This happy event, combined with Isabella's unfailing affection for her wayward lord, led to improved relations between Christian and his wife's family. After the death of Maximilian, Charles became anxious to secure his brother-in-law's support in the imperial election, and in February, 1519, a treaty was concluded between the two monarchs at Brussels.[25] The Danish Envoys, Anton de Metz and Hermann Willems, Sigebritt's brother, received rich presents from Margaret, who was once more acting as Regent of the Netherlands, and she even sent a silver-gilt cup to the hated Dutchwoman herself.[26] A month later the King of Denmark was elected Knight of the Golden Fleece at a Chapter of the Order held at Barcelona, and in a letter which Charles addressed to him he expressed his pleasure at hearing good accounts of his sister and little nephew, and promised to pay the arrears of Isabella's dowry as soon as possible.[27] On the 28th of June, 1519, Charles was elected King of the Romans, and the formal announcement of his election was brought to Barcelona by Eleanor's rejected suitor, the Palatine Frederic, whom he received with open arms. A few days after this auspicious event the Queen of Denmark, on the 4th of July, 1519, gave birth to twin sons, who received the names of Philip and Maximilian. Both, however, died within a week of their baptism, upon which Sigebritt is said to have remarked that this was a good thing, since Denmark was too small a realm to support so many Princes. With the help of Dutch ships and gold, Christian succeeded in subduing the Swedish rebels, and was crowned with great solemnity in the Cathedral of Upsala on the 4th of November, 1520. But the rejoicings on this occasion were marred by the execution of ninety Swedish nobles and two Bishops, who were treacherously put to death by the King's orders. This act, which earned for Christian the title of the Nero of the North, is said to have been instigated by Sigebritt and her nephew Slagbök, a Westphalian barber, who had been raised from this low estate to be Archbishop of Lunden. The insolent conduct of these evil counsellors naturally increased the King's unpopularity in all parts of the kingdom. Yet at the same time Christian II. showed himself to be an excellent and enlightened ruler. He administered justice strictly, and introduced many salutary reforms.
