Al-Nasir Muhammad
In 1320 a conflict between the Christian monarch and Muslim Ifat leaders began. The conflict was precipitated by Al-Nasir Muhammad of Egypt. The Mamluk ruler Al-Nasir Muhammad was persecuting Christian Copts and destroying Coptic churches. The Ethiopian Emperor Amda Seyon I sent an envoy with a warning to the Mamluk ruler that if he did not stop the persecution of Christians in Egypt, he would retaliate against Muslims under his rule and would starve the peoples of Egypt by diverting the course of the Nile. According to Pankhurst, of the two threats, the diversion of Nile was an idle threat and the Egyptian sultan dismissed it because he likely realized this to be so. The fear that the Ethiopians might tamper with the Nile, states Pankhurst, was nevertheless to remain with Egyptians for many centuries.
