John, however, was not to be discouraged. Learning that the Emperor Charles V. was on his way homeward, after his military success at Tunis, he resolved to avail himself of the opportunity. Charles would be entitled by the exploits he had performed to a triumph, at which custom allowed him to ask any favour he pleased from the Pope. He besought Charles therefore to make the establishment of the Inquisition in Portugal the privileged request. Charles assented,[170] and the Pope, though sorely unwilling, was obliged to grant it. At the same time, however, he stipulated that all the Portuguese Jews who had been imprisoned up to that time should be released from prison, and receive a free pardon. This condition the king refused to comply with; and the Pope had to exercise his personal authority, placarding the pardons on the doors of the churches, and sending his own officers to release the prisoners. The Inquisition, however, was set up in Portugal; and the same results attended the measure as had followed from it elsewhere, on all other occasions. Many of the secret Jews, foreseeing these, fled to other lands; where, if not actually safe from persecution, they would be at all events less liable to it. Not many years afterwards, Jews and New Christians were to be met with in considerable numbers in various parts of the newly discovered regions of America, both in the countries which had been taken possession of by Spain and those which had fallen to the share of Portugal. In Africa also, and all over Asia, they settled—sometimes a scattered few, sometimes in larger communities. So numerous, indeed, were the emigrants, and so injurious to the national welfare was their departure found to be, that repeated edicts were issued by the kings of Portugal, forbidding it on the severest penalties. The simple method of detaining them, by making their residence in the country agreeable, or even endurable, to them, does not seem to have been thought of.
