Budai Nagy Antal Revolt The Budai Nagy Antal Revolt , or Bobâlna Revolt ( Hungarian " Erdélyi paraszt felkelés " , that is " Transylvanian peasant revolt " , meaning " Bobâlna Revolt " ) , of 1437 in Transylvania , was the only significant popular revolt in the Kingdom of Hungary prior to the great peasant war of 1514 . The event is named after the leader of the revolt , Antal Nagy de Buda , or is simply called the " Transylvanian Peasant Revolt " . Events leading to the revolt . In order to tackle financial burdens resulting from the Hussite wars and military campaigns against the Ottoman Empire , King Sigismund put lower value silver coins into circulation in Hungary . György Lépes , the Bishop of Transylvania decided in 1434 not to collect taxes until this money was used , however , demanded the arrears of the tithes in one sum three years later , in 1437 , when valuable golden coins were issued again by the royal treasury . The peasants , having had received revenues in silver coins earlier , were not able to pay taxes in the new valuable currency . When the peasants refused to pay , the bishop excommunicated them . The peasants were also aggrieved over the unwillingness of their lords to respect their right of free movement . Furthermore , the bishop required payments from petty noblemen and even from Vlach ( Romanian ) peasants who did not belong to the Roman Catholic Church . The rebellion breaks out . The rebellion broke out in northern Transylvania , but soon spread to the counties of Szatmár ( Satu Mare ) and Szabolcs . In June an army of Hungarian and Vlach ( Romanian ) peasants built a camp on a hill at Bábolna ( Romanian : Bobâlna ) . They were joined by petty noblemen and priests . They proclaimed and demanded the recognition of an Estate of their own , called " universitas Hungarorum et Valachorum - Estate of Hungarians and Romanians " and were led by a poor nobleman called Antal Nagy de Buda and five other captains ( three Hungarian peasants , a Romanian peasant , and a burgher from Kolozsvár ( Cluj - Napoca ) ) . The rebels sent envoys to Transylvanian voivode László Csák . The voivode promptly executed the envoys but , after the rebel troops scored a victory over his forces , he feigned willingness to negotiate . On 6 July at Kolozsmonostor ( Cluj - Mănăştur ) a contract was signed between the parties that met many of the rebels ' demands . Both parties also sent envoys to King Sigismund of Hungary asking for arbitration . However , on 16 September the Transylvanian nobility , the Saxon burghers , and the Székely free guards formed an alliance of mutual aid , which was termed the Union of Kápolna ( Căpâlna ) . The alliance was designed to protect Transylvania from Tatar and Ottoman incursions , and to support feudal landlords in the noble counties ( Comitates ) in their fight against the peasants . A new treaty with the rebels was signed on 6 October at Apáti ( Apateu ) , which repealed some aspects of the previous agreement . The new agreement exempted petty nobles from paying taxes , thus , left peasants alone with their requests . When Sigismund died in December , the allies attacked and defeated the rebels in a pitched battle . Antal Nagy de Buda died on the battlefield . They also besieged Kolozsvár , where the surviving rebels found refuge , and took the town in January 1438 . The leaders of the revolt were executed at Torda ( Turda ) , while Kolozsvár was deprived of its urban privileges and its inhabitants declared peasants . On 2 February the alliance set out by the Union of Kápolna was renewed and would later become the Union of Three Nations . Further reading .
