South Sudan

South Sudan entered 2025 in a deepening political and security crisis that by March had escalated to the brink of full-scale civil war. The proximate trigger was a clash on 3 March 2025 in Nasir, a town in Upper Nile State near the Ethiopian border, where fighters from the Nuer White Army overran a South Sudan People's Defence Forces (SSPDF) military base. During an attempted evacuation of SSPDF troops, a UN helicopter came under fire, and 27 soldiers died. The government responded with military operations — including airstrikes — against civilian-populated areas across Upper Nile State. The UN reported in April 2025 that the government used improvised incendiary weapons in at least four attacks, killing at least 58 people. An estimated 63,000 people were displaced in the immediate aftermath; by early 2026 internal displacement had risen by 40% to 3.2 million.

The political response was equally dramatic. President Salva Kiir — who accused opposition-affiliated forces of organizing the attack — placed First Vice President Riek Machar under house arrest in March 2025, surrounding his compound with government troops. In September 2025, Machar, along with seven co-defendants, was formally charged with murder, treason, and crimes against humanity. His trial began on 22 September 2025 and is ongoing as of early 2026. The charges are widely seen as politically motivated — a Small Arms Survey report found that "Riek Machar and the leadership of the SPLM/A-IO were not responsible for the March 2025 assault on the SSPDF barracks in Nasir." Machar's detention effectively suspended the 2018 Revitalized Agreement on the Resolution of the Conflict (R-ARCSS) — the power-sharing deal that was supposed to lead to elections in December 2026. Those elections are now in serious doubt.

Fighting has expanded beyond Upper Nile State. Clashes between government forces and opposition elements have been reported in Jonglei, Unity, Western Equatoria, and Western Bahr el-Ghazal states. Uganda deployed special forces to South Sudan in support of Kiir's government, which both the opposition and international observers noted as a potential violation of the UN arms embargo. Between March 2025 and January 2026, the UN verified 5,519 deaths from conflict-related violence. The UN says South Sudan "shows all the signs of a clear and present danger of relapsing back to full-scale conflict."

The humanitarian situation, already one of the world's worst before March 2025, has severely deteriorated. The Sudan civil war to the north continues to drive refugees into South Sudan; South Sudan's main oil export pipeline — its primary revenue source — ruptured in 2024 due to the Sudan conflict and remains non-operational, creating a deep fiscal crisis that has further destabilized Kiir's capacity to maintain political alliances. The combination of active conflict, oil revenue collapse, continuing Sudan war spillover, climate-related flooding, and a humanitarian funding shortfall (the 2025 response plan was only 28.5% funded) makes South Sudan's situation one of the most acute in the world.

The territory that became South Sudan has been contested, colonized, and fought over for centuries — but the modern conflict begins with the colonial partition of Sudan. When Britain took control of Sudan (jointly with Egypt under the Condominium of 1899), it administered the predominantly Arab and Muslim north and the predominantly Black African and Christian/animist south as effectively separate territories, discouraging north-south contact and permitting Christian missionary activity only in the south. This separation was not benevolent: it was designed to prevent the spread of Arab nationalism, and it reinforced the social and economic gulf between the wealthy, Arabic-speaking northern elite and the poorer, largely pastoralist southern population.

At the 1947 Juba Conference, Britain and northern Sudanese representatives decided — without meaningful southern consent — that an independent Sudan would unite north and south as a single country. Southerners who wanted separation were overruled. This foundational betrayal shaped everything that followed. Even before formal independence in 1956, southern soldiers mutinied in August 1955, anticipating exclusion from the post-colonial government. The First Sudanese Civil War (1955–1972) pitted the southern Anya-Nya movement against the Khartoum government. A peace deal in 1972 ended the fighting but did not address its causes, and when Khartoum imposed Islamic sharia law on the entire country in 1983 and reneged on southern autonomy commitments, the Second Sudanese Civil War began.

The Second Civil War (1983–2005) is the crucible from which both South Sudan's independence and its subsequent dysfunction emerged. The Sudan People's Liberation Army (SPLA), led by John Garang, fought for over two decades in one of Africa's bloodiest conflicts — approximately 2 million people died, and 4 million were displaced. The war involved systematic atrocity: aerial bombardment of civilian areas, deliberate starvation, slavery (Khartoum-backed northern militias raided southern communities and enslaved captured women and children), and the abduction of child soldiers. The international community paid limited attention to this catastrophe through the 1980s and 1990s.

The war finally ended with the Comprehensive Peace Agreement (CPA) of January 2005, brokered with significant US involvement under the Bush administration. The CPA provided for a six-year interim period, after which a referendum would allow southerners to vote on independence. John Garang — the SPLA's charismatic leader and the most credible figure to lead an independent South Sudan — died in a helicopter crash just three weeks after the CPA was signed, in July 2005. His successor was Salva Kiir, a Dinka from the Warrap region, less educated, less internationally connected, more dependent on the patronage networks that Garang had always kept imperfectly controlled.

