Troops loyal to Emperor Haile Selassie in Ethiopia crush the coup that began December 13, returning power to their leader upon his return from Brazil. Haile Selassie absolves his son of any guilt.

Haile Selassie I was Emperor of Ethiopia from 1930 to 1974. He rose to power as the Regent Plenipotentiary of Ethiopia under Empress Zewditu between 1916 and 1930.

Ethiopia, officially the Federal Democratic Republic of Ethiopia, is a landlocked country located in the Horn of Africa region of East Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia covers a land area of 1,104,300 square kilometres (426,400 sq mi). As of 2024, it has around 128 million inhabitants, making it the thirteenth-most populous country in the world, the second-most populous in Africa after Nigeria, and the most populous landlocked country on Earth. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates.

The 1960 Ethiopian coup attempt was a failed coup d'état perpetrated against Emperor Haile Selassie on 13 December 1960 by the Council of the Revolution, a cabal of four conspirators led by brothers Germame Neway and Brigadier General Mengistu Neway, commander of the Kebur Zabagna, that 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.

December 13 is the 347th day of the year in the Gregorian calendar; 18 days remain until the end of the year.
