Birger himself had a queen for his wife, having married the dowager Queen Mechthild of Denmark, and to increase his importance he assumed the title of duke, never before borne in Sweden. But many of the peasants called him king, since he governed the kingdom and was married to a queen. But meanwhile poor Bishop Kol was dying of grief for the deed of shame into which this proud lord had led him.
Shall we here tell an interesting and romantic story about one of Birger's brothers? He was a judge in East Gothland, his name being Bengt, and had fallen deeply in love with a damsel named Sigrid, whose family was not rich nor great, though she herself was so beautiful that she was widely known as Sigrid the Fair.
Duke Birger was not pleased with the idea of such a match, thinking the girl, though of noble birth, of far too lowly rank to mate with a member of his family. But in such things Judge Bengt had a will of his own and he married Sigrid without Birger's consent. This so displeased the proud jarl that he sent Bengt a cloak, half of which was made of gold brocade and the other of coarse and common baize. This was in token of the difference in rank of the families of Bengt and Sigrid and a significant hint that he should separate from his new wife.
But Bengt was equal to the situation. He covered the coarse half of the cloak with gold, pearls and precious stones so as to make it more valuable than the other, and this he sent to his brother with no other answer. This only irritated Birger the more, and he sent back the message, "that he would speak with his brother face to face about this affair," adding some harsh words which were also repeated to Bengt.
Then, soon after this, the angry jarl saddled his horse and rode with a large company to Ulfasa, where Bengt lived. When the judge saw the jarl's train near at hand he fled from his house to the woods, leaving his wife, whom he had carefully instructed how to act, to meet his irritated brother.
When the angry jarl rode into the court, fully prepared to call his erring brother severely to account, he was surprised to see the fairest woman he had ever beheld come forward to meet him. She was adorned with the most costly robes and precious ornaments she could command and everything had been done to enhance the charm of her beauty. Stepping forth before the jarl, who gazed at her with astonishment, she bowed low and welcomed him with all honor and courtesy.
So astonished was Birger with the charming vision that he sprang from his horse and seized Sigrid in his arms, saying, "Had my brother not done this I should have done it myself."
Leading him to the house, she entertained him with the best cheer, and Bengt being sent for to the wood, the two brothers were fully reconciled. Such an effect have the charms of a fair woman over the pride and passion of men.
A few words must serve to finish the story of Birger Jarl. The greatest and most valuable service of his reign lay in the new laws he gave the country and his doing away with many of the old barbarian customs to replace them with the customs of civilization.
Before this time it was the common practice for the relatives of a murdered man to avenge him on the family of the murderer, thus giving rise to long and bloody feuds. This custom Birger forbade, ordering every one to seek redress for injury at the courts of justice. He also passed four Laws of Peace, viz.: for the Peace of the Church, of Women, of House, and of Assize.
