On 9 July 2011, the Republic of South Sudan formally dissolved its union with Sudan, becoming the world's newest recognised state. The secession followed a 2005 peace agreement and a 2011 referendum in which 98.83% voted for independence.
The dissolution was, by the standards of such things, orderly. A new capital rose in Juba. Ministries were formed. Ambassadors were exchanged.
Within two years, civil war had begun.
The dissolution of a state, it turns out, does not end the forces that demanded it. The same centrifugal logic that split Sudan into two continued to operate on the smaller pieces. By 2025, South Sudan had experienced multiple internal fractures, a famine declared in parts of Unity State, and a peace process that had collapsed and reformed so many times that counting became a genre of its own.

In Fiction
Chinua Achebe's Anthills of the Savannah (1987) depicts a fictional West African state dissolving under military rule. The novel is less about secession than about the dissolution of civil society — the slow erosion of trust, language, and memory under authoritarian pressure. The state does not split; it crumbles from within.
