was averted by the timely arrival of a Portuguese expedition led by Cristovão da Gama, son of the famed navigator Vasco da Gama. The Portuguese had been in the area earlier in early 16th centuries (in search of the legendary priest-king Prester John), and although a diplomatic mission from Portugal, led by Rodrigo de Lima, had failed to improve relations between the countries, they responded to the Ethiopian pleas for help and sent a military expedition to their fellow Christians. A Portuguese fleet under the command of Estêvão da Gama was sent from India and arrived at Massawa in February 1541. Here he received an ambassador from the Emperor beseeching him to send help against the Muslims, and in July following a force of 400 musketeers, under the command of Christovão da Gama, younger brother of the admiral, marched into the interior, and being joined by Ethiopian troops they were at first successful against the Muslims but they were subsequently defeated at the Battle of Wofla (28 August 1542), and their commander captured and executed. On February 21, 1543, however, a joint Portuguese-Ethiopian force defeated the Muslim army at the Battle of Wayna Daga, in which Ahmed Gurey was killed. Ahmed Gurey's widow married his nephew Nur ibn Mujahid, in return for his promise to avenge Ahmed's death, who succeeded Ahmed Gurey, and continued hostilities against his northern adversaries until he killed the Ethiopian Emperor in his second invasion of Ethiopia.

The wealthy southeastern city-states of Kilwa, Mombasa, Malindi, Pate and Lamu were all systematically sacked and plundered by the Portuguese. Tristão da Cunha then set his eyes on Ajuran territory, where the battle of Barawa was fought. After a long period of engagement, the Portuguese soldiers burned the city and looted it. Fierce resistance by the local populace and soldiers resulted in the failure of the Portuguese to permanently occupy the city, and the inhabitants who had fled to the interior eventually returned and rebuild the city. After Barawa, Tristão set sail for Mogadishu, the richest city on the East African coast at the time. Word had spread of what had happened in Barawa, and a large troop mobilization took place. Many horsemen, soldiers and battleships in defense positions were guarding
