When the Serbian despot Đurađ Branković drew closer to Hungary, Murad II entered Serbia in March 1439. According to the TDV encyclopedia, the despot's seat of Smederevo was taken on 27 August 1439; Branković had left it to his son Grgur and fled to Hungary. The new Hungarian king, Albert, waiting at Szeged with a small army, gave no help. The Serbian Despotate was restored by the treaties of Edirne and Szeged in 1444.
