Decisive victory for the Christian Kingdom of Hungary over Sultan Mehmet II. The price of victory was dear, however, as plague broke out in the camp, in which John Hunyadi himself, the Hungarian pricne, died three weeks later (August 11, 1456). After the Siege of Belgrade stopped the advance of Mehmed II towards Central Europe, Serbia and Bosnia were absorbed into the Empire, whereas Wallachia, the Tartar Khanate of Crimea, and Moldavia, which put up strong military resistance to Ottoman advances, retained their control over their territory, but had to pay tribute and recognize Ottoman suzerainty.
