The story

The Adal Sultanate, a Muslim state in the Horn of Africa, had long fought the Christian kingdom of Ethiopia. In 1529 its leader Ahmad ibn Ibrahim al-Ghazi, called Gragn (the left-handed) in Ethiopia, defeated the army of Emperor Lebna Dengel at Shimbra Kure. Over the next decade his forces, armed with firearms and Ottoman support, conquered much of the highlands and burned many churches and monasteries. Ahmad's armies drew on Somali, Afar and Harari fighters and on firearms that came through the Red Sea.

The emperor sought help from Portugal. A Portuguese force of about 400 musketeers under Cristovao da Gama landed in 1541, and da Gama was captured and killed in 1542. In February 1543 at Wayna Daga, the combined Ethiopian and Portuguese force killed Ahmad, and his army broke up. Both states were left weak and depopulated. Within a few decades large Oromo migrations changed the region further.

Why it mattered

The war devastated the Ethiopian highlands and nearly ended the Solomonic kingdom.
It was among the first African wars in which firearms decided the outcome.
It brought Portuguese Jesuits to Ethiopia, leading to later conflict over religion.
