His son, Louis Philippe, acquired the sobriquet of _le Gros_, or the Fat, from his excessive corpulence. His unwieldy body probably contributed to that indolence of mind which induced him to withdraw from nearly all participation in political life. Louis XV. was one of the vilest of men, and by a portion of his subjects was thoroughly detested. Exasperated by an act of gross despotism, the deputies from Brittany offered to furnish Louis Philippe with sixty thousand men, completely armed, to overthrow the reigning dynasty, and to establish in its place the House of Orleans. The prince received the deputation courteously, but decidedly declined embarking in the enterprise, avowing that he had not sufficient energy of character to meet its demand, and that he was too much attached to his relative, Louis XV., to engage in a conspiracy against him. He was an amiable, upright man, avoiding notoriety, and devoting himself to literary pursuits. Being of the blood royal, the etiquette of the French court did not allow him to enter into marriage relations with any one in whose veins the blood of royalty did not flow. His first wife, Louise Henriette de Bourbon Conti, was a princess of royal lineage. Upon her death he married Madame de Montesson, a beautiful woman, to whom he was exceedingly attached. But the haughty Court of France refused to recognize the marriage. Notwithstanding his earnest solicitations, he was not permitted to confer upon her the title of Duchess of Orleans. Even when he died, in the year 1785, court etiquette would not allow his widow to assume any public demonstrations of mourning. "The blood of a Capet," it was said, "is too pure to admit of a _recognized_ alliance below the rank of royalty." Such, in brief, was the character and career of the first four dukes of this illustrious house. We are thus brought down to the exciting scenes of modern history--to scenes in which the house of Orleans has acted a part so conspicuous as to attract the attention of the civilized world. The fourth duke of whom we have spoken, and his first wife, Henrietta de Bourbon Conti, had a son born on the 13th of April, 1747, at the Palace of St. Cloud. They gave their child the name of Louis Philippe Joseph d'Orleans. During the life-time of his father he bore the title of the Duke de Chartres. No expense was spared in his education, his parents providing for him teachers of the highest eminence in all the branches of knowledge. Though the young prince developed much energy and activity of mind, he was not fond of study, and did not make any remarkable progress in book-learning.
