[3] The Ottoman sultan reacted to the throne change, and the Hungarian influence which was felt more than he could afford, with sending an army into Serbia, which conquered Niš, Kruševac and besieged Novo Brdo.

[4] The combined army destroyed a large Ottoman detachment near Ravanica, for which effort the king on 19 November 1427 thanked especially Nicholas Bocskay.

But also Sultan Murat laid personal effort to encourage and support his acquired positions; in late May, after Sigismund, he arrived in the Braničevo area.

When the Hungarians in the first days of June began withdrawing, the Ottoman commander Sinan-beg attacked their back, where Sigismund was, however, with the self-sacrifice of Marko de Sentlaszlo, they were saved from disaster.

The prince fled to the Kingdom of Hungary where he had large estates, which included Zemun, Slankamen, Kupinik, Mitrovica, Stari Bečej, Kulpin, Čurug, and others.

[6] Then he arrived to Dubrovnik at the end of July 1440 and after several days continued his journey toward his coastal towns of Budva and Bar[7] which became new capitol of the remaining part of his despotate.

[15] This peace restored his Serbian rule, but Đurađ was forced to bribe John Hunyadi with his vast estates.

A crusading army led by Regent John Hunyadi of Hungary was defeated by Sultan Murad II's forces at Kosovo Polje in 1448.

Branković also captured Hunyadi at Smederevo for a short time when he was retreating home from Kosovo in 1448, due to their personal feud.

Following Hunyadi's victory over Mehmet II at the siege of Belgrade on 14 July 1456, a period of relative peace began in the region.

Serbian independence survived him for only another three years, when the Ottoman Empire formally annexed his lands following dissension among his widow and three remaining sons.

[17] His portrait in the illuminated manuscript of Esphigmenou (1429) depicts him with a mild beard, while the French nobleman Bertrandon de la Broquière who guested Đurađ in 1433 said of him "nice lord and large [in person]".

[4] He was deemed by contemporaries as the richest monarch in all of Europe; Broquière stated that his annual income from the gold and silver mines of Novo Brdo amassed to about 200,000 Venetian ducats.

The character of Đurađ Branković is portrayed by Baki Davrak in the Netflix original historical docudrama Rise of Empires: Ottoman (2020).
