Queen Mary, who had been brought up in the Roman faith, tried to make England again a Roman Catholic country, and in the later years of her reign encouraged severe persecutions, causing many to be burned at the stake, in the hope of thus crushing out heresy. After her death, however, in 1558, Queen Elizabeth adopted a more moderate position, and the church of England was established by law in much the form it had possessed at the death of Henry VIII. In the meantime, however, there had been growing up a far more spontaneous religious movement than the official Reformation which has just been described. Many thousands of persons had become deeply interested in religion and enthusiastic in their faith, and had come to hold different views on church government, doctrines, and practices from those approved of either by the Roman Catholic church or by the government of England. Those who held such views were known as Puritans, and throughout the reign of Elizabeth were increasing in numbers and making strenuous though unsuccessful efforts to introduce changes in the established church. The reign of Elizabeth was marked not only by the continuance of royal despotism, by brilliant literary production, and by the struggle of the established church against the Catholics on the one side and the Puritans on the other, but by difficult and dangerous foreign relations. More than once invasion by the continental powers was imminent. Elizabeth was threatened with deposition by the English adherents of Mary, Queen of Scots, supported by France and Spain. The English government pursued a policy of interference in the internal conflicts of other countries that brought it frequently to the verge of war with their governments and sometimes beyond. Hostility bordering on open warfare was therefore the most frequent condition of English foreign relations. Especially was this true of the relations with Spain. The most serious contest with that country was the war which culminated in the battle of the Armada in 1588. Spain had organized an immense fleet which was intended to go to the Netherlands and convoy an army to be taken thence for the invasion of England. While passing through the English Channel, a storm broke upon them, they were attacked and harried by the English and later by the Dutch, and the whole fleet was eventually scattered and destroyed. The danger of invasion was greatly reduced after this time and until the end of Elizabeth's reign in 1603.
