The Hussites were a Czech proto-Protestant Christian movement that followed the teachings of reformer Jan Hus, a part of the Bohemian Reformation.

The Bohemian Reformation, preceding the Reformation of the 16th century, was a Christian movement in the late medieval and early modern Kingdom and Crown of Bohemia striving for a reform of the Catholic Church. Lasting for more than 200 years, it had a significant impact on the historical development of Central Europe and is considered one of the most important religious, social, intellectual and political movements of the early modern period. The Bohemian Reformation produced the first national church separate from Roman authority in the history of Western Christianity, the first apocalyptic religious movement of the early modern period, and the first pacifist Protestant church.
