The "or else" was serious, and contained two parts. The first part was the threat to send a military legion to conquer Egypt. al-Nasir might not have balked at that: his armies were large and fierce. It was the second part that was the more serious threat: before attacking, they would divert the Nile River and cut off Egypt's greatest source of fresh water and transportation. This bold declaration came from Amda Seyon I, Emperor of Ethiopia from 1314 to 1344. Let's talk about him.
Ge'ez chronicles, the source of much of what we know about Amda Seyon, were written a century later and get some events mixed with other emperors. (Ge'ez is an ancient Semitic language.)
He was part of the Ethiopian Orthodox Church, a Christian Church that existed long before European colonization. It was part of the Coptic Orthodox Church of Alexandria since the early 300s. The chief doctrine differs from Latin and Eastern Orthodox and others in that it believes in Miaphysitism, in one perfectly unified combination of the human and divine in Christ, not in two separate natures.
Most of Amda's fighting was against Muslims in the southeast in what is now Somalia, enlarging his kingdom and spreading Christianity. In one instance, after invading the Muslim Hadiya Kingdom and exiling its people, he demanded that its ruler, Amano, visit him to pay tribute. A Muslim prophet told Amano not to go and not to be afraid, because if Amda Seyon attacked, Amano would be triumphant. Quite the contrary. The angry Amda Seyon invaded Hadiya, killed many, and took Amano prisoner. Conquering Hadiya hindered the Muslim slave trade and affected Muslim wealth in that part of the world.
After giving Amda's warning to al-Nasir, the messenger on the way back to Ethiopia was captured by Haqq ad-Din I, sultan of Ifat, who was encouraged by al-Nasir to attack Ethiopia. Haqq ad-Din tried to convert the messenger to Islam; he failed, and killed the messenger. Hearing this, Amda Seyon called up his army to attack Ifat. Amada himself with only seven horsemen rode ahead of the army to Ifat and killed many of Haqq ad-Din's soldiers. The army then destroyed Ifat's capital, and Amda took much of its gold and other materials. Haqq ad-Din was killed in battle against Amda Seyon in 1328.
The prophet who had given such bad advice to Amano is credited with continuing to stir up Muslims in the region against the powerful Ethiopian Christian kingdom. This led to Haqq ad-Din's brother and successor deciding it was time to conquer Ethiopia. That is a story for next time.
