1960 Ethiopian coup attempt

The 1960 Ethiopian coup d'etat attempt (Amharic: የታህሳሱ ግርግር) was perpetrated against Emperor Haile Selassie on 13 December 1960. The Council of the Revolution, four conspirators led by brothers Germame Neway and Brigadier General Mengistu Neway, commander of the Kebur Zabagna (Imperial Bodyguard), sought to overthrow the Emperor during a state visit to Brazil in order to install a progressive government. The coup leaders declared the beginning of a new government under the rule of Haile Selassie's eldest son, Crown Prince Asfaw Wossen, that would address the numerous economic and social problems Ethiopia faced. The Council gained control of most of the capital city, Addis Ababa, and took several ministers and other important people hostage. After its initial success, the majority of the military and populace quickly aligned against the coup, and by 17 December loyalists had regained control of Addis Ababa. At least 300 people were killed during the coup, including most of the conspirators.

The coup attempt is considered the most serious threat to Haile Selassie's rule between 1941 and his deposition in 1974 during the Ethiopian Revolution.
