The Catholic princes of the empire had long been united in a "League," with Bavaria at its head. Bavaria was, next to Austria, the most powerful state of the empire, and it had become the stronghold of the Roman faith in Germany. Now, the army of this League, under its chief, Maximilian of Bavaria, offered its services to the Emperor against the disunited and wavering Bohemians. A portion of the Bohemian army was defeated at the battle of White Mountain, just outside of Prague. Frederick, the newly elected Bohemian King, saw his troops come fleeing back to the town, and their panic seems to have seized him also. Abandoning the strong walled city, he swept such of his possessions together as he could and fled in haste from Bohemia. "The Winter King" his enemies called him in derision, because his kingship had lasted but one short winter. The citizens, disheartened by his flight, terrified by the overwhelming forces arrayed against them, surrendered to Ferdinand. Executions, proscriptions, banishments, followed without number. Every person of the land was compelled to accept Catholicism. Many burned their homes with their own hands, and fled to other countries. Seldom has liberty been so utterly trampled under foot; seldom has a land been so completely subjugated. The Bohemians, who had been one of the most intellectual, energetic peoples of Europe, here practically disappear from history as a separate nation. We turn now to the second period of this deplorable war. Its scene shifts to the domain of the unhappy Frederick upon the Rhine. He himself fled to Holland, but his land was considered as forfeited, and was deliberately desolated by Spanish troops in the service of the Emperor. The Bohemians had employed a well-known leader of mercenary troops, Count Mansfeld. When their cause was lost, Mansfeld, with most of his army, amused the Catholic forces by negotiations, till he saw his opportunity, when he slipped away from them, and led his army to the Rhine. There he continued the war in Frederick's name, though really for his own sake. His troops supported themselves by pillaging the country, and the wretched inhabitants of Frederick's Palatinate were treated almost as mercilessly by their pretended friends as by their open foes. The peasants of Upper Austria also rebelled against Ferdinand's efforts to force his religion upon them. For a time it seemed they would be as successful as the Swiss mountaineers had been. Under a peasant named Fadinger they gained several impressive victories; but he was killed, and their cause collapsed into ruin. In its last stages their struggle was taken up by an unknown leader, who was called simply "the Student." But it was too late. Remarkable and romantic as was the Student's career, his exploits and victories could not save the cause, and he perished at the head of his followers.
