For six years Spain groaned under a "Reign of terror," and isolated revolts only served as the occasion for fresh cruelties. The finances were squandered in futile expeditions to recover the South American colonies, which had taken advantage of Napoleon's conquest of Spain to establish their independence. In his straits for money, Ferdinand ventured to outrage national sentiment by selling Florida to the United States in 1819. Louisiana had been ceded to France in 1803, and when Mexico gained her independence in 1822, the last of the territory under Spanish rule in North America was lost to her. The reign of Ferdinand's daughter, Isabella II., was disturbed by the Carlist rebellion in 1834-1839, in which England aided the Queen with an army commanded by Sir De Lacy Evans. Spain, under Isabella II., presents a dismal picture of faction and intrigue. Policies of state had forced her into a distasteful marriage with her cousin, Francis of Assisi, and she sought compensation in sensual indulgences, endeavoring to cover the dissoluteness of her private life by a superstitious devotion to religion. She had to contend with continual revolts, and was finally compelled, in 1868, to abdicate the throne and fly to France for her life. A provisional government was formed with Serrano as President, and a new constitution was formed, by which an hereditary king was to rule, in conjunction with a senate and a popular chamber. The throne was offered to Amadeus of Aosta, the second son of Victor Emmanuel, in 1870, and he made an honest effort to discharge the difficult duties of the office. But he found the task too hard, and too distasteful, and resigned in 1873. A provisional republic was then formed, of which Castelar was the guiding spirit. But the Spaniards, trained to regard monarchy with superstitious reverence, had no sympathy with republican institutions. Don Carlos seized the opportunity to revive the claim of inalienable male succession, and raised the standard of revolt. Castelar finally threw up the office in disgust, and the administration was undertaken by a committee of officers. Anarchy was suppressed with a strong hand, but it was obvious that order could only be restored by reviving the monarchy. Foreign princes were no longer thought of, and Alfonso XII., the young son of the exiled Isabella, was restored to the throne in 1874. His first task was to terminate the Carlist war, which still continued in the North, and this was successfully accomplished in 1876. He died in 1885, and the regency was entrusted to his widow, Christina of Austria. On May 17th, 1886, a posthumous son was born, who is now the titular King of Spain. CHAPTER IV.
