Opinion within Ethiopia turned against Haile Selassie owing to the worldwide 1973 oil crisis causing a sharp increase in gasoline prices starting on 13 February 1974. The high gasoline prices motivated taxi drivers and teachers to go on strike on 18 February 1974, and students and workers in Addis Ababa began demonstrating against the government on 20 February 1974. There were resulting food shortages, uncertainty regarding the succession, border wars and discontent in the middle class created through modernization. The feudal oligarchical cabinet of Akilou Habte Wolde was toppled, and a new government was formed with Endelkachew Makonnen serving as Prime Minister.
