The Portuguese government appealed to Benedict XIV. to take action against the Society. The Pope appointed Saldanha an apostolic visitor to examine into the charges that had been made. Though the instructions laid down for the guidance of the visitor were precise in every detail, Saldanha, unmindful of the restrictions imposed by the Pope and without hearing any evidence that might favour the accused, decided against the Jesuits and procured the withdrawal of their faculties in Lisbon (1758). In September of that year a plot directed against one of the royal officials, but supposed to have for its object the murder of the king, was discovered and attributed without any evidence to the Jesuits. They and many of their supposed allies among the nobility were arrested and thrown into prison; their schools were closed, and various fruitless attempts were made to induce the younger members to disown the Society. Finally in September 1759 a decree of banishment was issued against the Jesuits. Most of them were arrested and despatched to the Papal States, while others of them, less fortunate, were confined as prisoners in the jails of Portugal. Father Malagrida, one of the ablest and most saintly men of the Society, was put to death on a trumped-up charge of heresy (1761). Clement XIII. (1758-1769) made various attempts to save the Society, and to prevent a breach with Portugal, but Pombal determined to push matters to extremes. The Portuguese ambassador at Rome suddenly broke off negotiations with the Holy See and left the city, while the nuncio at Lisbon was escorted to the Spanish frontier (1760). For a period of ten years (1760-1770) friendly relations between Rome and Portugal were interrupted.
