Matthias, disappointed in this endeavor, now applied to the several States of his widely extended Austrian domains—to his own subjects. A general assembly was convened at Lintz. Matthias proposed his plans, urging the impolicy of allowing the Turks to retain the conquered provinces, and to remain in the ascendency in Transylvania. But here again Matthias was disappointed. The Bohemian Protestants were indignant in view of some restrictions upon their worship, imposed by the emperor to please the Catholics. The Hungarians, weary of the miseries of war, were disposed on any terms to seek peace with the Turks. The Austrians had already expended an immense amount of blood and money on the battle-fields of Hungary, and urged the emperor to send an ambassador to treat for peace. Matthias was excessively annoyed in being thus thwarted in all his plans.
Just at this time a Turkish envoy arrived at Vienna, proposing a truce for twenty years. The Turks had never before condescended to send an embassage to a Christian power. This afforded Matthias an honorable pretext for abandoning his warlike plan, and the truce was agreed to.
The incessant conflict between the Catholics and Protestants allowed Germany no repose. A sincere toleration, such as existed during the reign of Maximilian I., established fraternal feelings between the contending parties. But it required ages of suffering and peculiar combination of circumstances, to lead the king and the nobles to a cordial consent to that toleration. But the bigotry of Rhodolph and the trickery of Matthias, had so exasperated the parties, and rendered them so suspicious of each other, that the emperor, even had he been so disposed, could not, but by very slow and gradual steps, have secured reconciliation. Rhodolph had put what was called the ban of the empire upon the Protestant city of Aix-la-Chapelle, removing the Protestants from the magistracy, and banishing their chiefs from the city. When Rhodolph was sinking into disgrace and had lost his power, the Protestants, being in the majority, took up arms, reflected their magistracy, and expelled the Jesuits from the city. The Catholics now appealed to Matthias, and he insanely revived the ban against the Protestants, and commissioned Albert, Archduke of Cologne, a bigoted Catholic, to march with an army to Aix-la-Chapelle and enforce its execution.
Opposite Cologne, on the Rhine, the Protestants, in the days of bitter persecution, had established the town of Mulheim. Several of the neighboring Protestant princes defended with their arms the refugees who settled there from all parts of Germany. The town was strongly fortified, and here the Protestants, with arms in their hands, maintained perfect freedom of religious worship. The city grew rapidly and became one of the most important fortresses upon the river. The Catholics, jealous of its growing power, appealed to the emperor. He issued a decree ordering the Protestants to demolish every fortification of the place within thirty days; and to put up no more buildings whatever.
These decrees were both enforced by the aid of a Spanish army of thirty thousand men, which, having executed the ban, descended the river and captured several others of the most important of the Protestant towns. Of course all Germany was in a ferment. Everywhere was heard the clashing of arms, and every thing indicated the immediate outburst of civil war. Matthias was in great perplexity, and his health rapidly failed beneath the burden of care and sorrow. All the thoughts of Matthias were now turned to the retaining of the triple crown of Bohemia, Hungary and the empire, in the family. Matthias was old, sick and childless. Maximilian, his next brother, was fifty-nine years of age and unmarried. The next brother, Albert, was fifty-eight, and without children. Neither of the brothers could consequently receive the crowns with any hope of retaining them in the family. Matthias turned to his cousin Ferdinand, head of the Styrian branch of the family, as the nearest relative who was likely to continue the succession. In accordance with the custom which had grown up, Matthias wished to nominate his successor, and have him recognized and crowned before his death, so that immediately upon his death the new sovereign, already crowned, could enter upon the government without any interregnum.
The brothers, appreciating the importance of retaining the crown in the family, and conscious that all the united influence they then possessed was essential to securing that result, assented to the plan, and coöperated in the nomination of Ferdinand. All the arts of diplomatic intrigue were called into requisition to attain these important ends. The Bohemian crown was now electoral; and it was necessary to persuade the electors to choose Ferdinand, one of the most intolerant Catholics who ever swayed a scepter. The crown of Hungary was nominally hereditary. But the turbulent nobles, ever armed, and strong in their fortresses, would accept no monarch whom they did not approve. To secure also the electoral vote for Emperor of Germany, while parties were so divided and so bitterly hostile to each other, required the most adroit application of bribes and menaces.
Matthias made his first movement in Bohemia. Having adopted previous measures to gain the support of the principal nobles, he summoned a diet at Prague, which he attended in person, accompanied by Ferdinand. In a brief speech he thus addressed them.
"As I and my brothers," said the king, "are without children, I deem it necessary, for the advantage of Bohemia, and to prevent future contests, that my cousin Ferdinand should be proclaimed and crowned king. I therefore request you to fix a day for the confirmation of this appointment."
Some of the leading Protestants opposed this, on the ground of the known intolerance of Ferdinand. But the majority, either won over by the arts of Matthias, or dreading civil war, accepted Ferdinand. He was crowned on the 10th of June, 1616, he promising not to interfere with the government during the lifetime of Matthias. The emperor now turned to Hungary, and, by the adoption of the same measures, secured the same results. The nobles accepted Ferdinand, and he was solemnly crowned at Presburg.
