representations, to win over to his cause the ecclesiastical electors,
and also Maximilian, Duke of Bavaria, at Munich. The whole issue of the
war, the fate of Frederick and the Emperor, were now dependent on the
part which the Union and the League should take in the troubles of
Bohemia. It was evidently of importance to all the Protestants of
Germany that the King of Bohemia should be supported, while it was
equally the interest of the Roman Catholics to prevent the ruin of the
Emperor. If the Protestants succeeded in Bohemia, all the Roman
Catholic princes in Germany might tremble for their possessions; if they
failed, the Emperor would give laws to Protestant Germany. Thus
Ferdinand put the League, Frederick the Union, in motion. The ties of
relationship and a personal attachment to the Emperor, his
brother-in-law, with whom he had been educated at Ingolstadt, zeal for
the Roman Catholic religion, which seemed to be in the most imminent
peril, and the suggestions of the Jesuits, combined with the suspicious
movements of the Union, moved the Duke of Bavaria, and all the princes
of the League, to make the cause of Ferdinand their own.

According to the terms of a treaty with the Emperor, which assured to
the Duke of Bavaria compensation for all the expenses of the war, or the
losses he might sustain, Maximilian took, with full powers, the command
of the troops of the League, which were ordered to march to the
assistance of the Emperor against the Bohemian rebels. The leaders of
the Union, instead of delaying by every means this dangerous coalition
of the League with the Emperor, did every thing in their power to
accelerate it. Could they, they thought, but once drive the Roman
Catholic League to take an open part in the Bohemian war, they might
reckon on similar measures from all the members and allies of the Union.
Without some open step taken by the Roman Catholics against the Union,
no effectual confederacy of the Protestant powers was to be looked for.
They seized, therefore, the present emergency of the troubles in Bohemia
to demand from the Roman Catholics the abolition of their past
grievances, and full security for the future exercise of their religion.
They addressed this demand, which was moreover couched in threatening
language, to the Duke of Bavaria, as the head of the Roman Catholics,
and they insisted on an immediate and categorical answer. Maximilian
might decide for or against them, still their poin
