In spite of this drastic edict, intended to check the spread of Hussitism in Poland, the Bohemian Hussites sent some of their emissaries to Cracow in 1427 for the purpose of conducting religious discussions. The Polish historian Długosz, who was Cardinal Oleśnicki’s secretary, reports that such a discussion, in which the Hussite representatives and the Roman Catholic doctors of the University of Cracow participated, was actually held in the city of Cracow in 1431, in the presence of the king, and characteristically adds that the heretics were vanquished, but would not admit it.[37] On January 30, 1433, due again to Cardinal Oleśnicki’s influence, another royal edict was issued against the heretics. Its intention was to lend effectiveness to ecclesiastical excommunications by providing for seizures by the starostas[38] of the property of excommunicated church offenders, who had been under the ban of the church for more than a year without effort to have it lifted.[39] It seems that even this measure did not materially help to keep the Hussite heresy in check. After the death of Wladislaus Jagiello in 1434 the Hussites were strong enough to offer some opposition to the regency of Cardinal Olesńicki; for he and his party entered into a pact of confederation at Korczyn on April 25, 1438, for the purpose of acting together to subdue any possible political or religious disturbance.[40] To counteract this, the opposition, headed by Spytek of Melsztyn, the acknowledged leader of the Hussites, entered into a similar pact on the third of May of the year following. This step on the part of the Hussites led to a clash between the two confederated parties, resulting in Spytek’s death, confiscation of his property, and in the ruin of the Spytek family.[41]
