The Neapolitan revolution had just collapsed, when another broke out in Piedmont, which, though short in duration, was to have far-reaching consequences.
At that time, the King of Sardinia was Victor Emmanuel I., who succeeded his brother Charles Emmanuel in 1802, when the latter abdicated and retired to Rome, where he joined the Society of Jesus. Victor Emmanuel's only son was dead, and the throne would devolve on his youngest brother, Charles Felix, Duke of Genoa, whom reasons of state led to abandon the wish to become a monk, which he had formed as a boy of eleven, on being taken to visit a convent near Turin. But Charles Felix, though married, was without children, and the legitimate heir-presumptive was Charles Albert, Prince of Carignano, who represented the younger branch of the family, which divided from the main line in the early part of the seventeenth century. Charles Albert's father was the luckless Prince Charles of Carignano, who, alone of his house, came to terms with Napoleon, who promised him a pension, which was not paid. His mother, a Saxon Princess, paraded the streets of Turin, dressed in the last republican fashion, with her infant son in her arms. Afterwards, she gave him a miscellaneous education, that included a large dose of Rousseau from a Swiss professor. The boy was shifted from place to place, happier when his mother forgot him, than when, in temporary recollection of his existence, she called him to her. Once when he was travelling with the Princess and her second husband, M. de Montléart, Charles Albert was made to sit on the box of the carriage, in a temperature many degrees below zero.
His uncles (as the King and Charles Felix called themselves, though they were his cousins) heard with natural horror of the vagaries of the Princess of Carignano, and they extended their antipathy from the mother to the son, even when he was a child. In Victor Emmanuel, this antipathy was moderated by the easy good-nature of his character; in Charles Felix, it degenerated into an intense hatred.
It is a singular thing that Prince Metternich, from the very first, had an instinctive feeling that the unfortunate boy, who seemed the most hopeless and helpless of human creatures, would prove the evil genius of the Austrian power. He therefore set to work to deprive him of his eventual rights. He was confident of success, as fortune had arranged matters in a manner that offered a ready-made plan for carrying out the design. Victor Emmanuel had four daughters, precluded from reigning by the Salic law, which was in force in Piedmont. His wife, the Queen Maria Teresa, a woman of great beauty and insatiable ambition, was sister to the Austrian Archduke Francis d'Este, Duke of Modena. Francis had never married, having been robbed of his intended bride, the Archduchess Marie-Louise, by her betrothal to Napoleon. What simpler than to marry the eldest of the Sardinian princesses to her uncle, abrogate the Salic law, and calmly await the desired consummation of an Austrian prince, by right of his wife, occupying the Sardinian throne?
