In the late 1800s, Italy used commercial purchases around Assab to gain a base on the Red Sea coast. This foothold helped Italy enter the wider European competition for territory in northeast Africa and prepared the way for later expansion inland.
In 1885, Italian forces landed at Massawa and other coastal points, expanding beyond earlier holdings. Control of Massawa strengthened Italy’s supply lines and made further moves toward the highlands more feasible.
On May 2, 1889, Menelik II and Italy signed the Treaty of Wuchale (also spelled Ucciali/Wichale). Italy gained recognition for its Red Sea possessions and promised money and large arms supplies, tying Ethiopian and Italian interests together on paper.
A crisis began because Article 17 was not equivalent in the two official texts. In the Amharic version, the Ethiopian ruler could use Italy’s help in foreign relations, while the Italian version said he must—a change Italy treated as authority to control Ethiopia’s diplomacy.
Later in 1889, Italy formally communicated its Article 17 interpretation to other European powers, aiming to have them treat Ethiopia as an Italian protectorate (a state whose foreign relations are controlled by another). This step turned a treaty-translation dispute into an international diplomatic conflict.
On January 1, 1890, Italy officially proclaimed Eritrea as a colony. This created a more permanent base for Italian administration and military operations along Ethiopia’s northern frontier.
By 1890, Menelik II rejected Italy’s claim that the treaty made Ethiopia a protectorate. The disagreement over who controlled Ethiopian diplomacy became a central issue in relations and pushed both sides toward confrontation.
In 1893, Menelik II formally denounced the entire treaty. This ended hopes of resolving the dispute through the treaty framework and set the stage for Italy to try to enforce its position by military pressure.
On January 13, 1895, Italian forces defeated troops led by Ras Mengesha Yohannes at Coatit. The fighting marked a major escalation and is often treated as the opening of the First Italo-Ethiopian War’s main phase in the borderlands of Eritrea and northern Ethiopia.
On December 7, 1895, Ethiopian forces under Ras Makonnen attacked and destroyed an Italian forward position at Amba Alagi. The battle showed that Ethiopia could defeat Italian columns in the highlands and encouraged wider Ethiopian mobilization.
In January 1896, Ethiopian forces besieged the Italian fort at Mekelle. The Italians surrendered and were allowed to withdraw, which gave Ethiopia a morale boost and helped set conditions for a decisive encounter soon afterward.
On March 1, 1896, Menelik II’s army decisively defeated the Italian force at Adwa. The outcome ended Italy’s attempt to impose a protectorate by force and became a turning point for Ethiopian sovereignty in an era of intense European colonization.
On October 23, 1896, Ethiopia and Italy signed the Treaty of Addis Ababa to formally end the war. Italy agreed to abrogate (cancel) the Treaty of Wuchale and recognized Ethiopia’s independence, closing the diplomatic crisis that began with the contested Article 17 wording.
