Collapse, 1991–2000

Timeline

• Jan 1991. USC-led uprising overthrows Barre, who flees to Gedo in the south-west; USC forms an interim government (Ali Mahdi Mahammad, interim president) that other fronts reject. Actors: USC; SNM; SPM; SSDF What it meant for unity: No inclusive successor authority; the state's collapse begins Source: S22; S20
• May–Jun 1991. SNM declares the Republic of Somaliland in former British Somaliland, calling the 1960 union "null and void" and rejecting the USC government (Britannica: May; LoC: June).

• Summer–Sep 1991. USC splits: the forces of Ali Mahdi and of Gen. Aidid fight in Mogadishu, after a dispute over posts; by end of 1991 the city is divided (Aidid ~10,000 fighters, Ali Mahdi ~5,000).

• Nov 1991 – early 1992. A UN aid doctor is killed in Bender Cassim, reportedly by an underground Islamist movement; LoC describes "messianic Islamism" filling the gap left by state collapse. Actors: Unnamed Islamist cell What it meant for unity: Islamism emerges as an alternative order Source: S18
• 1992. Drought and famine in the south; armed groups loot an estimated 80% of food shipments; both Mogadishu sides use food as a weapon; UN-mediated ceasefire (Mar 1992). Actors: Faction militias; UN What it meant for unity: Fragmentation turns into mass death Source: S20; S19

What the record shows

• Armed fronts did not turn into a national government. LoC notes that the USC "did not adapt well" from guerrilla force to party and split between Ali Mahdi and Aidid (S19).
• Two answers to collapse: separation and autonomy within Somalia. Somaliland repudiated the union; Puntland declared autonomy within Somalia (S22). The killings of 1988 in the north remain the founding grievance in Somaliland (S16).
• Outside military intervention did not rebuild the state (UNITAF/UNOSOM, 1992–95) (S22).
