Ahmad ibn Ibrahim al-Ghazi
In 1507, Mateus, an Armenian, had been sent as an Ethiopian envoy to Portugal to ask for aid against the Adal Sultanate. In 1520, an embassy under Dom Rodrigo de Lima landed in Ethiopia (by which time Adal had been remobilized under Ahmad ibn Ibrahim al-Ghazi). An interesting account of the Portuguese mission, which lasted for several years, was written by Francisco Álvares, the chaplain.
