The Battle of Segale was a civil conflict in the Ethiopian Empire between the supporters of Empress regent Zewditu and Lij Iyasu on 27 October 1916, and resulted in victory for Zewditu. Paul B. Henze states that "Segale was Ethiopia's greatest battle since Adwa" (1896). Background The nobility of Ethiopia had grown uneasy with the rule of Lij Iyasu. At last, when Iyasu failed to observe the important religious holiday of Meskel in the capital Addis Ababa, instead he remained in the predominantly Muslim city of Harar, they decided to strike. A number of nobles met 17 days later on 27 September, and convinced Abuna Mattewos to excommunicate Iyasu on the accusation that he converted to Islam, then announced on the steps of the Palace that Iyasu had been deposed in favor of Zewditu. The plotters had sent orders to Harar that Iyasu would be arrested, which went astray. Sources dispute exactly what Lij Iyasu's did next. Bahru Zewde states that Iyasu started to march on Addis Ababa, but his advance was blocked at Mieso by 15,000 soldiers and he fled into the Afar desert. Historian Harold G. Marcus, drawing on the reports filed by the European diplomats, states that instead Lij Iyasu had sent one force towards the capital under Dejazmach Gebre, and another, raised from loyal Afars and Somalis, to secure Dire Dawa; the Dejazmach went over to the opposing army and the Afars and Somalis deserted before reaching the city, and Iyasu fled with his bodyguard to Jijiga. Aleqa Gebre Igziabiher Elyas's narrative supports Marcus in that Iyasu fled to the desert where his Afar supporters helped him. In either case, Harar failed him as a base of support and he took refuge in the desert. Battle His father and most important supporter, Negus Mikael of Wollo, was slow to march south upon the capital and restore Iyasu to the throne, not moving until the middle of October. Yet, when he did, the Negus crushed the troops sent against him. On 18 October, Negus Mikael's troops defeated an advance force of 11,000 men in Menz and killed their leader, Ras Lul Seged. Under the command of the regent Ras Tafari (the future Emperor Haile Selassie) and Fitawrari Habte Giyorgis, a force estimated to number between 25,000 and 35,000 marched north to do battle and the two armies came to face each other at Segale on the 22nd.
