation Movement (SPLM) under the leadership of John Garang, with whom he served in the senior leadership of the insurgency that fought the Sudanese government during the late 20th century. After splits within the SPLM, he established or led factions such as the Sudan People's Liberation Movement/Army-Nasir and later formed political groupings that engaged with regional actors including Ethiopia, Uganda, and Kenya. He has been appointed to high offices in transitional administrations, including roles in the Government of South Sudan and in power-sharing structures established after the Comprehensive Peace Agreement and subsequent accords.
During the Second Sudanese Civil War, he rose to prominence as a senior commander and political commissar within the SPLM/A, participating in strategic decisions and campaigns across Bahr el Ghazal, Upper Nile (Sudan), and Equatoria. In the mid-1990s internal disputes culminated in a major split when he challenged the leadership of John Garang and declared a breakaway faction that aligned tactically with external actors such as the Government of Sudan in Khartoum. The split precipitated intra-South violence, involving clashes with commanders loyal to Garang, interactions with militias linked to the Sudan Armed Forces, and realignments involving leaders like Lam Akol and Gatluak Gai.
Following the Comprehensive Peace Agreement of 2005 and the 2011 South Sudanese independence referendum, he served in senior executive roles in the newly established Republic of South Sudan, including as First Vice President and later as Vice President in transitional and coalition arrangements with President Salva Kiir Mayardit. His tenure involved responsibilities for national administration, participation in cabinet decision-making, and interaction with institutions such as the South Sudanese parliament, regional governors, and international partners like the Intergovernmental Authority on Development (IGAD) and the United Nations Mission in South Sudan (UNMISS). His governance period was marked by attempts at power-sharing, economic management during oil revenue disputes with Sudan, and navigation of inter-communal tensions.
At multiple junctures he broke from the ruling administration to lead armed opposition movements, most prominently during the 2013–2018 civil conflict that erupted after political rivalries with President Salva Kiir—a dispute that aligned broadly along ethnic lines between Nuer people and Dinka people. He commanded forces under banners such as the Sudan People's Liberation Movement-in-Opposition (SPLM-IO) and formed alliances with other armed actors including commanders like Tobruk-affiliated leaders and regional militia figures. These insurgent phases involved battles across Jonglei State, Unity State, and Upper Nile, and drew responses from regional militaries and international mediators.
He has been a principal signatory and participant in multiple peace processes, negotiating accords such as the Khartoum Peace Agreement-era arrangements, the post-2005 Comprehensive Peace Agreement implementation talks, and the IGAD-mediated agreements that culminated in the 2015 Agreement on the Resolution of the Conflict in the Republic of South Sudan and the 2018 Revitalised Agreement on the Resolution of the Conflict in the Republic of South Sudan (R-ARCSS). These negotiations involved parties like the Government of Sudan, the African Union Commission, representatives of the Troika (United States, United Kingdom, Norway), and envoys such as Salva Kiir counterparts and international figures including mediators from Ethiopia and Kenya. Implementation of accords has been uneven, involving ceasefires, cantonment of forces, and formation of transitional institutions monitored by the United Nations and regional guarantors.
His personal life intersects with political controversy: accusations of human rights abuses, alleged involvement in ethnic violence, and disputes over resource control and patronage networks have been raised by organizations such as Human Rights Watch and by UN human rights investigators. Domestic critics and international observers have pointed to episodes of alleged breaches of ceasefire accords, contested leadership legitimacy within the SPLM-IO, and controversies surrounding corruption and governance during his terms in office. He has familial ties into South Sudanese elite circles and has been subject to sanctions and diplomatic pressures at various times from actors including the United States Department of State and international partners pressing for accountability and implementation of peace agreements.
