The Emperor Maximilian II. had left five stalwart sons, so that there had
seemed little probability that the younger line, the sons of his brother,
would succeed. But all the five were childless, and now the son of
Archduke Charles, who had died in 1590, had become the natural heir after
the death of Matthias to the immense family honours--his cousins
Maximilian and Albert having resigned their claims in his favour.

Ferdinand, twelve years old at his father's death, had been placed under
the care of his maternal uncle, Duke William of Bavaria. By him the boy
was placed at the high school of Ingolstadt, to be brought up by the
Jesuits, in company with Duke William's own son Maximilian, five years
his senior. Between these youths, besides the tie of cousinship, there
grew up the most intimate union founded on perfect sympathy in religion
and politics.

When Ferdinand entered upon the government of his paternal estates of
Styria, Carinthia, and Carniola, he found that the new religion, at which
the Jesuits had taught him to shudder as at a curse and a crime, had been
widely spreading. His father had fought against heresy with all his
might, and had died disappointed and broken-hearted at its progress. His
uncle of Bavaria, in letters to his son and nephew, had stamped into
their minds with the enthusiasm of perfect conviction that all happiness
and blessing for governments depended on the restoration and maintenance
of the unity of the Catholic faith. All the evils in times past and
present resulting from religious differences had been held up to the two
youths by the Jesuits in the most glaring colours. The first duty of a
prince, they had inculcated, was to extirpate all false religions, to
give the opponents of the true church no quarter, and to think no
sacrifice too great by which the salvation of human society, brought
almost to perdition by the new doctrines, could be effected.
