The Hussite movement, which still exists, was new at the time of the defenstration. Jan Hus, who preached in Prague at Betlémské náměstí, called for reforms in the Catholic Church. He was executed in 1415 for heresy. A statue of Hus is at Old Town Square. Jan Žižka has a large horse statue on top of Vítkov Hill, and the entire Žižkov neighborhood is named for him. The street Jana Želivského is a main artery in Žižkov.
