But financial difficulties arose, an unsuccessful crusade was attempted, the "Black Death" came from England to Norway in 1350 and spread with great rapidity, and several other things convened to fill the people with discontent, so that the union with Norway did not prove a happy one. A separation was brought about in 1844, when Haakon, the younger son of Magnus, was made king of Norway, Magnus remaining in power until Haakon came of age, and his older son, Eric, was chosen king or heir-apparent of Sweden. It seems that this division had been preconceived by King Magnus when he gave this older son the Swedish name of Eric and to the younger the Norwegian name of Haakon, both equally characteristic of the royal lines of the respective countries.

It was during the Folkung period that there flourished one of the most remarkable and renowned of Swedish women, St. Birgitta. At the Swedish court, she was the highest functionary of Queen Blanche, where she gathered deep and strong indignation against the mighty and powerful world. By some she is considered a reformer before Luther, because she insisted on direct communication between the communicant and God without the mediation of priests or saints. Yet there was a difference between Birgitta and Luther, because the latter sought to reform institutions, while the former would reform the upholders of the institutions.

After the reign of Magnus and his sons, there came for a brief season Albrecht of Germany, and after him Queen Margaret, who united for the first time in history the three Scandinavian countries and their dependencies. This period was denominated one of unionism against patriotism, and closed with the rebellion of Denmark and the ascending of the Swedish throne by Christian of Denmark, who claimed the right of his descent from St. Eric. Then followed the public execution under edict of King Christian, when eighty-two persons were beheaded, including many bishops and men of note in Sweden.

It is needless to say that this period was followed immediately by one of revolution and reformation, characterized by much heroism and patriotism, and bringing into prominence those splendid warriors, Gustavus Vasa, Gustavus Adolphus, Charles XII, and others, and the memorable battle of Pultowa and other lesser engagements.

After this came a period of political grandeur under various rulers, notably Queen Christine, followed by what has been called the period of Liberty, or the Aristocratic Republic, under Queen Ulrica Eleonore, when literature and the arts and sciences flourished, and Swedenborg, Linnaeus, Dahlin, Tegnér, and many others came into prominence.

One of the most loved rulers of this period was Gustavus III. By his influence a revolution similar to that in France was put down, for which, at a mask ball in the Royal Opera, he was assassinated by conspiritors. It is true, historians tell us, that he was superficial, that he violated the law, had no regard for a constitutional government, and led the people into adventurous and expensive wars. Yet his noble patriotism, frank heroism, brilliant genius, and great generosity compelled the love of his countrymen. In this mixture of patriotism and universal cosmopolitanism, true genius and superficiality, earnestness and recklessness in the character of Gustavus III, the Swedes recognized peculiarities of their own national temperament, for which they love him dearly, and Tegnér has voiced this love in a few lines of his eulogy:

There rests o'er Gustav's days a golden shimmer,
Fantastic, foreign, frivolous, if you please;
But why complain when sunshine caused the glamour?
Where stood we now if it were not for these?
All culture on an unfree ground is builded,
And barbarous once the base of patriotism true;
But wit was planted, iron-hard language welded,
The song was raised, life more enjoyed and shielded,
And what Gustavian was, is, therefore, Swedish too.

On his death-bed, Gustavus III appointed his brother Charles and Charles Gustavus Armfelt members of the government during the minority of his son. Gustavus IV Adolphus was declared of age and took charge of the government when eighteen (in 1796). His guardians retired, and the new monarch ruled alone, without favorites or influential advisers. This proved most unfortunate for Sweden, for he was entirely without the gifts of a regent. He was a lover of order, economy, justice, and pure morals, but through lack of mental and physical strength his good qualities were misdirected. His father's tragic fate had a sinister effect upon his mind, the equilibrium of which was also shaken by the outrages of the revolutionists in France. Of a morbid sensibility, and without inclination to confide in any one, his religious mysticism led him into a state close to insanity. He imagined himself to be the reincarnation of Charles XII, while in Napoleon he recognized the monster of the Apocalypse, which he himself was sent to fight and conquer.

He refused any alliance with Russia and Denmark, and stubbornly resisted the friendship France wished to bestow. By his imbecility he lost Finland to the kingdom, and was compelled to abdicate in 1808. This "lunatic monarch," as he was called, was escorted out of the country with his family, never to return, and died in St. Gallin, in 1837.

Under these conditions we find Sweden at the beginning of the nineteenth century, when Charles XIII was chosen to succeed his nephew, the abdicated Gustavus IV Adolphus. 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 Jaerta, 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.
