Diogo Lopes de Sequeira
In 1518, Diogo replaced Lopo de Soares as the man in charge of a mission to find Prester John, deemed the king of Abyssinia, and to create an alliance with this king. The result was the first Portuguese embassy to Ethiopia, which took place over the years 1520-1526. This undertaking is documented in the Letters of Diogo Lopes de Sequeira.
