On this date, the Tigrayan leader Kassa Mercha defeated Emperor Tekle Giyorgis II in battle near Adwa. The victory ended one of the last major struggles of the post–Zemene Mesafint era (a period of fragmented rule) and opened the way for Kassa to claim the imperial throne. This military turning point set the stage for the reign of Yohannes IV.
Kassa Mercha was crowned as Emperor Yohannes IV at Axum, a major religious and historical center. The coronation signaled a renewed attempt to strengthen imperial authority after years of regional rivalry. Yohannes would rely heavily on alliances with regional nobles and the Ethiopian Orthodox Church to govern.
Egyptian forces advanced from the Red Sea coast into the highlands, and Yohannes IV’s army met them at Gundet. The Ethiopian victory checked Egyptian expansion and boosted Yohannes’s legitimacy as a defender of the empire. It also showed that Ethiopian commanders could defeat a better-armed invader through terrain knowledge and coordinated attacks.
Yohannes IV and key commanders, including Ras Alula, defeated a larger and better-equipped Egyptian expedition near Gura. This decisive victory helped end Egypt’s push to control the northern routes and the Red Sea approaches. It reinforced Ethiopia’s independence at a time when foreign powers were increasing their influence in the region.
In May 1878, church leaders and regional elites met at Boru Meda under Yohannes IV’s supervision and resolved a major doctrinal dispute in favor of the Tewahedo position. The decision strengthened Yohannes’s alliance with the Ethiopian Orthodox Church and supported his goal of religious unity as a basis for political unity. It also helped him press for greater conformity in contested regions such as Wollo.
After being pressured by Yohannes IV, the ruler of Shewa, Menelik II (Sahle Mariam), recognized Yohannes’s authority. This reduced the risk of civil war between two powerful regional states and allowed Yohannes to focus more attention on external threats. The settlement, however, did not end long-term rivalry over succession and foreign relations.
Menelik of Shewa defeated Tekle Haymanot of Gojjam at Embabo, a major internal battle during Yohannes IV’s reign. The outcome increased Shewa’s influence in the south and west, even as Yohannes tried to manage rival nobles through appointments and negotiated boundaries. Over time, these shifting power balances made succession after Yohannes more uncertain.
Britain, Egypt, and Ethiopia signed the Hewett Treaty (also called the Treaty of Adwa) to settle disputes and arrange the evacuation of Egyptian garrisons threatened by the Mahdist uprising in Sudan. The agreement mattered because it connected Ethiopia’s security to events in Sudan and the Red Sea ports. It also reshaped regional diplomacy just before Italy expanded its presence on the coast.
Italian forces took control of Massawa, a key Red Sea port previously held by Egypt. This created a new external threat: a European power with colonial ambitions now held a major entry point to the northern highlands. Yohannes’s government viewed the move as a serious challenge, especially because access to the sea affected trade and arms supplies.
Ethiopian forces under Ras Alula defeated Mahdist troops at Kufit, showing Ethiopia could resist raids and invasions from Mahdist Sudan. The victory helped protect northern routes and communities threatened by cross-border conflict. It also reflects how Yohannes’s reign was increasingly defined by fighting on multiple frontiers.
Ras Alula’s forces defeated an Italian column near Dogali, close to Massawa. The battle intensified the confrontation between Ethiopia and Italy and made clear that coastal occupation could lead to inland war. It also increased Italian interest in securing alliances and arms deals with Ethiopian rivals of Yohannes.
After Ethiopian forces under Tekle Haymanot were defeated at Sar Weha, Mahdist troops entered Gondar and plundered the city. The attack damaged a major political and religious center and deepened the sense of crisis on Ethiopia’s western frontier. It pushed Yohannes toward a major campaign against the Mahdists, even as pressure from Italy continued in the north.
Yohannes IV led a large Ethiopian force into battle against the Mahdist State at Gallabat (also known as Metemma). He was mortally wounded during fighting on March 9–10, 1889, and died on March 10. His death triggered a succession crisis that quickly shifted power toward Shewa and set the stage for Menelik II’s rise.
After Yohannes’s death, Menelik II negotiated the Treaty of Wichale with Italy. The treaty became a major post-Yohannes turning point because its disputed wording later led Italy to claim a protectorate over Ethiopia, escalating tensions that would culminate in war. In this way, the end of Yohannes’s reign connected directly to the next era of Ethiopian state-building and foreign confrontation.
