United Somali Congress in the context of Mohamed Farrah Aidid

The Somali Civil War (Somali: Dagaalkii Sokeeye ee Soomaaliya; Arabic: الحرب الأهلية الصومالية al-ḥarb al-’ahliyya aṣ-ṣūmāliyya) is an ongoing civil war that is taking place in Somalia. It grew out of resistance to the military junta which was led by Siad Barre during the 1980s. From 1988 to 1990, the Somali Armed Forces began engaging in combat against various armed rebel groups, including the Somali Salvation Democratic Front in the northeast, the Somali National Movement in the Somaliland War of Independence in the northwest, and the United Somali Congress in the south. The clan-based armed opposition groups overthrew the Barre government in 1991.

Various armed factions began competing for influence in the power vacuum and turmoil that followed, particularly in the south. In 1990–92, customary law temporarily collapsed, and factional fighting proliferated. In the absence of a central government, Somalia became a "failed state". This precipitated the arrival of UNOSOM I UN military observers in July 1992, followed by the larger UNITAF and UNOSOM II missions. Following an armed conflict between Somali insurgents and UNOSOM II troops during 1993, the UN withdrew from Somalia in 1995. After the central government's collapse and the withdrawal of UN forces, there was some return to customary and religious law in most regions. In 1991 and 1998, two autonomous regional governments were also established in the northern part of the country: Somaliland and Puntland. In the south Islamic Sharia courts began proliferating in response to lawlessness. This led to a relative decrease in the intensity of the fighting, with the Stockholm International Peace Research Institute removing Somalia from its list of major armed conflicts for 1997 and 1998.

Ali Mahdi Muhammad (Somali: Cali Mahdi Maxamed, Arabic: علي مهدي محمد) (1 January 1939 – 10 March 2021) was a Somali entrepreneur and politician. He served as President of Somalia from 26 January 1991 to 27 August 2000. The Cairo Agreement in December 1997 designated Ali Mahdi as president once again, a position he held until being succeeded by Abdiqasim Salad in the year 2000.

Muhammad rose to power after a coalition of armed opposition groups, including his own United Somali Congress, deposed longtime dictator Siad Barre. However, Muhammad was not able to exert his authority beyond parts of the capital, and instead vied for power with other faction leaders in the southern half of the country and with autonomous subnational entities in the north.

The Somali National Alliance (abbreviated SNA) was a major politico-military faction formed on 16 June 1992 by four different rebel groups that had been in opposition to the regime of former President Mohamed Siad Barre. The SNA was the first major inter-clan and inter-factional political alliance and was considered to be among the most powerful factions of the Somali Civil War. The alliance most notably faced off against the second phase of the United Nations Operation in Somalia (UNOSOM II) during the insurgency that emerged against foreign troops in the latter half of 1993.

Following the 1991 split in the United Somali Congress (USC) between Mohamed Farah Aidid and his primary rival Ali Mahdi Muhammad and the routing of Barre's forces out of Somalia and into Kenya during 1992, a tentative military coalition that had existed between different rebel organizations morphed into the politico-military organization known as the SNA. The alliance included Aidid's breakaway wing of the USC, the Somali Patriotic Movement (SPM), the Somali Southern National Movement (SSNM) and Somali Democratic Movement (SDM). The organization professed the goal of working toward forming a national reconciliation government and an eventual multi-party democracy.
