A statue of Jan Zizka by Bohumil Kafka on Vitkov Hill in Prague. Jan Zizka of Trocnov and the Chalice (1360-1424) was a Czech general, follower of Jan Huss and leader of Hussite forces.
Jan Hus (or John Huss, 1369 - 1415) was a Czech priest, philosopher and one of the first church reformers. Hus attacked moral failings among the clergy and promoted some of the teachings of John Wycliffe (1331 - 1384), an English reformere who had been burned at the stake in 1384. Hus was excommunicated for his views in 1410 and burned at the stake as a heretic in Konstanz on 6 July 1415.
