The 1928 Ethiopian coup d'état was an attempt by supporters of Empress Zewditu to rid her of the heir apparent and Crown Prince, Ras Tafari Makonnen. With Tafari gone, Zewditu would be the sole ruler of the Ethiopian Empire (Mangista Ityop'p'ya). In September 1928, in Addis Ababa, a group of palace reactionaries made a final bid to rid the Empress of Tafari. The group included some of Zewditu's courtiers. The attempted coup d'état was tragic in its origins and comic in its end. In the end, the superiority of arms of the forces supporting Tafari decided the outcome in his favor.
