The 1964 Ethiopian–Somali Border War, also known as the First Ogaden War marked the first military conflict between the newly established Somali Republic and the Ethiopian Empire, lasting from February to April 1964. The border conflict was preceded by a rebellion in the Ogaden region during mid-1963 that was waged by Somalis seeking self-determination from imperial rule. Large scale Ethiopian counterinsurgency operations and increasingly harsh military crackdowns on the population of the Ogaden carried out by Emperor Haile Selassie's government resulted in a rapid decline in Ethio-Somali relations, leading to direct confrontation between both governments' armed forces.
Cuban foreign policy during the Cold War emphasized providing direct military assistance to friendly governments and resistance movements worldwide. This policy was justified directly by the Marxist concept of proletarian internationalism and was first articulated by Cuban leader Fidel Castro at the Organization of Solidarity with the People of Asia, Africa and Latin America in 1966. However, as an informal policy it had been adopted as early as 1959, shortly after the Cuban Revolution. It formed the basis for a number of Cuban military initiatives in Africa and Latin America, often carried out in direct conjunction with the Soviet Union and Warsaw Pact member states which provided advisory or logistical support. These operations were often planned by the Cuban general staff through an overseas headquarters known as an internationalist mission.
