Later, Ignatius Loyola wished to take up the task of conversion, but was forbidden to do so. Instead, the pope sent out João Nunes Barreto as patriarch of the East Indies, with Andre de Oviedo as bishop; and from Goa envoys went to Ethiopia, followed by Oviedo himself, to secure the king's adherence to Rome. After repeated failures some measure of success was achieved under Emperor Susenyos I, but not until 1624 did the Emperor make formal submission to the pope. Susenyos made Roman Catholicism the official state religion but was met with heavy resistance by his subjects and by the authorities of the Ethiopian Orthodox Church, and eventually had to abdicate in 1632 in favour of his son, Fasilides, who promptly restored Ethiopian Orthodox Christianity as the state religion. He then in 1633 expelled the Jesuits, and in 1665 Fasilides ordered that all Jesuit books (the Books of the Franks) be burned.
