Following the demise of imperial rule, the feudal socioeconomic structure was dismantled through a series of reforms which also affected educational development. By early 1975, the government had closed Haile Selassie I University and all senior secondary schools, then deployed the approximately 60,000 students and teachers to rural areas to promote the government's "Development Through Cooperation Campaign". The campaign's purposes were to promote land reform and improve agricultural production, health, and local administration and to teach peasants about the new political and social order.
