South Sudan's independence in 2011 culminated from decades of marginalization, conflict, and a negotiated peace process.
After Sudan's 1956 independence, power remained concentrated in the Arab north. Southerners faced political exclusion, resource diversion, and cultural suppression. The 1983 imposition of Sharia law and the SPLM's Juba Declaration demanding self-determination reignited war.
The 1972 Addis Ababa Agreement collapsed. The 2005 Comprehensive Peace Agreement (CPA) finally held, granting the south autonomy and a referendum on secession.
In January 2011, 98.8% of southern voters chose independence. On July 9, 2011, the Republic of South Sudan was declared, swiftly recognized by the UN and the international community.
The separation was the result of a half-century of structural inequality, violence, and the southern people's unwavering demand for self-rule.
