which european group forged an alliance with the ethiopian kingdom in the 1540s
History of Ethiopia Between 1528 and 1540, armies of Muslims, under the Imam Ahmad ibn Ibrihim al-Ghazi, entered Ethiopia from the low country to the south-east, and overran the Abyssinian Kingdom, obliging the Emperor to take refuge in the mountain fastnesses. In this remote location, the ruler again turned to the Portuguese. João Bermudes, a subordinate member of the mission of 1520, who had remained in the country after the departure of the embassy, was, according to his own statement (which is untrustworthy), ordained successor to the Abuna (archbishop), and sent to Lisbon. Bermudes certainly came to Europe, but with what credentials is not known.
