Engelbrekt met the council of state at Vadstena, escorted by 1,000 men of his best troops. Without fear or haughtiness, he pleaded the cause of his country, advising the councillors in firm and eloquent words to see to it that the foreign oppression came to an end. The council hesitated, Bishop Knut of Linkœping stating that the oath to the king could not be broken. To this Engelbrekt answered that the king had pledged many oaths but kept none, for which reason the people were freed from their oath. Upon a wholesome demonstration of force the councillors gave in and dictated a letter in which they broke their pledge to King Eric, yet giving as an excuse that they were compelled to do so. The revolt had now spread to all parts of the kingdom, at least 100,000 being armed to meet the emergency. But so carefully and quietly was the work of liberation performed that no harm was done in the parts where the peasant armies were moving. After having entered Halmstad, Engelbrekt returned to Westeros, where the army was scattered, but soon gathered again upon the report that the king with a fleet was approaching Stockholm. Upon his arrival, the king found Stockholm enclosed by a peasant army and returned to Denmark, forced to agree to an armistice. At a meeting in Arboga, Engelbrekt was elected regent. This was the first meeting in which representatives of the merchant class and the yeomanry took part, being thus the first _riksdag_ or parliament composed of the four Estates--noblemen, ecclesiastics, burghers, and yeomen.
King Eric promised, upon his return to Stockholm, to govern the country according to its laws and through Swedish men, appointing Krister Nilsson Vasa drotsete, and Charles Knutsson Bonde marsk. But so badly did he keep his promises that he was once more dethroned. The nobles hastened to elect Charles Knutsson regent, but through pressure which the peasants brought to bear it was agreed that he should share his power with Engelbrekt and lead the siege of Stockholm, while the latter should free the country from the bailiffs reinstalled by the king.
Upon his second tour through the country, Engelbrekt was seized by illness, but being called to Stockholm by an important state affair, he started over the lakes thither from Œrebro. One evening he stopped at an islet in Lake Hielmar for the night. When he saw a boat approach with Mons Bengtsson on board he staggered on a crutch down to receive him. This man sprang ashore and assaulted Engelbrekt, who tried to ward off the blows of the axe with his crutch, but failing to do so he was killed on the spot, in April, 1436. The perpetrator of this beastly murder was a son of a noble with whom Engelbrekt had been engaged in some controversy which he had recently settled to the satisfaction of both parties. The murderer escaped; but, although shielded from punishment by Marsk Charles Knutsson, he was shunned by everybody, his high-born and wealthy relations for several centuries refusing to carry the proud family name (Natt och Dag) upon which he had brought shame.
