The Hussites ( or Kališníci; "Chalice People") were a Christian movement in the Kingdom of Bohemia following the teachings of Czech reformer Jan Hus (c. 1369–1415), who became the best-known representative of the Bohemian Reformation and one of the forerunners of the Protestant Reformation. This predominantly religious movement was propelled by social issues and strengthened Czech national awareness.
After the Council of Constance lured Jan Hus in with a letter of indemnity, then tried him for heresy and put him to death at the stake on 6 July 1415, the Hussites fought the Hussite Wars (1420–1434) for their religious and political cause.
Among present-day Christians, Hussite traditions are represented in the Moravian Church, Unity of the Brethren, and the refounded Czechoslovak Hussite churches.
