Charles XIII. succeeded his nephew. He was chosen king after a new constitution had been formulated and accepted by the Riksdag of 1809. Charles XIII. was one of the most unsympathetic of Swedish kings, but his reign marks a new period in Swedish history, commencing the era of constitutional government. The new constitution to which the king subscribed was not a radical document; it only reduced the power of the king. Hans Jærta, one of the nobles who had renounced their privileges and been active in the conspiracy against Gustavus IV., was the leading spirit of the constitutional committee and was appointed secretary of state in the new cabinet. Urgent appeals of the peasant Estate to reduce or abolish the privileges of the upper classes were of no avail, no reform of state or society yet being made. A proposition by Count von Platen to introduce a compulsory militia defence was voted down. This Riksdag, which lasted for a year, gave fuller liberties to the press, which at once used it to voice the popular dissatisfaction with the state of affairs. It was necessary to select an heir to the throne, as the old king was childless, Prince Christian August of Augustenborg being chosen, much in opposition to the nobles, who wanted the son of Gustavus IV. The prince of Augustenborg, who was Danish governor-general of Norway, accepted, and was adopted by the king, changing his name to Charles August. He was a plain, resolute and active man, unattractive in appearance, but of a kind and noble character. Beloved by the lower classes, who had effected his selection, he was treated coldly by the Gustavian aristocrats and by Queen Hedvig Elisabeth Charlotte (Princess of Oldenburg), who all favored the selection of young Gustavus, the son of exiled Gustavus IV. Reports of attempts to poison the heir-apparent were in circulation even before he arrived in Sweden. Prince Charles August himself often said that he thought he would die young by some stroke of paralysis, but he paid no attention to the warnings given him. During a parade of troops at Qvidinge, in Scania, he was suddenly seen to lose consciousness and dropped dead from his horse. Peculiarities in the investigation of the corpse, led by his physician, caused a second post-mortem examination, in which the celebrated chemist Berzelius took part. The report seemed in favor of the supposition that the death was caused by poison. The indignation of the populace knew no bounds. The friends of the government tried to coin political money by insinuating that the Gustavians, particularly Count Axel von Fersen the Younger and his sister, Countess Piper, were the responsible parties. At the burial of the dead prince the mob of Stockholm perpetrated one of the most hideous murders of a man who was without doubt innocent. When Count Fersen, in the capacity of marshal of the realm, was to open the procession, he was warned not to do so, but in pride and sense of duty resolved to meet his fate. Approaching
