The Taborites refused to conform. The Calixtines united with the Roman Catholics and destroyed the Taborites at the Battle of Lipany on 30 May 1434. From that time, the Taborites lost their importance, though the Hussite movement would continue in Poland for another five years, until the Royalist forces of Poland defeated the Polish Hussites at the Battle of Grotniki. The state assembly of Jihlava in 1436 confirmed the "Compacta" and gave them the sanction of law. This accomplished the reconciliation of Bohemia with Rome and the Western Church, and at last Sigismund obtained possession of the Bohemian crown. His reactionary measures caused a ferment in the whole country, but he died in 1437. The state assembly in Prague rejected Wyclif's doctrine of the Lord's Supper, which was obnoxious to the Utraquists, as heresy in 1444. Most of the Taborites now went over to the party of the Utraquists; the rest joined the "Brothers of the Law of Christ" () (see history of the Moravian Church).
