When John died, and Luisa became Regent for her young son, the angry nobles made a vigorous effort to dislodge the Jesuits. John's elder son, who had had a Jesuit tutor, had refused to marry, and had wished to join the Society. Men recalled the earlier King Sebastian, and said that the Jesuits were attempting to seize the crown. The Jesuit-tutor was even accused of betraying the military secrets of the country; and one of his colleagues, Father Vieira, was so badly compromised by a letter of his which was intercepted that John had been compelled to make a foreign ambassador of him; another Jesuit was the diplomatic representative of Portugal at Rome. The nobles resented this situation; but Fernandez was in too strong a position, and the rule of the Jesuits continued under the Regency. Fernandez died, however, in 1660, and it is a second Jesuit of that name (as is sometimes forgotten) who took a leading part in the extraordinary events of the year 1668. The elder prince, Theodose, had died prematurely, and Alphonso succeeded to the throne. Whether there was some incurably morbid strain in the youth, or whether the Jesuit tuition had made him incapable of serious political life, we cannot say; but, as he grew to manhood, Alphonso VI. entered upon ways of violence and licence which recall the youth of Nero. His court was filled with the wild companions of his orgies, and he paraded his vices on the streets and in the taverns of his capital. He exchanged his Jesuit confessor for a Benedictine monk, snatched the reins from the hands of his mother, and threatened to drag the country very speedily into the abyss which awaited it. Sober nobles and statesmen looked on with alarm, and it was inevitable that a conspiracy to dethrone him should shortly arise. But the details of the revolution, in which the Jesuits were very active, reflect little honour on its actors.
