Which treaty did Menelik II reject, leading to the Italian invasion and the subsequent Battle of Adwa?

The treaty that Menelik II rejected, which led to the Italian invasion and the subsequent Battle of Adwa, was the Treaty of Wuchale. Signed in 1889 between Italy and Ethiopia, this treaty was intended to establish a friendship and define boundaries.

However, a dispute arose over the translation of a key article in the treaty. The Italian version implied that Ethiopia agreed to become a protectorate of Italy, giving Italy significant control over Ethiopian foreign affairs. In contrast, the Ethiopian version did not reflect such a commitment. Menelik II, recognizing the loss of sovereignty that the Italian version entailed, rejected this interpretation, seeing it as a threat to Ethiopian independence.

Menelik's refusal to accept the Italian version of the treaty led to tensions that escalated into the First Italo-Ethiopian War. This culminated in the Battle of Adwa in 1896, where Ethiopian forces, under the leadership of Menelik II, decisively defeated the Italian army. The victory helped Ethiopia maintain its independence and assert its sovereignty on the world stage.
