Some areas still posthumously entitled by members of various nobilities of that time: such as Dejazemach Wube Haile Mariam, Fitawrari Aba Koran, and a bridge named "Fitawrari Habtegiorgis" after Habte Giyorgis Dinagde. According to 1965 master plan, the city covered the area of 21,000 hectares and would increased to 51,000 hectares by 1984 master plan. The city had only 10 woredas. The Haile Selassie regime faced backlash—as evident of 1960 coup d'etat attempt—from various reactionary partisans. In 1965, Haile Selassie I University, later Addis Ababa University students marched chanting "Land to the Tiller" as a response of the imperial feudal system, culminating in series revolutionary protests across Addis Ababa, and ushering Marxist–Leninist momentum.
