The most important event connected with Austrian affairs, as distinct from those of France, England, and Holland, was the The Hungarian War. Hungarian war. Hungary was not a province of Austria, but was a distinct state. In 1526, the crowns of the two kingdoms were united, like those of England and Hanover under George I. But the Hungarians were always impatient of the rule of the Emperor of Germany, and, in the space of a century, arose five times in defence of their liberties.

In 1667, one of these insurrections took place, occasioned by the aggressive policy and government of Leopold. The Hungarians conspired to secure their liberties, but in vain. So soon as the emperor was aware of the conspiracy of his Hungarian subjects, he adopted vigorous measures, quartered thirty thousand additional troops in Hungary, loaded the people with taxes, occupied the principal fortresses, banished the chiefs, and changed the constitution of the country. He also attempted to suppress Protestantism, and committed all the excesses of a military despotism. These accumulated oppressions drove a brave but turbulent people to despair, and both Catholics and Protestants united for their common safety. The insurgents were assisted by the Prince of Transylvania, and were supplied with money and provisions by the French. They also found a noble defender in Emeric Tekeli, a young Hungarian noble, who hated Austria as intensely as Hannibal hated Rome, and who, at the head of twenty thousand men, defended his country against the emperor. Moreover, he successfully intrigued with the Turks, who invaded Hungary with two hundred thousand men, and advanced to lay siege to Vienna. This immense army was defeated by John Sobieski, to whom Leopold appealed in his necessities, and the Turks were driven out of Hungary. Tekeli was gradually insulated from those who had formed the great support of his cause, and, in consequence of jealousies which Leopold had fomented between him and the Turks, was arrested and sent in chains to Constantinople. New victories followed the imperial army, and Leopold succeeded in making the crown of Hungary, hitherto elective, hereditary in his family. He instituted in the conquered country a horrible inquisitorial tribunal, and perpetrated cruelties which scarcely find a parallel in the proscriptions of Marius and Sylla. His son Joseph, at the age of ten, was crowned king of Hungary with great magnificence, and with the usual solemnities.

When the Hungarian difficulties were settled, Leopold had more leisure to prosecute his war with the Turks, in which he gained signal successes. The Ottoman Porte was humbled and crippled, and a great source of discontent to the Christian powers of Europe was removed. By the peace of Carlovitz, (1697,) Leopold secured Hungary and Sclavonia, which had been so long occupied by the Turks, and consolidated his empire by the acquisition of Transylvania.

Leopold I. lived only to witness the splendid victories of Marlborough and Eugene, by which the power of his great rival, Louis, was effectually reduced. He died in 1705, having reigned forty-six years; the longest reign in the Austrian annals, except that of Frederic III.

He was a man of great private virtues; pure in his morals, faithful to his wife, a good father, and a kind master. He was minute in his devotions, unbounded in his charities, and cultivated in his taste. But he was reserved, cold, and phlegmatic. His jealousy of Sobieski was unworthy of his station, and his severities in Hungary made him the object of execration. He was narrow, bigoted, and selfish. But he lived in an age of great activity, and his reign forms an era in the military and civil institutions of his country. The artillery had been gradually lightened, and received most of the improvements which at present are continued. Bayonets had been added to muskets, and the use of pikes abandoned. Armies were increased from twenty or thirty thousand men to one hundred thousand, more systematically formed. A police was established in the cities, and these were lighted and paved. Jurisprudence was improved, and numerous grievances were redressed.

Leopold was succeeded by his eldest son, The Emperor Joseph. Joseph, who had an energetic and aspiring mind. His reign is memorable for the continuation of the great War of the Spanish Succession, signalized by the victories of Marlborough and Eugene, the humiliation of the French, and the career of Charles XII. of Sweden. He also restored Bohemia to its electoral rights, rewarded the elector palatine with the honors and territories wrested from his family by the Thirty Years' War, and confirmed the house of Hanover in the possession of the ninth electorate. He had nearly restored tranquillity to his country, when he died (1711) of the small-pox—a victim to the ignorance of his physicians. He was a lover and patron of the arts, and spoke several languages with elegance and fluency. But he had the usual faults of absolute princes; was prodigal in his expenditures, irascible in his temper, fond of pageants and pleasure, and enslaved by women.

He was succeeded by his brother, the Archduke Charles, under the title of Charles VI. Soon after his accession, the tranquillity of Europe was established by the peace of Utrecht, and Austria once more became the preponderating power in Europe. But Charles VI. was not capable of appreciating the greatness of his position, or the true sources of national power. He, however, devoted himself zealously to the affairs of his empire, and effected some useful reforms. As he had no male issue, he had drawn up a solemn law, called the Pragmatic Sanction, according to which he transferred to his daughter, Maria Theresa, his vast hereditary possessions. He found great difficulty in securing the assent of the European powers to this law; but, after a while, he effected his object. On his death, (1740,) Accession of Maria Theresa. Maria Theresa succeeded to all the dominions of the house of Austria.

No princess ever ascended a throne under circumstances of greater peril, or in a situation which demanded greater energy and fortitude. Her army had dwindled to thirty thousand; her treasury contained only one hundred thousand florins; a general scarcity of provisions distressed the people, and the vintage was cut off by the frost.

Under all these embarrassing circumstances, the Elector of Bavaria laid claim to her territory, and Frederic II. marched into Silesia. It has been already stated that England sympathized with her troubles, and lent a generous aid. Her appeal to her Hungarian subjects, and the enthusiasm they manifested in her cause, have also been described. The boldness of Frederic and the distress of Maria Theresa drew upon them the eyes of all Europe. Hostilities were prosecuted four years, which resulted in the acquisition of Silesia by the King of Prussia. The peace of Dresden (1745) gave a respite to Germany, and Frederic and Maria Theresa prepared for new conflicts.

The Seven Years' War has been briefly described, in connection with the reign of Frederic, and need not be further discussed. The war was only closed by the exhaustion of all the parties engaged in it.
