Charles, duke of Brunswick, was at Paris, squandering the revenue derived from his territories, on the outburst of the July revolution, which drove him back to his native country, where he behaved with increased insolence. His obstinate refusal to abolish the heavy taxes, to refrain from disgraceful sales, to recommence the erection of public buildings, and to recognize the provincial Estates, added to his threat to fire upon the people and his boast that he knew how to defend his throne better than Charles X. of France, so maddened the excitable blood of his subjects that, after throwing stones at the duke's carriage and at an actress on whom he publicly bestowed his favors, they stormed his palace and set fire to it over his head, September 7, 1830. Charles escaped through the garden. His brother, William, supported by Hanover and Prussia, replaced him, recognized the provincial Estates, granted a new constitution, built a new palace, and re-established tranquillity. The conduct of the expelled duke, who, from his asylum in the Harzgebirge, made a futile attempt to regain possession of Brunswick by means of popular agitation and by the proclamation of democratical opinions, added to the contempt with which he treated the admonitions of his superiors, induced the federal diet to recognize his brother's authority. The ex-duke has, since this period, wandered over England, France, and Spain, sometimes engaged in intrigues with Carlists, at others with republicans. In 1836, he accompanied a celebrated female aeronaut in one of her excursions from London. The balloon accidentally upset and the duke and his companion fell to the ground. He was, however, as in his other adventures, more frightened than hurt.
