Crusades against the Hussites 1420 to 1431: Pope Martin V called for the destruction of the "heretics" in Bohemia, and several crusading armies marched into Bohemia

After the Council of Constance the Church demanded that Bohemia return to the old order. In 1420 Pope Martin V called by bull on all Christians to unite in a crusade for the extermination of the Wycliffites, Hussites and other heretics. Until 1431 several crusading armies marched into Bohemia, the last accompanied by the papal legate Cesarini; all were defeated or fled. In Kuttenberg Catholic miners threw hundreds of captured Hussites into disused silver mine shafts. The wars devastated Bohemia and, through Hussite raids, the neighbouring lands as well.

What happened to the people

Who was affected? Victims and numbers

  1. According to the Britannica, the vast crusading army that stood before Prague on 30 June 1420 consisted of adventurers from all parts of Europe attracted by the hope of pillage. Where the Catholics were stronger, according to the Catholic Encyclopedia, they were hard on the Hussites: in Kuttenberg the miners threw hundreds of captured Utraquists into the shafts of disused silver mines.

What happened to those affected?

  1. Further crusading armies followed: in 1421 before Saaz (Žatec), in 1427 a third of about 150,000 men, and in 1431 a fourth, sent by the unbending Martin V, with 90,000 foot and 40,000 horse, accompanied by the papal legate Cardinal Cesarini.

Only after this did the Church negotiate with the Hussites at the Council of Basel.

Background

Response of the Church

  1. In 1411, as Cardinal Colonna, Martin V had concluded the trial of Jan Hus with the sentence of excommunication. As pope he confirmed all the enactments of the Council of Constance against Hus and his followers and wrote to all concerned to return to the Church or to lend their aid in suppressing the new heresies.
    Evidence: The Catholic Encyclopedia, Bd. 7 (1910), Artikel Hussites
    „Martin V who, in 1411, as Cardinal Colonna, had terminated the trial of Jan Hus with the sentence of excommunication , now, as pope , confirmed all the council's enactments regarding him and his followers; he wrote to all whom it might concern to return to the Church or to lend their aid in suppressing the new heresies .“
