Final years

In 1428, Sigismund led another campaign against the Turks, but again with few results. In 1431, he went to Milan where on 25 November he received the Iron Crown as King of Italy; after which he remained for some time at Siena, negotiating for his coronation as emperor and for the recognition of the Council of Basel by Pope Eugenius IV. He was crowned emperor in Rome on 31 May 1433, and after obtaining his demands from the pope returned to Bohemia, where he was recognized as king in 1436, though his power was little more than nominal. Shortly after he was crowned, Pope Eugenius began attempts to create a new anti-Ottoman alliance. This was sparked by an Albanian revolt against the Ottomans, which had begun in 1432. In 1435, Sigismund sent Fruzhin, a Bulgarian nobleman, to negotiate an alliance with the Albanians. He also sent Daud, a pretender to the Ottoman throne, in early 1436. However, following the defeat of the rebels in 1436, plans for an anti-Ottoman alliance ended. Sigismund died on 9 December 1437 at Znojmo (German: Znaim), Moravia (now Czech Republic), and as ordered in life, he was buried at Nagyvárad, Hungary (today Oradea, Romania), next to the tomb of the King Saint Ladislaus I of Hungary, who was the ideal of the perfect monarch, warrior and Christian for that time and was deeply venerated by Sigismund. By his second wife, Barbara of Celje, he left an only daughter, Elisabeth of Luxembourg, who was married to Albert V, duke of Austria (later German king as Albert II) whom Sigismund named as his successor. As he left no sons, his line of the House of Luxembourg became extinct on his death.
