Somali National Army officers led by Major General Mohamed Siad Barre seized power in a bloodless coup in Mogadishu, suspended the constitution, dissolved key institutions, and installed the Supreme Revolutionary Council (SRC) as the ruling authority.
Roughly a year after the coup, the Barre regime publicly declared Somalia a socialist state, initiating a program of “scientific socialism” and state-led political reorganization under the SRC.
The government adopted a standardized Latin alphabet for Somali, enabling mass publication and administration in Somali and laying the groundwork for nationwide literacy drives.
Somalia was admitted to the Arab League, reflecting Barre’s effort to deepen ties with Arab states alongside Somalia’s African and Cold War alignments.
The regime created the Somali Revolutionary Socialist Party (SRSP) as the state’s ruling party, formalizing a one-party framework intended to institutionalize “scientific socialism” beyond direct military rule.
Somalia launched a major conventional offensive into Ethiopia’s Ogaden region, escalating a long-standing territorial dispute into a large interstate war that would reshape Somalia’s alliances and internal stability.
Amid the Ogaden War and Soviet backing for Ethiopia, Somalia renounced its friendship treaty with the Soviet Union and expelled Soviet military advisers, marking a dramatic pivot in Cold War alignment.
After the failed 1978 coup, dissident officers regrouped abroad and established the Somali Salvation Democratic Front (SSDF), widely described as the first major armed opposition front seeking to remove Barre.
A faction of officers attempted to overthrow Barre; the coup failed and was followed by executions and intensified security measures. The aftermath helped catalyze organized armed opposition to the regime.
Somalia adopted a new constitution via referendum, formalizing a presidential system and entrenching a one-party state structure associated with the SRSP era.
Somali exiles and dissidents founded the Somali National Movement (SNM), which became a central armed-political challenger to Barre’s rule in the north during the 1980s.
The SNM launched a major offensive, rapidly taking Burao and entering Hargeisa; government countermeasures and subsequent fighting escalated the northern war and deepened civilian displacement.
Opponents of the Barre regime formed the United Somali Congress (USC), which later became a leading force in the final assault on Mogadishu and the regime’s collapse.
After weeks of intense fighting in the capital, Barre fled Mogadishu as USC forces took key sites, effectively ending the central authority of his government and accelerating state collapse.
