President of Somalia in the context of "List of Presidents of Somalia"

Mohammed Siad Barre (Somali: Maxamed Siyaad Barre; Arabic: محمد زياد بري, romanized: Muhammad Ziād Barīy; c. 6 October 1919 – 2 January 1995) was a Somali military officer, politician, and revolutionary who served as the third president of Somalia from 21 October 1969 to 26 January 1991.

Barre, the commander of the Somali National Army, became president of Somalia after the 1969 coup d'état that overthrew the Somali Republic following the assassination of President Abdirashid Shermarke. The Supreme Revolutionary Council military junta under Barre reconstituted Somalia as a one-party Marxist–Leninist communist state, renamed the country the Somali Democratic Republic and adopted scientific socialism. Barre spoke three languages, English, Somali and Italian.

The Somali Armed Forces are the military forces of the Federal Republic of Somalia. Headed by the president as commander-in-chief, they are constitutionally mandated to ensure the nation's sovereignty, independence and territorial integrity.

In 1990 the Armed Forces were made up of the Army, Air Force, Air Defence Force, and Navy. From the early 1960s to 1977, the periodwhen good relations existed between Somalia and the Soviet Union, the Armed Forces had the largest armored and mechanized force in sub-Saharan Africa. Due to Barre's increasing reliance on his own clan, splitting the Armed Forces along clan lines, and the Somali Rebellion, by 1988 they began to disintegrate. By the time President Siad Barre fled Mogadishu in January 1991, the last cohesive army grouping, the 'Red Berets,' had deteriorated into a clan militia.

Abdirashid Ali Sharmarke (Somali: Cabdirashiid Cali Sharmaarke, Arabic: عبد الرشيد علي شرماركي) (8 June 1919 – 15 October 1969), was the first Prime Minister of the Somali Republic from 12 July 1960 to 14 June 1964 and the second President from 6 July 1967, until his assassination on October 15, 1969.

Abdullahi Yusuf Ahmed (Somali: Cabdulaahi Yuusuf Axmed, Arabic: عبدالله يوسف أحمد‎; 15 December 1934 – 23 March 2012), was a Somali politician and former military official who served as the first President of Puntland from 1998 to 2004. He also played a key role in establishing the Transitional Federal Government (TFG), which he led as President of Somalia from 2004 to 2008. Additionally, he was one of the founders of the rebel Somali Salvation Democratic Front (SSDF).

Yusuf was a career soldier in the Somali National Army, participating in the 1964 Border War and Ogaden War against Ethiopia. After Somalia's defeat in the Ogaden War in 1978, he led a failed coup against President Siad Barre, marking the start of the Somali rebellion. Following the coup's failure, Yusuf established the Somali Salvation Democratic Front in Ethiopia and began fighting alongside Ethiopian forces against the Somali army. During the 1982 Ethiopian-Somali War, he led SSDF forces. Frustrated by the operation's failure and the SSDF's surrender to the Somali government, the Ethiopians jailed Yusuf until the Derg regime collapsed in 1991.
