Albert, grievously disappointed, now demanded that his second son, Frederic, should receive the crown. As soon as his name was mentioned to the States, the assembly with great unanimity exclaimed, "We will not again have an Austrian king." This led to a tumult. Swords were drawn, and two of the partisans of Albert were slain. Henry, Duke of Carinthia, was then almost unanimously chosen king. But the haughty Albert was not to be thus easily thwarted in his plans. He declared that his son Frederic was King of Bohemia, and raising an army, he exerted all the influence and military power which his position as emperor gave him, to enforce his claim. But affairs in Switzerland for a season arrested the attention of Albert, and diverted his armies from the invasion of Bohemia. Switzerland was then divided into small sovereignties, of various names, there being no less than fifty counts, one hundred and fifty barons, and one thousand noble families. Both Rhodolph and Albert had greatly increased, by annexation, the territory and the power of the house of Hapsburg. By purchase, intimidation, war, and diplomacy, Albert had for some time been making such rapid encroachments, that a general insurrection was secretly planned to resist his power. All Switzerland seemed to unite as with one accord. Albert was rejoiced at this insurrection, for, confident of superior power, he doubted not his ability speedily to quell it, and it would afford him the most favorable pretext for still greater aggrandizement. Albert hastened to his domain at Hapsburg, where he was assassinated by conspirators led by his own nephew, whom he was defrauding of his estates. Frederic and Leopold, the two oldest surviving sons of Albert, avenged their father's death by pursuing the conspirators until they all suffered the penalty of their crimes. With ferocity characteristic of the age, they punished mercilessly the families and adherents of the assassins. Their castles were demolished, their estates confiscated, their domestics and men at arms massacred, and their wives and children driven out into the world to beg or to starve. Sixty-three of the retainers of Lord Balne, one of the conspirators, though entirely innocent of the crime, and solemnly protesting their unconsciousness of any plot, were beheaded in one day. Though but four persons took part in the assassination, and it was not known that any others were implicated in the deed, it is estimated that more than a thousand persons suffered death through the fury of the avengers. Agnes, one of the daughters of Albert, endeavored with her own hands to strangle the infant child of the Lord of Eschenback, when the soldiers, moved by its piteous cries, with difficulty rescued it from her hands.
