Although no major Ottoman forces had been defeated, Hunyadi's "long campaign" stirred enthusiasm throughout Christian Europe. Pope Eugenius, Philip the Good, Duke of Burgundy and other European powers demanded a new crusade, promising financial or military support. The formation of a "party"a group of noblemen and clericsunder Hunyadi's leadership can be dated to this period. Their main purpose was the defence of Hungary against the Ottomans. According to a letter of Đurađ Branković, Hunyadi spent more than 63,000 gold florins to hire mercenaries in the first half of the year. An eminent representative of Renaissance humanism in Hungary, John Vitéz became Hunyadi's close friend around that time.
