Albert, son of the Emperor Rudolph, was the second of the house of Hapsburg who bore the title of King of the Romans. He was elected in 1298, but never went to Italy to be crowned. He came to an untimely and violent death, by the hand of his nephew John, in 1308. This is the judgment of Heaven to which Dante alludes.
