During his years in Prague University, Jan Hus got inspired by teachings of John Wycliffe, an important predecessor of Protestantism. Jan Hus (John Huss) started to preach in the Betlehem Chapel, an important centre of modern ecclesiastical thought. His lectures became extremely popular and were attended by half of Prague's population daily! A lot of his preachings criticised Catholic Church and their traditions, such as indulgences and the distinct hierarchy among the parishioners. For this reason Jan Hus became a dangerous figure in the eye of Catholic authorities and was summoned to stand a trial during the Council of Constance in 1415. There, he was accused of heresy and burned alive at the stake. His supporters started a Hussite war four years later to fight for a change in the religious structure. Their struggle inspired Martin Luther and fuelled the Protestant Reformation in the 16th century. The statue of Jan Hus on the photo was erected in 1915 to commemorate 500 years of his martyrdom. It is located on the Old Town square, 5 minutes away from the place where he taught, Charles University, and preached, Betlehem chapel.
