Mohamed Siad Barre (Somali: Maxamed Siyaad Barre, Arabic: محمّد زياد بري‎) (October 6, 1919 – January 2, 1995) was the military dictator and President of the Somali Democratic Republic from 1969 to 1991. During his rule, he styled himself as Jaalle Siyaad ("Comrade Siad").

At the time of independence in 1960, Somalia was touted in the West as the model of a democracy in Africa. However, clanism and extended family loyalties and conflicts were social problems the civilian government failed to eradicate and eventually succumbed to itself.

The Barre-led military junta that came to power after a coup d'état in 1969 said it would adapt scientific socialism to the needs of Somalia. It drew heavily from the traditions of China. Volunteer labour harvested and planted crops, and built roads and hospitals. Almost all industry, banks and businesses were nationalised, and cooperative farms were promoted. The government forbade clanism and stressed loyalty to the central authorities. A new writing script for the Somali language was also adopted. To spread the new language and the methods and message of the revolution, secondary schools were closed in 1974 and 25,000 students from fourteen to sixteen years of age and an additional 3,000 military and civil service employees were sent to rural areas to educate their nomadic relatives.

Idi Amin Dada (c. 1924 – 16 August 2003) was the military dictator and third President of Uganda from 1971 to 1979. Amin joined the British colonial regiment, the King's African Rifles in 1946. Eventually he held the rank of Major General in the post-colonial Ugandan Army and became its Commander before seizing power in the military coup of January 1971, deposing Milton Obote. He later promoted himself to Field Marshal while he was the head of state. While serving in the British Regiment he toured Kenya.

Amin's rule was characterised by gross human rights abuse, political repression, ethnic persecution, extrajudicial killings, nepotism, corruption, and gross economic mismanagement. The number of people killed as a result of his regime is estimated by international observers and human rights groups to range from 100,000 to 500,000. During his years in power, Amin shifted in allegiance from being a pro-Western ruler enjoying considerable Israeli support to being backed by Libya's Muammar al-Gaddafi, the Soviet Union and East Germany.