The independence referendum took place in January 2011. The result was extraordinary: 98.83% voted for independence — the most overwhelming democratic mandate in the history of African elections. People queued for hours in the heat to vote. There were celebrations in the streets of Juba, in churches, in diaspora communities in Nairobi, London, Minneapolis, and Sydney. South Sudan became independent on 9 July 2011, the 54th country in Africa and the 193rd member of the United Nations. The international community celebrated. Aid money flowed. Oil revenues provided a budget. There was, briefly and genuinely, hope.

The civil war in South Sudan is often described as an ethnic conflict between the Dinka (Kiir's group, South Sudan's largest) and the Nuer (Machar's group, the second largest). This framing captures a real dimension — the massacres that began in December 2013, when Dinka presidential guards killed Nuer in Juba, and the Nuer White Army's retaliation, were nakedly ethnic in character. But ethnicity is a mechanism rather than a cause. The Council on Foreign Relations expert Alex de Waal, among others, has argued that the conflict's root was not ethnic division but the failure to build a professional, institutionalized army — instead, South Sudan had "a collection of militias, each organized on an ethnic basis," which meant that when elite political competition turned violent, it instantly became ethnic violence.

What that elite competition was actually about, at its core, was oil. South Sudan sits on approximately 3.5 billion barrels of proven oil reserves — the third-largest in sub-Saharan Africa — and oil revenue constituted 98% of government revenue in 2013, the year the civil war began. The state had essentially one source of income, and whoever controlled the state controlled that income. Kiir's "big tent" policy — keeping potential rivals onside by distributing oil money through patronage — worked while oil revenues were high. When they declined (South Sudan's oil must be exported through Sudan's pipeline, which Sudan periodically shuts), the patronage system could no longer pay off all the competing factions, political competition intensified, and conflict followed.

The result was a war in which military commanders, politicians, and local militia leaders were simultaneously ideological rivals, ethnic mobilizers, and economic competitors — fighting over cattle, mining, timber, and government contracts as much as over political power. The USHMM (United States Holocaust Memorial Museum) documented ethnic massacres and the use of rape, starvation, and torture as weapons of war. The UN warned of genocide risk in 2017. An estimated 400,000 people died between 2013 and 2018.

The 2018 Revitalized Peace Agreement created a unity government — Kiir as president, Machar as first vice president — but implementing its terms required the government to take concrete steps that reduced Kiir's power: integrating rebel and government forces into a unified army, conducting security sector reform, holding elections. None of this happened adequately. As one ruling party official told the New Humanitarian: "In many ways, the agreement froze the conflict rather than resolving it." The 2025 escalation is the frozen conflict resuming.

The broader regional context matters: the Sudan civil war (ongoing since April 2023) has pushed refugees into South Sudan, disrupted the oil pipeline, and destabilized the border. South Sudan's fiscal crisis — driven by the pipeline rupture — has weakened Kiir's ability to buy loyalty and maintain alliances, making the political situation more fragile. Several analysts warn that the South Sudan conflict could merge with the Sudan conflict, creating an unprecedented regional catastrophe.

South Sudan has approximately 60–70 ethnic groups, each with distinct languages, traditions, and territorial histories. The Dinka and Nuer are the two largest (together making up roughly 40% of the population), but the Shilluk, Azande, Bari, Kakwa, Kuku, Murle, Mundari, and dozens of other groups each have their own claims on the land, their own governance traditions, and their own relationships with the pastoral and agricultural economies of the country.

South Sudan is a landlocked country of approximately 644,000 square kilometers — larger than France. Its terrain ranges from the flat, seasonally flooded plains of the Sudd (the world's second-largest tropical wetland) to the wooded savannahs of the south and the mountains of the Eastern Equatoria highlands near the Ugandan and Kenyan borders. The country contains extraordinary wildlife that in stable conditions would support East Africa-caliber safari tourism: Boma National Park and the surrounding Boma-Jonglei landscape contain the second-largest wildlife migration on earth, with millions of white-eared kob, tiang, and Mongalla gazelle moving seasonally across the plains — a phenomenon that, unlike the Serengeti migration, almost no international visitor has ever seen.

This section is for aid workers, journalists, development professionals, diplomats, and others who have non-negotiable professional reasons to be in South Sudan. It is not a recommendation to travel. Under current conditions (early 2026), South Sudan is not safe for any category of tourist travel and is barely safe for the professional staff of international organizations who operate there with security infrastructure that individual travelers cannot access.

Emergency services in South Sudan are extremely limited to nonexistent outside Juba, and even within Juba are unreliable. The US government has limited ability to provide consular services; other Western governments have even less. If you are in South Sudan, your first call in an emergency should be to your organization's security team, then to the nearest UNMISS outpost, then to your embassy. Your embassy's ability to physically assist you may be extremely limited given current conditions.
