I want to know the answer to the following question:
What area was once the site of a significant pre-reformation movement, but now only has a small number of Protestants?
All the background I'm provided with is that "Although Czech Republic was the site of one of the most significant pre-reformation movements, there are only few Protestant adherents; mainly due to historical reasons like persecution of Protestants by the Catholic Habsburgs, restrictions during the Communist rule, and also the ongoing secularization.". Is that enough to answer the question?
