The tragedy of which Paul I. was the victim, called Alexander to the throne of all the Russias in the twenty-fourth year of his age. He had been carefully educated under the eye of his grandmother, the able Catharine. Her choice of a preceptor in La Harpe, a Swiss republican, who had fraternized with the revolutionists of France, was a problem the sovereigns of Europe could not solve; but after all, republicanism can not be very far removed from despotism, if we may judge from its consequences, since history shows us that republics end in despotic sovereignties. Catharine was doubtless aware of this fact when she gave La Harpe the direction of her grandson's education. It was prudent to avoid Russian ascendency in a matter so important to herself, for Catharine was a foreigner and a usurper, a fact of which a native instructor might have availed himself to her disadvantage. In educating her grandsons, the great empress excluded the fine arts. She wished to make them rulers, not professors of music and painting; and she was right; La Harpe inspired, it is said, his imperial pupil with lessons of generosity and truth it was no easy task to eradicate during his eventful life. The policy of Catharine made her determine to give wives to her grandsons as soon as they were marriageable. Her jealousy, or her profound judgment, made her overlook Paul in the succession of Russia, by a mental but not a public exclusion. Alexander was destined by her to the throne of which she had robbed his father Constantine, she proudly hoped to place on one she designed to win from the Sultan, an ambitious desire which was never realized. Three German princesses came to the court of St. Petersburg, in order that Catharine might make choice of suitable brides for her grandsons. The empress thoughtfully expected the arrival of her guests, whose approach she watched from a window of her palace. The empress, whose motions were dignified and graceful, attached great importance to deportment; she formed her opinions of young people by that standard. The destinies of these princesses were decided the instant they alighted from their traveling carriage. The first leaped down without availing herself of the step. The empress shook her head, "She will never be empress of Russia, she is too precipitate," was her internal remark. The second entangled her feet in her dress, and with difficulty escaped a fall. "She is not the empress, for she is too awkward," and Catharine again turned her eyes on the carriage with anxious curiosity. The third princess descended very gracefully; she was beautiful, majestic, and grave. "Behold the future Empress of Russia," said Catharine. This princess was Louisa of Baden.
