The Czech Reformation was a religious movement in the 15th century that sought to reform the Catholic Church in Bohemia. It was largely influenced by the teachings of Jan Hus, a theologian who criticized church practices and advocated for a return to the Bible's teachings. Hus's ideas gained popularity, leading to significant social and political changes in the region. Following Hus's execution in 1415, his followers, known as the Hussites, led a series of conflicts against the Catholic Church and the Holy Roman Empire. The movement eventually resulted in the establishment of the Utraquist Church, which sought to incorporate some of Hus's reforms while maintaining certain Catholic traditions.
