The empress was fond of music, and introduced to Russia the opera and the theater. She was as intolerent to the Jews as her father had been, banishing them all from the country. She lived in constant fear of conspiracies and revolutions, and, as a desperate safeguard, established a secret inquisitorial court to punish all who should express any displeasure with the measures of government. Spies and informers of the most worthless character filled the land, and multitudes of the most virtuous inhabitants of the empire, falsely accused, or denounced for a look, a shrug, or a harmless word, were consigned to mutilation more dreadful and to exile more gloomy than the grave.

Peter the Third was grandson of Peter the Great. His mother, Anne, the eldest daughter of Peter and Catharine, married the Duke of Holstein, who inherited a duchy on the eastern shores of the Baltic containing some four thousand square miles of territory and about three hundred thousand inhabitants. Their son and only child, Peter, was born in the ducal castle at Kiel, the capital of the duchy, in the year 1728. The blood of Peter the Great of Russia, and of Charles the Twelfth of Sweden mingled in the veins of the young duke, of which fact he was exceedingly proud. Soon after the birth of Peter, his mother, Anne, died. The father of Peter was son of the eldest sister of Charles XII., and, as such, being the nearest heir, would probably have succeeded to the throne of Sweden had not the king's sudden death, by a cannon ball, prevented him from designating his successor. The widowed father of Peter, thus disappointed in his hopes of obtaining the crown of Sweden, which his aunt Ulrica, his mother's sister, successfully grasped, lived in great retirement. The idea had not occurred to him that the crown of imperial Russia could, by any chance, descend to his son, and the education of Peter was conducted to qualify him to preside over his little patrimonial duchy.
