Historical Trajectory
Phase I: Rise
In October 1969, Major General Siad Barre led a military coup following the assassination of President Abdirashid Ali Shermarke, dissolving the civilian government and establishing the Supreme Revolutionary Council. Barre proclaimed Somalia a socialist state, nationalised key industries, and aligned the country with the Soviet Union, consolidating power under the newly formed Somali Revolutionary Socialist Party.
Phase II: Zenith
During the 1970s, the Barre government pursued ambitious modernisation programmes, most notably the standardisation and official adoption of a written Somali script in 1972, enabling mass literacy campaigns. Infrastructural investment and state-led development projects expanded across the country, and Somalia maintained significant Soviet military and economic support until shifting alignment toward the United States after the Ogaden War.
Phase III: Decline
The costly Ogaden War against Ethiopia (1977–1978) drained military resources and triggered a loss of Soviet backing. Economic deterioration, clan-based insurgencies, and widespread human rights abuses eroded Barre's authority through the 1980s. By 1991, armed opposition factions overran Mogadishu, forcing Barre into exile and dissolving central government authority, plunging Somalia into prolonged civil war and state collapse.
