The Bohemian Reformation (also known as the Czech Reformation or Hussite Reformation), preceding the Protestant Reformation of the 16th century, was a Christian movement in the late medieval and early modern Kingdom and Crown of Bohemia (present-day Czech Republic) striving for a reform of the Roman 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, the first radical apocalyptic religious movements of the early modern period, and the first pacifist protestant church.
