Albert succeeded to the duchy of Austria on his father's death in 1404. After receiving a good education, he undertook the government of Austria in 1411, and succeeded, with the aid of his advisers, in ridding the duchy of the evils which had arisen during his minority. He assisted the German emperor Sigismund, who was also king of Hungary and Bohemia, in his campaigns against the Hussites, and in 1422 married Elizabeth, daughter and heiress of Sigismund, who designated him as his successor. (Note that she was not the daughter of Sigismund's first wife Mary of Hungary, and thus not descended from the old Arpád kings of Hungary.)
When Sigismund died in 1437, Albert was crowned king of Hungary on January 1, 1438, and although crowned king of Bohemia six months later, he was unable to obtain possession of the country. He was engaged in warfare with the Bohemians and their Polish allies, when on March 18, 1438 he was chosen as German emperor at Frankfurt, an honour which he does not appear to have sought. He thus was "King of the Romans", but he was not crowned as Turks, he died on October 27, 1439 at Langendorf, and was buried at Stuhlweissenburg. Albert was an energetic and warlike prince, whose short reign gave great promise of usefulness for Germany.
Her maternal grandfather was Count Herman II of Celje, whose parents were the Slovenian ruler Count Herman I of Celje and Catherine of Bosnia (who apparently descended also from Nemanjic kings of Serbia and from Catherine of Hungary, a daughyter of Stephen V of Hungary).
